    2002-01-01

    The nocturnal land breeze at the Kennedy Space Center (KSC) and Cape Canaveral Air Force Station (CCAFS) is both operationally significant and challenging to forecast. The occurrence and timing of land breezes impact low-level winds, atmospheric stability, low temperatures, and fog development. Accurate predictions of the land breeze are critical for toxic material dispersion forecasts associated with space launch missions, since wind direction and low-level stability can change noticeably with the onset of a land breeze. This report presents a seven-year observational study of land breezes over east-central Florida from 1995 to 2001. This comprehensive analysis was enabled by the high-resolution tower observations over KSC/CCAFS. Five-minute observations of winds, temperature, and moisture along with 9 15-MHz Doppler Radar Wind Profiler data were used to analyze specific land-breeze cases, while the tower data were used to construct a composite climatology. Utilities derived from this climatology were developed to assist forecasters in determining the land-breeze occurrence, timing, and movement based on predicted meteorological conditions.

    1971-01-01

    Description of a radar-observed apparent land breeze front 12 to 14 n mi off the coast of Wallops Island, Va. Accompanying meteorological data show the land breeze at the shore to be a layer of cold air less than 300 ft deep moving seaward at approximately 2 knots. The radar observations show the land breeze vertical frontal surface sloping landward at about 20 deg, with convection over the warm water increasing the layer thickness to 2000 ft near the frontal zone. The radar-observed horizontal frontal surface is a sharp scalloped line echo in the lower 1000 ft, but becomes diffuse above. As the local circulation during daylight hours changes to a sea breeze, the land breeze front recedes toward land and dissipates.

  7. Interaction of the sea breeze with a river breeze in an area of complex coastal heating

    1991-01-01

    The interaction of the sea-breeze circulation with a river-breeze circulation in an area of complex coastal heating (east coast of Florida) was studied using a 3D finite-element mesoscale model. The model simulations are compared with temperature and wind fields observed on a typical fall day during the Kennedy Space Center Atmospheric Boundary Layer Experiment. The results from numerical experiments designed to isolate the effect of the river breeze indicate that the convergence in the sea-breeze front is suppressed when it passes over the cooler surface of the rivers.

    Chiba, Osamu; Kobayashi, Fumiaki; Naito, Gen'ichi; Sassa, Koji

    1999-04-01

    Thermodynamical observations by a helicopter have been conducted to study the internal structure of the sea breeze blowing inland from Tosa Bay during three periods (September 1993, November 1994 and 1995). Inland-intrusion distances of the midday sea breeze observed at each flight leg were in the 10-25-km range, depending on the intensity of the ambient flow associated with the gradient wind, atmospheric stratification, and the geographical features of the observed area.The sea breeze observed over the sea had well-defined features, in particular a turbulent wake behind the head of the sea-breeze front and a closed sea-breeze circulation cell containing the subsidence of the return flow. In addition, a moist layer distributed around 15-20 km offshore forms because the land breeze moves in this region. Moreover, a calm condition exists from the coast to about 10 km offshore. Both phenomena are found before the onset of the sea breeze in the early morning. Such remarkable characteristics of the sea breeze are found over the sea, with a background of land-sea configuration that consists of a flat plain with small mountains and a bay opened out to sea.

  15. Winter Lake Breezes near the Great Salt Lake

    Crosman, Erik T.; Horel, John D.

    2016-05-01

    Case studies of lake breezes during wintertime cold air pools in Utah's Salt Lake Valley are examined. While summer breezes originating from the Great Salt Lake are typically deeper, of longer duration, and have higher wind speeds than winter breezes, the rate of inland penetration and cross-frontal temperature differences can be higher during the winter. The characteristics of winter breezes and the forcing mechanisms controlling them (e.g., snow cover, background flow, vertical stability profile, clouds, lake temperature, lake sheltering, and drainage pooling) are more complex and variable than those evident in summer. During the afternoon in the Salt Lake Valley, these lake breezes can lead to elevated pollution levels due to the transport of fine particle pollutants from over the Great Salt Lake, decreased vertical mixing depth, and increased vertical stability.

  20. Sulfate accumulation in a sea breeze/land breeze circulation system

    International Nuclear Information System (INIS)

    An atmosphere tracer study using SF6 was conducted on July 22, 1977, to examine the origin of the high particulate sulfate concentrations observed in coastal Los Angeles County. It was found that the sea breeze/land breeze circulation system in the Los Angeles Basin both increases the retention time for sulfate formation in the marine environment and causes individual air parcels to make multiple passes over large coastal emissions sources. Day-old sulfur oxides emissions advected out to sea by the land breeze at night were estimated to be the largest single contributor to 24-hour average sulfate air quality over land the next day. In contrast, 24-hour average SO2 concentrations were dominated by fresh emissions from nearby sources. The overall rate of SO2 transformation to form particular sulfur oxides along some trajectories that spent a considerable time over the ocean at night probably exceeds the rate that can be explained by known photochemical processes acting during the daylight portion of these trajectories. This suggests that appreciable aerosol formation may occur in a polluted marine environment at night

  1. Cosmic Rays in a Galactic Breeze

    CERN Document Server

    Taylor, Andrew M

    2016-01-01

    Motivated by the discovery of the non-thermal Fermi bubble features both below and above the Galactic plane, we investigate a scenario in which these bubbles are formed through Galacto-centric outflow. Cosmic rays (CR) both diffusing and advecting within a Galactic breeze outflow, interacting with the ambient gas present, give rise to gamma-ray emission, providing an approximately flat surface brightness profile of this emission, as observed. Applying the same outflow profile further out within the disk, the resultant effects on the observable CR spectral properties are determined. A hardening in the spectra due to the competition of advective and diffusive propagation within a particular energy range is noted, even in the limiting case of equal CR diffusion coefficients in the disk and halo. It is postulated that this hardening effect may relate to the observed hardening feature in the CR spectrum at a rigidity of $\\approx 200$ GV.

  2. Sea breeze wind field prediction in atmospheric dispersion modelling

    International Nuclear Information System (INIS)

    The estimation of the dispersion of an airborne radioactive release presupposes the knowledge of the windfield and the level of diffusion in the region under consideration. The presence of the sea breeze requires particular attention due to the development of circulation patterns and reduced mixing depths within the boundary layer. The present work constitutes a part of the effort to include the sea breeze capability in the ADREA-I code, a transient three dimensional transport code, and refers specifically to the sea breeze analysis along the Alaskan sea coast. It is shown that the generalized three dimensional k-1 model introduced in ADREA-I, can be also faithfully applied to sea breeze calculations. (author)

    Sea-breeze-deep convective interactions over the Florida peninsula were investigated using a cloud/mesoscale numerical model. The objective was to gain a better understanding of sea-breeze and deep convective interactions over the Florida peninsula using a high resolution convectively explicit model and to use these results to evaluate convective parameterization schemes. A 3-D numerical investigation of Florida convection was completed. The Kuo and Fritsch-Chappell parameterization schemes are summarized and evaluated.

  4. An observational study of sea breeze characteristics over Kalpakkam Coast

    International Nuclear Information System (INIS)

    An observational study of the sea breeze characteristics has been carried out at Kalpakkam, India which lies on the East coast of Southern Indian peninsula about 700 m inland from the sea, the Bay of Bengal. There are clear and significant changes in the surface meteorological parameters at the onset and during sea-breeze phenomenon in the coastal areas. Hourly averaged measurements from a 30 m tall micrometeorological tower were used to study the sea-breeze characteristics at the above site. In this study, based on detailed analysis of the data on-set criteria of the sea breeze is characterized by increase in relative humidity at least by 5%, fall in temperature by equal or greater than 0.5 K and increase in wind speed with respect to previous hour record. The present study is also compared with the earlier studies in relation to sea breeze carried out at Chennai located approximately 80 km North from Kalpakkam and the differences between these studies are discussed. The comparison of sea breeze characteristics of the present study with those from earlier studies that were carried out more than half a century back also reflects the changes due to urbanization and other development activities as well as resulting climatic impacts.

    2011-01-01

    We reformulate the adiabatic inflow-outflow (ADIOS) model for radiatively inefficient accretion flows, treating the inflow and outflow zones on an equal footing. For purely adiabatic flows (i.e., with no radiative losses), we show that the mass flux in each zone must satisfy Mdot ~ R^n with n=1, in contrast to previous work in which 0breezes are possible. When small radiative losses (with fixed efficiency) are included, any centrally injected energy flux is radiated away and the system reverts to a power-law behavior with n < 1, where n falls in a small range determined by the fractional...

    This noise impact assessment study was conducted to determine the compliance of the Kent Breeze Wind Farm and the MacLeod Wind Mill projects with the Ontario Ministry of Environment's (MOE) noise guidelines for wind farms. The wind farms will be constructed next to each other in the regional municipality of Chatham-Kent. Noise sources included the wind turbine generators; the transformer substation; and potential adjustments to the wind turbine generator. Wind turbine noise emissions were adjusted for the site's summer night-time shear. The noise impact assessment evaluated distance requirements, and determined the potential impacts of the planned wind farms. Results of the study indicated that all receptors are compliant with MOE guidelines. The maximum noise emission level for a non-participating receptor at an existing dwelling was 40.0 dB. Acoustic specifications, wind measurement data and calculations of sound pressure levels were included. 4 refs., 7 tabs., 5 appendices.

  18. On Alfven waves in the solar breeze

    International Nuclear Information System (INIS)

    The application to the solar wind motivates the consideration of Alfven waves in a radial background magnetic field and radial mean flow, in two cases, viz., with velocity and magnetic field perturbations along parallels, or also with perturbations along meridians, combined in the radial components of vorticity and electric current. In both cases the same second-order Alfven wave equation is obtained; it has, in general, two singularities. If the mean flow velocity is taken to be a power of radial distance, with exponent other than zero or unity, there is a transition layer. In general there is a second singularity, viz., a critical layer, where the Alfven speed equals the mean flow velocity. There is one exceptional case in which the critical layer does not exist, namely a homogeneous medium, for which the mean flow velocity decays on the inverse square of the radial distance, and then Alfven speed also decays in the same way, so that their ratio is a constant, leading to two possibilities: (i) the ratio is not unity, and the wave equation remains of the second-order; (ii) the wave equation becomes of first-order in the case the mean flow velocity and Alfven speed are equal everywhere, because then the waves can propagate only in one direction. Case (i) corresponds to Alfven waves in the solar breeze. Exact solutions of the wave equations are obtained for all values of the radius, as a single expression for the first-order wave equation, whereas for the second-order wave equation it is possible to obtain solutions for small and large radius; the transition level limits the radius of convergence of one of these solutions, but the two solutions together cover the full range of radial distances. The choices of boundary conditions are discussed and the wavefields plotted vs dimensionless distance for several values of the two dimensionless parameters of the problem, viz., the Alfven number and dimensionless frequency, which appear in one combination only.

  19. The Influence of Soil Moisture, Coastline Curvature, and Land-Breeze Circulations on Sea-Breeze Initiated Precipitation

    Science.gov (United States)

    Baker, David R.; Lynn, Barry H.; Boone, Aaron; Tao, Wei-Kuo; Simpson, Joanne

    2000-01-01

    Idealized numerical simulations are performed with a coupled atmosphere/land-surface model to identify the roles of initial soil moisture, coastline curvature, and land breeze circulations on sea breeze initiated precipitation. Data collected on 27 July 1991 during the Convection and Precipitation Electrification Experiment (CAPE) in central Florida are used. The 3D Goddard Cumulus Ensemble (GCE) cloud resolving model is coupled with the Goddard Parameterization for Land-Atmosphere-Cloud Exchange (PLACE) land surface model, thus providing a tool to simulate more realistically land-surface/atmosphere interaction and convective initiation. Eight simulations are conducted with either straight or curved coast-lines, initially homogeneous soil moisture or initially variable soil moisture, and initially homogeneous horizontal winds or initially variable horizontal winds (land breezes). All model simulations capture the diurnal evolution and general distribution of sea-breeze initiated precipitation over central Florida. The distribution of initial soil moisture influences the timing, intensity and location of subsequent precipitation. Soil moisture acts as a moisture source for the atmosphere, increases the connectively available potential energy, and thus preferentially focuses heavy precipitation over existing wet soil. Strong soil moisture-induced mesoscale circulations are not evident in these simulations. Coastline curvature has a major impact on the timing and location of precipitation. Earlier low-level convergence occurs inland of convex coastlines, and subsequent precipitation occurs earlier in simulations with curved coastlines. The presence of initial land breezes alone has little impact on subsequent precipitation. however, simulations with both coastline curvature and initial land breezes produce significantly larger peak rain rates due to nonlinear interactions.

    Melville, Wayne; Campbell, Todd; Fazio, Xavier; Stefanile, Antonio; Tkaczyk, Nicholas

    2014-10-01

    This article examines the influence of a practicum teaching experience on two pre-service science teachers. The research is focused on examining a practicum in a secondary science department that actively promotes the teaching and learning of science as inquiry. We investigated the process through which the pre-service science teachers integrated their practical knowledge, and examined this in the context of the quantified reformed instruction they enacted. Using a mixed methods design, we have quantified these pre-service science teachers' practice using the Reformed Teaching Observation Protocol (Piburn et al. 2000), in concert with a narrative methodology drawn from in-depth interviews. Our analysis of the data indicates two important conclusions. The first is the importance of a consistently reformed image of science education being presented and practiced by both science teacher educators and cooperating teachers. The second is the recognition that a consistently reformed image may not be sufficient, of itself, to challenge pre-service teachers' views of science education. Pre-service teachers appear to be heavily influenced by their biographies and own science education. Consequently, it appears the extent to which a pre-service teacher identifies problems of teaching and learning, and then works toward possible resolution, influences their progress in shaping reformed views of science education.

  2. Ocean breeze monitoring network at the Oyster Creek Nuclear Plant

    International Nuclear Information System (INIS)

    The Oyster Creek Nuclear Generating Station (OCNGS) is located in New Jersey 10 km west of the Atlantic Ocean. Routine meteorological monitoring at the station has consisted of a single meteorological tower 120 m high and instrumented at the 10-m, 46-m, and 116-m levels. An analysis of 5 yr of data from this tower showed the OCNGS is affected by an ocean breeze ∼ 1 day out of 4 during May through August. This suggested the need for meteorological monitoring in addition to the single met tower at OCNGS. As a result of the 1985 OCNGS meteorological monitoring study, GPU Nuclear established an ocean breeze monitoring network in the fall of 1986. It is a permanent part of OCNGS meteorological monitoring and consists of the same sites as used in the 1985 field study. Meteorological towers are located at the ocean site, the inland site, and at OCNGS. The ocean tower is 13 m (43 ft) high, the inland tower 10 m (33 ft), and the OCNGS tower 116 m (380 ft). Wind speed, wind direction, and temperature are measured on each tower; delta-temperature is also measured on the main tower. The instruments are calibrated in the spring, summer, and fall. The network is operated and maintained by GPU Nuclear Environmental Controls. The ocean breeze monitoring network and meteorological information system forms the basis for including the effects of the ocean breeze in OCNGS emergency off-site dose assessment

    Full Text Available This study investigates the diurnal evolution of sea-breeze rotation over an island in the mid-latitudes. Earlier research on sea-breezes in Sardinia shows that the onshore winds around various coasts of the island exhibit both the theoretically predicted clockwise rotation as well as seemingly anomalous anti-clockwise rotation. A non-hydrostatic fully compressible numerical model (WRF is used to simulate wind fields on and around the island on previously-studied sea-breeze days and is shown to accurately capture the circulation on all coasts. Diurnal rotation of wind is examined and patterns of clockwise and anti-clockwise rotation are identified. A dynamical analysis is performed by extracting individual forcing terms from the horizontal momentum equations. Analysis of several regions around the island shows that the direction of rotation is a result of a complex interaction between near-surface and synoptic pressure gradient, Coriolis and advection forcings. An idealized simulation is performed over an artificial island with dramatically simplified topography, yet similar dimensions and latitude to Sardinia. Dynamical analysis of the idealized case reveals a rather different pattern of hodograph rotation to the real Sardinia, yet similar underlying dynamics. The research provides new insights into the dynamics underlying sea-breeze hodograph rotation, especially in coastal zones with complex topography and/or coastline.

  11. Inclusion of the ocean breeze in Oyster Creek emergency off-site dose assessment

    International Nuclear Information System (INIS)

    The Oyster Creek Nuclear Generating Station (OCNGS) is located 6 mi west of the Atlantic Ocean. From spring through late summer, atmospheric transport in the vicinity of OCNGS is periodically affected by the ocean breeze. The ocean breeze produces large differences in wind direction within the OCNGS emergency planning zone during the morning to evening hours. In addition, trajectory reversals can occur near the ocean breeze front. These two characteristics of the ocean breeze must be taken into account when interpreting results from conventional atmospheric dispersion models. The purpose of the study was to determine the flow characteristics of the ocean breeze and to apply these characteristics to an emergency preparedness implementing procedure (EPIP). The EPIP would be used to determine the radiological plume impact region if an accidental release occurred during an ocean breeze

  12. Simple lake breeze front position technique for off-site dose assessment

    International Nuclear Information System (INIS)

    During a lake/sea breeze an airflow trajectory reversal generally occurs at the leading edge (lake/sea breeze front) of the landward advancing marine air and can significantly affect the use of an off-site dose assessment procedure. Knowledge of the location of the lake/sea breeze front in real time is vital in interpreting the results from a conventional straightline Gaussian off-site dose calculation methodology, which ignores this complex flow pattern. A simple, low-cost technique was developed to estimate the location of the lake/sea breeze front in real time from easily obtainable meteorological parameters recorded at National Weather Service stations. Although this technique was developed for lake breezes occurring near the Wisconsin Public Service Kewaunee nuclear plant, the concept is applicable after site-specific modifications for other lakeshore sites in approximating the location of the lake breeze front

  13. On the occurrence of the Apennine day breezes at Parma

    International Nuclear Information System (INIS)

    From data published by the Meteorological Service of the Italian Air Force, valley breeze cases at Parma airport during summer months of 1972, 1973 and 1974 were examined, in order to determine any effect of the atmospheric thermodynamic stability on the presence of the breezes and to obtain some information about the cross-valley circulation in such conditions. Specific humidity was used for this purpose as an almost conservative tracer. The results show that a valley breeze is present more often when stable layers on the Po valley are absent or, at least, higher than the Apennine divide, when, over there, wind is from the Po valley; if the wind is from Tyrrhenian side, stable layers are less important, but in any case they are unfavourable for valley wind regime. When stable layers are present, the specific humidity at M. Cimone is the same as at some level below or above the stability layer whether the wind there comes from the Po or Tyrrhenian side.

    This work was carried out to understand the mechanisms leading to lofting and large-scale advection of aerosols over the Indian Ocean region due to interaction of the sea breeze with the northeast monsoon winds along the west coast of India. European Centre for Medium-Range Weather Forecasts (ECMWF) wind fields for the months of February and March 1999 were analyzed at various times of day. Intense sea breeze activity was observed at 1200 UT (1730 local time) along the west coast of India with average intensity larger in March than in February. The sea breeze was seen to extend inland deeper in March than in February. Lofting of air observed as high as 800 hPa (approximately 2 km above sea level) could lead to entrainment of aerosols into the free troposphere and long-range transport. Upward motion of air was observed everywhere along the west coast of India (from 8° to 20°N), on average higher in March than in February, because of convergence between the sea breeze and the synoptic-scale flow. A region of intense lofting of air and well-defined convergence was observed along the coast of the Karnataka region (12°-16°N). A simulation with a general circulation model nudged with ECMWF data indicated that the intrusion of marine air masses with low concentrations of organic matter is seen as deep as 64 km inland in the evening (1500 UT). Intrusion of the sea-salt plume is seen to a maximum distance of around 200 km from 1500 until 2300 UT. A well-developed lofted layer of aerosols as high as 3 km was also simulated during sea breeze activity along the west coast of India. The general circulation model simulation shows a clear diurnal evolution of the vertical profile of the aerosol extinction coefficient at Goa but fails to reproduce several features of the lidar observations, for example, the marked diurnal variability of the upper layers between 1 and 3 km. However, the model simulates a diurnal cycle at the surface (0-0.7 km) that is not apparent in lidar

  16. Granulation of coke breeze fine for using in the sintering process

    Full Text Available Coke breeze is the main fuel used in the sintering process. The value of -3+1 mm. represents the most favorable particle size for coke breeze in the sintering process. About 20% of total coke fines (-0.5 mm are produced during different steps of preparation. Introducing these fines during the sintering process proves to be very harmful for different operating parameters. Thus ,this study aims at investigating the production of granules resulting from these fines using molasses as organic binder and its application in sintering of an iron ore. The results showed that the granules having the highest mechanical properties were obtained with 14.5 wt % molasses addition. The sintering experiments were performed by using coke breeze in different shapes (-3+1 mm in size, coke breeze without sieving and coke breeze granules -3+1 mm. The reduction experiments, microscopic structure and X-ray analysis for the produced sinter were carried out. The results revealed that, all sinter properties (such as shatter test, productivity of sinter machine and blast furnace, reduction time and chemical composition for produced sinter by using coke breeze with size -3+1 mm and coke breeze granules were almost the same. The iron ore sinter which was produced by using coke breeze without sieving yielded low productivity for both sinter machine and blast furnace. Furthermore, using coke breeze without sieving in sintering of an iron ore decreases the vertical velocity of sinter machine and increases the reduction time.

  18. A Numerical Study of Sea Breeze and Spatiotemporal Variation in the Coastal Atmospheric Boundary Layer at Hainan Island, China

    Science.gov (United States)

    2016-06-01

    Numerical simulations of sea breezes and the coastal atmospheric boundary layer (ABL) at Hainan Island, China during summer and winter are discussed. The different behaviour of sea breezes and the ABL on the leeward and windward sides of the island are examined, and it is found that offshore flows are more likely to create a strong sea-breeze signature, whereas the process of sea-breeze development under onshore flows is difficult to capture. At the location where the sea-breeze signal is remarkable, the height of the coastal ABL displays an abnormal decrease, corresponding to a transitional point from a continental ABL to a thermal internal boundary layer (TIBL) formed under sea-breeze conditions. This is corroborated by the sudden increase in the water vapour mixing ratio and/or wind speed, indicating the arrival of the sea breeze. Regarding the spatial distribution, the TIBL height decreases abruptly just ahead of the sea-breeze front, and above the cold air mass. When the sea-breeze front occurs with a raised head, a cold air mass is separated from the sea-breeze flow and penetrates inland. This separation is attributed to the interaction between the sea breeze and valley breeze, while the dry airflow entraining to the sea-breeze flow may also partially contribute to this air mass separation.

    2016-05-01

    An experimental field campaign took place in September 2013 near the coastline in the southeastern Campos basin in the island of Mallorca to characterize experimentally the transition between the sea and the land breezes and to further study the successful cases with the corresponding high-resolution numerical simulations. Favorable weather conditions were only found for one episode that comprised a well-formed nocturnal land breeze, followed by the morning transition to sea breeze until noon the next day, when incoming clouds switched off the breeze regime. To analyse this transition between land and sea breezes, the official network of stations is used, supplemented by a portable station close to the shore and soundings of temperature (taken by a captive balloon and remotely controlled multicopter). These data are used to check the goodness of the corresponding simulation at a horizontal resolution of 1 km. Model and observations see similarly both regimes and the transition, showing some differences in the timing and the details in the surface layer. This transient event is analyzed in terms of phases, going consecutively through land breeze, phase previous to the sea breeze, when land heating starts, but it is still colder than the sea, the preparatory phase when the land becomes warmer than the sea, and the development phase when the breeze front progresses inland.

    Sea breeze initiated convection and precipitation is investigated along the east coast of India during the Indian southwest monsoon season. The sea breeze circulations are observed approximately 70 to 80% of the days during the summer months (June to August) along the Chennai coast. Observations of average sea breeze wind speeds are stronger at a rural location as compared to the wind speeds observed inside the urban region of Chennai. The sea breeze circulation is shown to be the dominant mechanism for initiating rainfall during the Indian southwest monsoon season. Roughly 80% of the total rainfall observed during the southwest monsoon over Chennai is directly related to the convection initiated by sea breeze circulation.

  14. Hot Jupiter Breezes: Time-dependent Outflows from Extrasolar Planets

    CERN Document Server

    Owen, James E

    2015-01-01

    We explore the dynamics of magnetically controlled outflows from Hot Jupiters, where these flows are driven by UV heating from the central star. In these systems, some of the open field lines do not allow the flow to pass smoothly through the sonic point, so that steady-state solutions do not exist in general. This paper focuses on this type of magnetic field configuration, where the resulting flow becomes manifestly time-dependent. We consider the case of both steady heating and time-variable heating, and find the time scales for the corresponding time variations of the outflow. Because the flow cannot pass through the sonic transition, it remains subsonic and leads to so-called breeze solutions. One manifestation of the time variability is that the flow samples a collection of different breeze solutions over time, and the mass outflow rate varies in quasi-periodic fashion. Because the flow is subsonic, information can propagate inward from the outer boundary, which determines, in part, the time scale of the...

Because the flow is subsonic, information can propagate inwards from the outer boundary, which determines, in part, the time-scale of the flow variability. This work finds the relationship between the outer boundary scale and the time-scale of flow variations. In practice, the location of the outer boundary is set by the extent of the sphere of influence of the planet. The measured time variability can be used, in principle, to constrain the parameters of the system (e.g. the strengths of the surface magnetic fields).

  18. Lake breezes in the southern Great Lakes region and their influence during BAQS-Met 2007

    Directory of Open Access Journals (Sweden)

    D. M. L. Sills

    2011-08-01

    Full Text Available Meteorological observations from the BAQS-Met field experiment during the summer months of 2007 were integrated and manually analyzed in order to identify and characterize lake breezes in the southern Great Lakes region of North America, and assess their potential impact on air quality. Lake breezes occurred frequently, with one or more lake breezes identified on 90 % of study days. They affected all parts of the study region, including southwestern Ontario and nearby portions of southeast Lower Michigan and northern Ohio, with lake-breeze fronts occasionally penetrating from 100 km to over 200 km inland. Occurrence rates and penetration distances were found to be higher than previously reported in the literature. This comprehensive depiction of observed lake breezes allows an improved understanding of their influence on the transport, dispersion, and production of pollutants in this region.

    The observational analyses were compared with output from subsequent runs of a high-resolution numerical weather prediction model. The model accurately predicted lake breeze occurrence and type in a variety of synoptic wind regimes, but selected cases showed substantial differences in the detailed timing and location of lake-breeze fronts, and with the initiation of deep moist convection. Knowledge of such strengths and weaknesses aids in the interpretation of results from air quality models driven by this meteorological model.

  20. Sea breeze-induced mesoscale systems and severe weather

    Science.gov (United States)

    Pielke, R. A.

    1985-01-01

    The relationship between thunderstorm activity during the summer months along coastal regions of the Atlantic and Gulf coasts and the dry sea breeze circulation was investigated. Satellite composites of thunderstorm activity for synoptically undisturbed conditions have been obtained for south Florida for a series of days in the summer of 1983. These data were catalogued into different low level synoptic flow regimes. Five synoptic flow regimes were found from the data. A three-dimensional mesoscale numerical model was used for each sysnoptic flow regime to quantitatively predict the location of enhanced thunderstorm activity. This model includes a parameterization of vegetation and soil moisture feedbacks as well as a sophisticated planetary boundary layer representation. Using the results of the satellite image composites, spatial and temporal characteristics of deep convective cloud patterns and their variation with synoptic flow are described. The results from the numerical model have provided explanations for the observed patterns.

  1. Interactions between the thermal internal boundary layer and sea breezes

    Energy Technology Data Exchange (ETDEWEB)

    Steyn, D.G. [The Univ. of British Columbia, Dept. of Geography, Atmospheric Science Programme, Vancouver (Canada)

    1997-10-01

    In the absence of complex terrain, strongly curved coastline or strongly varying mean wind direction, the Thermal Internal Boundary Layer (TIBL) has well known square root behaviour with inland fetch. Existing slab modeling approaches to this phenomenon indicate no inland fetch limit at which this behaviour must cease. It is obvious however that the TIBL cannot continue to grow in depth with increasing fetch, since the typical continental Mixed Layer Depths (MLD) of 1500 to 2000 m must be reached between 100 and 200 km from the shoreline. The anticyclonic conditions with attendant strong convection and light winds which drive the TIBL, also drive daytime Sea Breeze Circulations (SBC) in the coastal zone. The onshore winds driving mesoscale advection of cool air are at the core of TIBL mechanisms, and are invariably part of a SBC. It is to be expected that TIBL and SBC be intimately linked through common mechanisms, as well as external conditions. (au)

    Full Text Available This article addresses the role to be performed by the Practicum in the training of social workers. For this purpose we have done a brief tour around the different criteria that have supported the professional development of social education and academic training. It offers thus an epistemological revision has its initial motivation in the need identified in several research projects in which we have participated in over the selection of studies in the early stages of post-compulsory education and compulsory secondary. The analysis of the different actors involved in the process of professionalization of social education and the importance of certain skills, lead us to propose a Practicum able to provide a framework for reflection on professional practices in a learning coordinated context, interdisciplinary and professionalism.

    Coke breeze is the main fuel used in the sintering process. The value of -3+1 mm. represents the most favorable particle size for coke breeze in the sintering process. About 20% of total coke fines (-0.5 mm) are produced during different steps of preparation. Introducing these fines during the sintering process proves to be very harmful for different operating parameters. Thus ,this study aims at investigating the production of granules resulting from these fines using molasses as organ...

  8. Sea Breezes over the Red Sea: Affect of topography and interaction with Desert Convective Boundary Layer

    2014-05-01

    Thermodynamic structure of sea-breeze, its interaction with coastal mountains, desert plateau and desert convective boundary layer have been investigated in the middle region of the Red Sea around 25°N, at the Western coast of Saudi Arabia. Sea and land breeze is a common meteorological phenomenon in most of the coastal regions around the world. Sea-Breeze effects the local meteorology and cause changes in wind speed, direction, cloud cover and sometimes precipitation. The occurrence of sea-breeze, its intensity and landward propagation are important for wind energy resource assessment, load forecasting for existing wind farms, air pollution, marine and aviation applications. The thermally induced mesoscale circulation of sea breeze modifies the desert Planetary Boundary Layer (PBL) by forming Convective Internal Boundary Layer (CIBL), and propagates inland as a density current. The leading edge of the denser marine air rapidly moves inland undercutting the hot and dry desert air mass. The warm air lifts up along the frontal boundary and if contains enough moisture a band of clouds is formed along the sea breeze front (SBF). This study focuses on the thermodynamic structure of sea-breeze as it propagates over coastal rocky mountain range of Al-Sarawat, east of the Red Sea coast, and the desert plateau across the mountain range. Additional effects of topographical gaps such as Tokar gap on the dynamics of sea-land breezes have also been discussed. Interaction of SBF with the desert convective boundary layer provide extra lifting that could further enhance the convective instability along the frontal boundary. This study provides a detailed analysis of the thermodynamics of interaction of the SBF and convective internal boundary layer over the desert. Observational data from a buoy and meteorological stations have been utilized while The Advanced Research WRF (ARW) modeling system has been employed in real and 2D idealized configuration.

  11. Identifying and tracking plumes affected by an ocean breeze in support of emergency preparedness

    International Nuclear Information System (INIS)

    To better support emergency preparedness, General Public Utilities (GPU) Nuclear has investigated the frequency of occurrence of the mesoscale ocean breeze at the Oyster Creek Nuclear Generating Station (OCNGS). Through the analysis of the horizontal wind direction and temperature patterns, simple identification of the ocean breeze along with a plume tracking procedure has been developed and incorporated into the site's emergency plant to better safeguard the public with sophisticated protective action measures in case of a nonroutine release. The ocean breeze will frequently produce wind trajectory fields within the plant's emergency planning zone that are different from the normal gradient wind flow. This could greatly alter proper protective action measures since most utilities employ straight-line trajectory air dispersion models. Knowledge of the existence of the ocean breeze and the location of the ocean breeze front become important in the results generated from the straight-line Gaussian dose calculation methodology and in the further development of a more complex dose assessment model. This paper describes the verification and existence of the sea breeze phenomenon and the incorporation of its effects into the OCNGS emergency plan

    2012-06-01

    Full Text Available The behaviour and characteristics of the marine component of sea breeze cells have received little attention relative to their onshore counterparts. Yet there is a growing interest and dependence on the offshore wind climate from, for example, a wind energy perspective. Using idealized model experiments, we investigate the sea breeze circulation at scales which approximate to those of the Southern North Sea, a region of major ongoing offshore wind farm development. We also contrast the scales and characteristics of the pure and the little known corkscrew and backdoor sea breeze types, where the type is pre-defined by the orientation of the synoptic scale flow relative to the shoreline. We find, crucially, that pure sea breezes, in contrast to corkscrew and backdoor types, can lead to substantial wind speed reductions offshore and that the addition of a second eastern coastline emphasises this effect through generation of offshore "calm zones". The offshore extent of all sea breeze types is found to be sensitive to both the influence of Coriolis acceleration and to the boundary layer scheme selected. These extents range, for example for a pure sea breeze produced in a 2 m s−1 offshore gradient wind, from 10 km to 40 km between the Mellor-Yamada-Nakanishi-Niino and the Yonsei State University schemes, respectively. The corkscrew type restricts the development of a backdoor sea breeze on the eastern coast and is also capable of traversing a 100 km offshore domain even under high gradient wind speed (>15 m s−1 conditions. Realistic variations in sea surface skin temperature during the sea breeze season do not significantly affect the circulation, suggesting that a thermal contrast is only needed as a precondition to the development of the sea breeze. We highlight how sea breeze impacts on circulation need to be considered in order to improve the accuracy of

We present and test an identification method which distinguishes sea-breeze types which can, in principle, be adapted for other coastl...

  10. A theoretical study of the interactions of urban breeze circulation with mountain slope winds

    2015-08-01

    A large number of cities around the world are located in or near complex terrain. In these regions, urban breeze circulation and mountain/valley winds are observed. Understanding interactions between urban breeze circulation and mountain/valley winds is important in a view of mesoscale atmospheric dynamics and urban air pollution. In this study, we theoretically examine the interactions of urban breeze circulation with mountain slope winds in the context of the response of the atmosphere to specified thermal forcing. Starting from linearized governing equations in two dimensions, analytical solutions for perturbation vertical velocity, horizontal velocity, buoyancy, and kinematic pressure are obtained. Then, the analytical solutions are used to examine the interactions. Urban breeze circulation and mountain slope winds evolve with time due to time-varying thermal forcing that has steady and diurnal components, and they interact with each other. Asymmetric flows are developed over the urban and mountain areas. In the daytime, low-level converging flows induced by urban heating (urban breeze) and those induced by mountain heating (upslope winds) interfere with each other, resulting in weakened flows in the mountain-side urban area and on the urban-side mountain slope. The transition from the upslope wind to downslope wind on the urban-side mountain slope occurs earlier and thus the downslope wind persists longer compared with the case that has mountain thermal forcing only. In the nighttime, flows become strong in the region between the urban center and the mountain center due to the additive interaction of the downslope wind with the urban breeze, but the flow intensity weakens with time because of weak nighttime urban heating. In the nighttime, converging flows on the plain-side urban area and the downslope wind on the rural-side mountain slope are weakened. The degree of the interactions of urban breeze circulation with mountain slope winds is shown to depend on

  11. Numerical study of the evolution of a sea-breeze front under two environmental flows

    Science.gov (United States)

    Liang, Zhaoming; Wang, Donghai

    2015-06-01

    The evolution of a sea-breeze front (SBF) in parallel and offshore environmental flows was investigated by using high-resolution simulations of two SBF cases from the Bohai Bay region, China. The results show that the combination of a distinct vertical wind shear caused by the sea-breeze circulation with a neutral or slightly stable atmospheric stratification associated with the thermal inner boundary layer promoted the occurrence and maintenance of a Kelvin-Helmholtz billow (KHB). In a parallel environmental flow, the SBF evolved into a few connected segments because of the inhomogeneity of the sea-breeze direction and intensity as it penetrated inland. A significant upward vertical motion occurred at the two ends of the SBF segment owing to the sea-breeze convergence and was accelerated by the KHB. The KHB made a notable contribution to the intensity at the ends of the segment, whereas the intensity at the middle segment was primarily attributed to the convergence between the sea breeze and the parallel flow. In the offshore environmental flow, the clockwise rotation of the offshore flow varying with time increased the downstream convergence of the interface between the sea breeze and the offshore flow and pushed the downstream convergence zone to an orientation consistent with the offshore flow. The air parcels ascending from the downstream part of the SBF were continuously lifted by the downstream convergence zone during their advection, leading to a significant downstream development of the SBF. The significant upward vertical motion caused by the sea-breeze convergence behind the upstream end of the SBF was shifted to the upstream end of the SBF by the KHB, which enhanced the intensity of the upstream end of the SBF.

    We investigate the signals from neutral helium atoms observed in situ from Earth orbit in 2010 by the Interstellar Boundary Explorer (IBEX). The full helium signal observed during the 2010 observation season can be explained as a superposition of pristine neutral interstellar He gas and an additional population of neutral helium that we call the Warm Breeze. The Warm Breeze is approximately 2 times slower and 2.5 times warmer than the primary interstellar He population, and its density in front of the heliosphere is ∼7% that of the neutral interstellar helium. The inflow direction of the Warm Breeze differs by ∼19° from the inflow direction of interstellar gas. The Warm Breeze seems to be a long-term, perhaps permanent feature of the heliospheric environment. It has not been detected earlier because it is strongly ionized inside the heliosphere. This effect brings it below the threshold of detection via pickup ion and heliospheric backscatter glow observations, as well as by the direct sampling of GAS/Ulysses. We discuss possible sources for the Warm Breeze, including (1) the secondary population of interstellar helium, created via charge exchange and perhaps elastic scattering of neutral interstellar He atoms on interstellar He{sup +} ions in the outer heliosheath, or (2) a gust of interstellar He originating from a hypothetic wave train in the Local Interstellar Cloud. A secondary population is expected from models, but the characteristics of the Warm Breeze do not fully conform to modeling results. If, nevertheless, this is the explanation, IBEX-Lo observations of the Warm Breeze provide key insights into the physical state of plasma in the outer heliosheath. If the second hypothesis is true, the source is likely to be located within a few thousand AU from the Sun, which is the propagation range of possible gusts of interstellar neutral helium with the Warm Breeze characteristics against dissipation via elastic scattering in the Local Cloud.

    Doppler radar derived wind speed and direction profiles showed a well developed sea breeze circulation over the Chennai, India region on 28 June, 2003. Rainfall totals in excess of 100 mm resulted from convection along the sea breeze front. Inland propagation of the sea breeze front was observed in radar reflectivity imagery. High-resolution MM5 simulations were used to investigate the influence of Chennai urban land use on sea breeze initiated convection and precipitation. A comparison of observed and simulated 10 m wind speed and direction over Chennai showed that the model was able to simulate the timing and strength of the sea breeze. Urban effects are shown to increase the near surface air temperature over Chennai by 3.0 K during the early morning hours. The larger surface temperature gradient along the coast due to urban effects increased onshore flow by 4.0m s−1. Model sensitivity study revealed that precipitation totals were enhanced by 25 mm over a large region 150 km west of Chennai due to urban effects. Deficiency in model physics related to night-time forecasts are addressed.

    2015-08-01

    A high-resolution large-eddy simulation (LES) has been performed to simulate a sea-breeze circulation over an idealized peninsular domain. The simulation is forced with the surface latent/sensible heat fluxes and the large-scale horizontal pressure gradient that are obtained from a mesoscale simulation. This methodology allows the investigation of the physical phenomena that are peculiar for a sea-breeze circulation and that generally require spatial resolution approximately equal to 100 m or less. Here, small-scale dynamical effects associated to these phenomena, i.e. the interaction between the sea-breeze front with the convective turbulence generated over-land, the formation of the zero-velocity layer, and the development of the Kelvin-Helmholtz billows, are investigated. Results from the present numerical study have revealed the formation of a zero-velocity layer that is initially near the ground then it rises to define a well-marked sea-breeze depth. Scaling analysis applied to the LES output fields reveals that during the phase of inland penetration the scaling laws for sea-breeze strength and depth have both a proportionality coefficient equal to 0.15.

    2011-02-01

    Full Text Available Mesoscale observations from the BAQS-Met field experiment during the summer of 2007 were integrated and manually analyzed in order to identify and characterize lake breezes in the southern Great Lakes region of North America, and assess their potential impact on air quality. Lake breezes were found to occur on 90% of study days, often occurring in conditions previously thought to impede their development. They affected all parts of the study region, including southwestern Ontario and nearby portions of southeast Michigan and northern Ohio, occasionally penetrating inland from 100 km to over 200 km. Occurrence rates and penetration distances were found to be higher than previously reported in the literature. This more accurate depiction of observed lake breezes allows a better understanding of their influence on the production and transport of pollutants in this region.

    The observational analyses were compared with output from subsequent runs of a high-resolution numerical weather prediction model. The model accurately predicted lake breeze occurrence in a variety of synoptic wind regimes, but selected cases showed substantial differences in the detailed timing and location of lake-breeze fronts, and with the initiation of deep moist convection. Knowledge of such strengths and weaknesses will assist with interpretation of results from air quality modelling driven by this meteorological model.

    We investigate the signals from neutral He atoms observed from Earth orbit in 2010 by IBEX. The full He signal observed during the 2010 observation season can be explained as a superposition of pristine neutral interstellar He gas and an additional population of neutral He that we call the Warm Breeze. The Warm Breeze is approximately two-fold slower and 2.5 times warmer than the primary interstellar He population, and its density in front of the heliosphere is ~7% that of the neutral interstellar helium. The inflow direction of the Warm Breeze differs by ~19deg from the inflow direction of interstellar gas. The Warm Breeze seems a long-term feature of the heliospheric environment. It has not been detected earlier because it is strongly ionized inside the heliosphere, which brings it below the threshold of detection via pickup ion and heliospheric backscatter glow observations, as well as by the direct sampling of GAS/Ulysses. Possible sources for the Warm Breeze include (1) the secondary population of inters...

    The interactions of urban breeze circulation with mountain slope winds are theoretically examined in a linear system that includes mountain mechanical forcing and non-zero basic-state wind. Flows induced by urban thermal forcing, mountain thermal forcing, and mountain mechanical forcing are linearly superposed. Thermally induced asymmetric circulations in the presence of non-zero basic-state wind result in distinct flow patterns depending on the location of the urban area relative to the mountain area. In the cases of the urban area being located on the downstream of the mountain area, strong positive near-surface horizontal wind induced by urban heating interacts with diverging (converging) flow from the mountain area in the nighttime (daytime). In the cases with the urban area being located on the upstream of the mountain area, strong positive near-surface horizontal wind is restricted in the urban area. Mountain mechanical forcing enhances downslope winds on the both sides of the mountain and updraft (downdraft) upstream (downstream) of the mountain. Sensitivities of the interactions to mountain height and basic-state wind speed are also examined. The vertical flux of horizontal momentum is analyzed by dividing the total momentum flux into five components. While terms that are related to flow induced by urban heating are dominant in the daytime, interaction terms that are related to flows induced by two thermal sources and by thermal and mechanical sources play important roles over the rest of times. Moreover, the total momentum flux is dependent on the location of the urban area relative to the mountain area and basic-state wind speed.

Feedback from participants indicated substantial benefit from the training. Many of the participants expressed a desire to present such training to others at their home facilities.

  2. A Numerical Simulation Model of Land and Sea Breezes on the Sir te Gulf, Libya

    International Nuclear Information System (INIS)

    A numerical model is developed in order to simulate land and sea breeze phenomenon in the Gulf of Sirte, which is located on the Libyan coastline. A Mixed-layer Model is used to simulate land and sea breezes and their effect on the coastal strip. The model consists of three layers: the surface layer, the mixed layer and the stable layer. The primitive equations are averaged in the mixed layer to yield predictions equations for the horizontal components of the wind, two componenets of the horizontal pressure gradient, potential temperature of the mixed layer, the height of the base of the overlying stable layer and the surface temperature. The results show that the model is successful in simulating land and sea breezes and making clear the difference between the influence of onshore and offshore winds on the coastal strip. (author)

  5. Study of the sea and land breeze circulation over Trombay using measured and modeled data

    International Nuclear Information System (INIS)

    In this study, the focus is to estimate aspects of sea/land breeze circulation (SLBC) using the coupled WRF-CALMET model for Trombay site within which Bhabha Atomic Research Centre is located. The results are also compared with the SODAR data measured at the site. The domain used in the study is centered on Mumbai, Bhabha Atomic Research Centre, Trombay, is located on the eastern side of Mumbai. Arabian Sea provides a continuous coastline on the western side. Trombay site is surrounded by Thane creek on the east and a 2 km long hill on the west, rendering complexity to the site configuration. SODAR is located at Bhabha Atomic Research Centre close to the 125 m hill on its northern side. The 15 minutes averaged wind data from SODAR was plotted to estimate the time of onset of SLBC. To simulate SLBC, the output from WRF model was coupled to the diagnostic model CALMET for the domain with a grid resolution of 90 m. Simulations were carried out for three days, 16-18, of January 2012. The variation could be attributed to the presence of hill in the proximity of the instrument which reflects the wind in the lower heights and renders complex pattern. But after 13:30 IST, the wind is predominantly from northwest at all heights indicating the onset of sea breeze and remains the same till 22:30 IST when the wind slowly turns to northerly or northeasterly again. This indicates land breeze. From the discussion above, it can be concluded that the onset, duration and cessation of sea breeze for Bhabha Atomic Research Centre site is at 13:30 IST, 9 hrs and 22:00 IST respectively during the study period. Furthermore, the results from WRF-CALMET coupled simulation was also verified by the observed data at site confirming the conclusions derived. The land/sea breeze shifts to sea/land breeze through north direction during the period of study

    Two-dimensional numerical simulations of sea breeze development over a large sandbar on the North Sea coast of Germany are reported. The numerical model used in these experiments contains a detailed treatment of soil moisture, which allows evaluation of the effects of differential surface characteristics on the airflow pattern. Results of the simulations indicate that the contrast between the moist sandbar and adjacent dry land, the tidal inundation of the sandbar, and the westward penetration of the Baltic sea breeze play important roles in the development of mesoscale airflow patterns in the sandbar region.

    1985-01-01

    Model scaling of the characteristics of the sea breeze circulation involved with circular and slab elongated-symmetric midlatitude islands was performed. Larger horizontal and vertical velocities were indicated over the small circular islands as compared to those over corresponding elongated islands. The circulation characteristics of both types of islands become similar when the half-width of the island is about the same as the distance of inland penetration of the sea breeze in a nonisland case. Evaluation of the results through a scale analysis is presented.

    Full Text Available Nursing students begin to complete practicum experiences during their first year, increasing the number of applied credits as they progress toward degree completion. This contributes to integrating knowledge and skills from all of their courses and to obtaining the basic competencies of the nursing profession. It is also essential to identify the student’s sources of stress in order to provide strategies to confront them and diminish the potential consequences. Therefore, it is a priority to ascertain the perception of stress and the stressors. This study applied both quantitative and quality methods to achieve its objectives: to analyze the perception of stress and the stress-generating factors faced by third- and fourth-year nursing students during the mental health practicum, and to determine satisfaction with the new mental health practicum in a student survey and in a focus group of mentor nurses. Study results identified four major stress factors before students began the practicum: the difficulty of providing nursing care for the patient with a mental disorder, knowing how to react in an unfamiliar situation, lack of knowledge about mental health services, and the possibility of patient aggression. Only the latter remained as a stressor after the practicum was completed. Student satisfaction with the mental health practicum was highly positive. Mentor nurses were particularly satisfied with the changes in student follow-up and evaluation, emphasizing the importance of reflective practice and students’ self-management of their learning experience as set out by the European Higher Education Area.

    After withdrawal of the Indian Summer Monsoon and until onset of the next monsoon,i.e.,roughly during November-May, winds in the coastal regions of India are dominated by sea breeze.It has an impact on the daily cycle of the sea state near the coast.The impact is quite significant when large scale winds are weak.During one such event,1 –15 April 1997,a Datawell directional waverider buoy was deployed in 23 m water depth off Goa,west coast of India.Twenty-minute averaged spectra,collected once every three hours,show that the spectrum of sea-breeze-related ‘wind-seas’ peaked at 0.23 ± 0.05 Hz. These wind-seas were well separated from swells of frequencies less than 0.15 Hz.The TMA spectrum (Bouws et al 1985) matched the observed seas spectra very well when the sea-breeze was active and the fetch corresponding to equilibrium spectrum was found to be 77 ± 43 km during such occasions. We emphasize on the diurnal cycle of sea-breeze-related sea off the coast of Goa and write an equation for the energy of the seas as a function of the local wind.

    Meteorological and air-quality model simulations are analyzed alongside observations to investigate the role of the Chesapeake Bay breeze on surface air quality, pollutant transport, and boundary layer venting. A case study was conducted to understand why a particular day was the only one during an 11-day ship-based field campaign on which surface ozone was not elevated in concentration over the Chesapeake Bay relative to the closest upwind site and why high ozone concentrations were observed aloft by in situ aircraft observations. Results show that southerly winds during the overnight and early-morning hours prevented the advection of air pollutants from the Washington, D.C., and Baltimore, Maryland, metropolitan areas over the surface waters of the bay. A strong and prolonged bay breeze developed during the late morning and early afternoon along the western coastline of the bay. The strength and duration of the bay breeze allowed pollutants to converge, resulting in high concentrations locally near the bay-breeze front within the Baltimore metropolitan area, where they were then lofted to the top of the planetary boundary layer (PBL). Near the top of the PBL, these pollutants were horizontally advected to a region with lower PBL heights, resulting in pollution transport out of the boundary layer and into the free troposphere. This elevated layer of air pollution aloft was transported downwind into New England by early the following morning where it likely mixed down to the surface, affecting air quality as the boundary layer grew.

  16. Land-lake breezes at low latitudes: The case of Tonle Sap Lake in Cambodia

    Science.gov (United States)

    Tsujimoto, Kumiko; Koike, Toshio

    2013-07-01

    Tonle Sap Lake is the largest freshwater lake in Southeast Asia. During the postmonsoon season, a small linear cloud system has been observed over this lake in early morning, while the sky above the surrounding land is clear. Although this cloud system is apparently generated by land breezes, previous studies on land-lake (sea) circulation have suggested that environmental factors at low latitudes inhibit development of nocturnal land breezes. In this study, we investigate the mechanism of these early morning clouds through numerical simulation. The simulations show a linear updraft system over the lake, forming along the southwest lakeshore around 22:00 and moving northeast to the middle of the lake. The heavier air mass from the land meets the extraordinarily warm and humid air mass over the lake, triggering updrafts under the conditionally convective instability. The characteristic high surface water temperature was favorable for generation of the land breeze and updraft systems. That high surface water temperature of the lake is produced by the tropical climate along with efficient energy absorption because of the shallowness of the water body. This unique feature can generate a clear nocturnal land breeze circulation accompanying a migrating updraft system over the lake despite its low latitude.

    Surface ozone (O3) was analyzed to investigate the role of the bay breeze on air quality at two locations in Edgewood, Maryland (lat: 39.4deg, lon: -76.3deg) for the month of July 2011. Measurements were taken as part of the first year of NASA's "Deriving Information on Surface Conditions from Column and Vertically Resolved Observations Relevant to Air Quality" (DISCOVER-AQ) Earth Venture campaign and as part of NASA's Geostationary for Coastal and Air Pollution Events Chesapeake Bay Oceanographic campaign with DISCOVER-AQ (Geo-CAPE CBODAQ). Geo-CAPE CBODAQ complements DISCOVER-AQ by providing ship-based observations over the Chesapeake Bay. A major goal of DISCOVER-AQ is determining the relative roles of sources, photochemistry and local meteorology during air quality events in the Mid-Atlantic region of the U.S. Surface characteristics, transport and vertical structures of O3 during bay breezes were identified using in-situ surface, balloon and aircraft data, along with remote sensing equipment. Localized late day peaks in O3 were observed during bay breeze days, maximizing an average of 3 h later compared to days without bay breezes. Of the 10 days of July 2011 that violated the U.S. Environmental Protection Agency (EPA) 8 h O3 standard of 75 parts per billion by volume (ppbv) at Edgewood, eight exhibited evidence of a bay breeze circulation. The results indicate that while bay breezes and the processes associated with them are not necessary to cause exceedances in this area, bay breezes exacerbate poor air quality that sustains into the late evening hours at Edgewood. The vertical and horizontal distributions of O3 from the coastal Edgewood area to the bay also show large gradients that are often determined by boundary layer stability. Thus, developing air quality models that can sufficiently resolve these dynamics and associated chemistry, along with more consistent monitoring of O3 and meteorology on and along the complex coastline of Chesapeake Bay must be a

  1. The effect of coastal upwelling on the sea-breeze circulation at Cabo Frio, Brazil: a numerical experiment

    Directory of Open Access Journals (Sweden)

    S. H. Franchito

    Full Text Available The effect of coastal upwelling on sea-breeze circulation in Cabo Frio (Brazil and the feedback of sea-breeze on the upwelling signal in this region are investigated. In order to study the effect of coastal upwelling on sea-breeze a non-linear, three-dimensional, primitive equation atmospheric model is employed. The model considers only dry air and employs boundary layer formulation. The surface temperature is determined by a forcing function applied to the Earth's surface. In order to investigate the seasonal variations of the circulation, numerical experiments considering three-month means are conducted: January-February-March (JFM, April-May-June (AMJ, July-August-September (JAS and October-November-December (OND. The model results show that the sea-breeze is most intense near the coast at all the seasons. The sea-breeze is stronger in OND and JFM, when the upwelling occurs, and weaker in AMJ and JAS, when there is no upwelling. Numerical simulations also show that when the upwelling occurs the sea-breeze develops and attains maximum intensity earlier than when it does not occur. Observations show a similar behavior. In order to verify the effect of the sea-breeze surface wind on the upwelling, a two-layer finite element ocean model is also implemented. The results of simulations using this model, forced by the wind generated in the sea-breeze model, show that the sea-breeze effectively enhances the upwelling signal.

    A comprehensive field experiment devoted to the study of coastal processes on a micro-tidal beach was conducted from March 30th to April 12th 2014 in Sisal, Yucatán México. Wave conditions in the study area are controlled by local (i.e., sea-breezes) and meso-scale (i.e., Nortes) meteorological events. Simultaneous measurements of waves, tides, winds, currents, sediment transport, runup, and beach morphology were obtained in this experiment. Very dense nearshore instrumentation arrays allow us the study of the cross-/along- shore variability of surf/swash zone dynamics during different forcing conditions. Strong sea-breeze wind events produced a diurnal cycle with a maximum wind speed of 14 m/s. The persistent sea-breeze system forces small-amplitude (Hs1 m) Norte event, lasting 48 hours, reached the coast on April 8th generating a long-period swell (Tp>10 s) arriving from the NNW. This event induced an eastward net sediment transport across a wide surf zone. However, long-term observations of sand impoundment at a groin located near the study area suggests that the net sediment transport in the northern Yucatan peninsula is controlled by sea-breeze events and hence swash zone dynamics play an important role in the net sediment budget of this region. A comparative study of surf and swash zone dynamics during both sea-breeze and Norte events will be presented.

    Internal wave propagation and water column mixing phenomena play an important role in many marine ecosystem coastal process. In Northern Tyrrhenian coast the experimental proposed approach is aimed to identify these type of oscillation in presence of breeze circulation. Along the Tyrrhenian coast summer period climate conditions allow the generations of high frequency land-sea breeze events. This local circulation, land-sea breeze indeed, may generate significant modifications of the sea waters physical parameters. Thay often appear as internal gravity waves especially in presence of stratified water and stable thermocline. Since the whole investigated process evolves on diurnal scale and in the space of a few miles the sampling plan was operated with a series of oceanographic surveys at 40 meters depth with 20 minutes interval one from another between 5 a.m. and 11 a.m. and they were repeted during each summers between 2012 - 2014. Coupled with the acquisition of physical parameters current data were collected with 500 kHz ADCP every 20s, the resolution of vertical profiles of CTD matches the ADCP 1 meter magnitude vertical resolution. in order to investigate the water column layers dynamics behavior, Brunt-Vaisala and Richardson number were computed using the sampled physical parameters. Coastal surveys analysis highlights the presence of temperature oscillation in proximity of the thermocline and bottom layers; these oscillations have been observed during all measure surveys, when the land breeze was over. Indeed the land breeze tends to generate an offshore transport causing bottom layers to lift. At the same time solar radiation heating causes a sink of the surface layers which flatten the layers in proximity of the thermocline. Therefore the oscillations of temperature observed during the oceanographic surveys have to considered as internal waves, as during earlier studies conducted in the Tyrrhenian Sea has been observed.

    Executive Summary Renewable Energy Initiatives for Clark County Parks and Recreation Solar Project DOE grant # DE-EE0003180 In accordance with the goals of the Department of Energy (DOE) Office of Energy Efficiency and Renewable Energy for promoting solar energy as clean, carbon-free and cost-effective, the County believed that a recreational center was an ideal place to promote solar energy technologies to the public. This project included the construction of solar electricity generation facilities (40kW) at two Clark County facility sites, Desert Breeze Recreational Center and Hollywood Recreational Center, with educational kiosks and Green Boxes for classroom instruction. The major objectives and goals of this Solar Project include demonstration of state of the art technologies for the generation of electricity from solar technology and the creation of an informative and educational tool in regards to the benefits and process of generating alternative energy. Clark County partnered with Anne Johnson (design architect/consultant), Affiliated Engineers Inc. (AEI), Desert Research Institute (DRI), and Morse Electric. The latest photovoltaic technologies were used in the project to help create the greatest expected energy savings for60443 each recreational center. This coupled with the data created from the monitoring system will help Clark County and NREL further understand the real time outputs from the system. The educational portion created with AEI and DRI incorporates material for all ages with a focus on K - 12. The AEI component is an animated story telling the fundamentals of how sunlight is turned into electricity and DRI‘s creation of Solar Green Boxes brings environmental education into the classroom. In addition to the educational component for the public, the energy that is created through the photovoltaic system also translates into saved money and health benefits for the general public. This project has helped Clark County to further add to its own

    Full Text Available A numerical study of the development and structure of the sea breeze in Mallorca is presented using a meso- numerical model. The model includes a detailed representation of the soil and vegetation processes. The study covers a diurnal cycle. The results show that the model reproduces the main known features of the circulation and new ones appear, which seem to have an appreciable effect on the circulation during the decay of the sea breeze. The orography and soil dryness have been identified as the main factors determining the structure of the breeze. Three more experiments have been performed in order to isolate the effect of each factor.

    2016-01-01

    Full Text Available The paper suggests a new method of implementing an activity approach in a physicsoriented program. Such method implies the use of a system which comprises three types of practical sessions: a laboratory practicum, a practical training aimed at analyzing physical processes on the basis of computerized modeling and a problem-solving practicum. A methodology used for holding practicums provides for an active use of information technologies. At laboratory sessions we use computerized sensors, tablets with an integrated data recorder, an electronic oscilloscope and process data in Excel tables. At practicums aimed at analyzing physical processes, we develop programs in Visual Basic and Рascal in order to visualize physical processes in the form of motion trajectories, dynamic charts; besides, we conduct computer experiments. At problem-solving practicums we use our own PowerPoint “Study Guide for an Interactive Whiteboard”, which contains a database of graphic and pictorial physics problems for students of 10–11 grades. Knowledge of information technologies facilitates students’ adaptation in modern society, improves education quality.

    The 2003-2006 observations were utilized to analyze the surface characteristics of summer land-sea breezes along the coastland of Guangxi and the Weather Research and Forecast model was applied to simulate the breeze structure on August 1-2,2006.Results show that 1)the intensity and distributions of the breezes reproduced from improved urban underlying surface were close to observations.In the daytime the coastwise urban band was a convergent belt of sea breeze,corresponding to the centers of torrential rains; in the nighttime hours the surface of the Gulf of Tonkin(the Vietnamese name)or the Northern Bay(the Chinese name)acted as a convergent zone of land breezes,likely to produce convectivecloud cluster; 2)the experiment on urbanization showed the heat island effect enhancing(weakening)the sea(land)breeze development.Furthermore,the heat island effect mitigated the atmospheric cooling viaradiation over the cities in the night,weakening sinking motion correspondingly,thereby suppressing the dominant factor responsible for the steady development of temperature inversion.As a result,the inversion vigor was reduced greatly,but nevertheless no strong effect of the decreased subsidence was found upon the inversion height.

  15. A climatological study of sea breeze clouds in the southeast of the Iberian Peninsula (Alicante, Spain)

    Sea breezes blow under anticyclonic weather types, weak surface pressure gradients, intense solar radiation and relatively cloud-free skies. Generally, total cloud cover must be less than 4/8 in order to cause a thermal and pressure difference between land and sea air which allows the development of this local wind circulation. However, many numerical and observational studies have analyzed the ability of sea breezes to generate clouds in the convective internal boundary layer and in the sea breeze convergence zone. Accordingly, the aim of this study is to statistically analyze the impact of sea breezes on cloud types in the convective internal boundary layer and in the sea breeze convergence zone. The study area is located in the southeast of the Iberian Peninsula (province of Alicante, Spain) and the survey corresponds to a 6-yr study period (2000-2005). This climatological study is mainly based on surface cloud observations at the Alicante-Ciudad Jardin station (central coastal plain) and on an extensive cloud observation field campaign at the Villena-Ciudad station (Prebetic mountain ranges) over a 3-yr study period (2003-2005). The results confirm the hypothesis that the effect of sea breezes on cloud genera is to increase the frequency of low (Stratus) and convective (Cumulus) clouds. Sea breezes trigger the formation of thunderstorm clouds (Cumulonimbus) at the sea breeze convergence zone, which also have a secondary impact on high-level (Cirrus, Cirrocumulus, Cirrostratus), medium-level (Altostratus, Altocumulus) and low-level clouds (Stratus, Stratocumulus, Nimbostratus) associated with the Cumulonimbus clouds (e.g., Cumulonimbus anvil).

  16. A simplified method to compute radionuclide concentrations under sea breeze situations

    International Nuclear Information System (INIS)

    The objective of this paper is to present an alternate method to compute ground-level radionuclide concentrations for the use under emergency conditions at a coastal nuclear power plant for sea breeze cases. The method involves the use of a work sheet and graphs. The results are compared with the EPA method given in ''Manual of Protective Action Guides and Protective Actions for Nuclear Incidents.'' A method has been developed to predict ground-level concentrations of radionuclides under sea-breeze conditions. Using the procedure outlined in this report in conjunction with Figures 2-9, an estimate of concentration/dose for Xe-133 and I-131 versus downwind distance can be obtained quickly. A comparison of the data from this study and the currently recommended EPA procedures shows a large discrepancy between the two methods and indicates a need for their revision

  17. Behavior of the land and sea breeze at the KUR site and its environs

    International Nuclear Information System (INIS)

    The land and sea breeze(LSB) is one of the controlling factors for the atmospheric dispersion of radioactive effluents released from the Kyoto University Reactor(KUR) facilities. Behavior of the LSB at the KUR site and its environs is analyzed by using the wind data from the AMeDAS stations of the Japan Meteorological Agency located in the area surrounding Osaka Bay. The so-called large-scale sea breeze from the Kii Channel, existence of which has been conjectured from a rather small amount of data, is clearly seen from the diurnal variation of wind direction observed simultaneously at the two stations, one is in the Osaka plain and the other at Awaji Island. The diurnal course of the LSB occurring in the water body including Osaka Bay and the Kii Channel and its surrounding land body is deduced from the analysis. (author)

  18. Association of non-marine sulfate aerosol with sea breeze circulation in Tampa bay

    International Nuclear Information System (INIS)

    Peak concentrations of aerosol sulfur in Tampa, Florida may be the result of either regional-scale transformation and transport processes or local-scale transport from nearby air pollution sources. The existence of the latter has been demonstrated in Tampa through correspondence of sulfur with sea breeze circulation patterns and the resulting chloride concentration maxima (which serve as indicators of the marine aerosol), vanadium concentration maxima (which indicate times of high concentrations of certain plume constituents), and the locations of sources favorable for high concentrations of air pollution-derived sulfate during occurrences of the sea breeze. The analysis indicates that locally derived sulfate in the Tampa atmosphere, which may be less abundant than sulfate due to regional-scale processes, can be identified by the use of combined meteorological and chemical tracer interpretation

  20. An observational study of land and sea breezes in the southern part of the Osaka district

    International Nuclear Information System (INIS)

    Detailed observations of the wind and temperature profiles in land and sea breeze situations were made in the southern part of the Osaka district by using pilot-balloon with double-theodolite method and lower-troposphere-radiosonde in the summer from 1981 to 1983. Diurnal course of the wind system observed is as follows. In the morning and early afternoon, an onshore flow from Osaka Bay is observed within several hundred meters height above the ground surface. The depth of the flow tends to thicken with elapse of time. In the late afternoon and evening, a flow parallel to the coastline and blowing from the Kii channel prevails in the first thousand meters layer of the atmosphere, which shows, in the middle of the period, the characteristics of the nocturnal low-level jet. After midnight until dawn, a flow having the reverse direction to the former appears in a few hundred meters layer of the atmosphere. A flow pertinent to the land/mountain breeze in the area under study appears only in the lowest several tens of meters layer of the atmosphere. A decrease in wind speed by a few meters a second and a veering in wind direction by about 10 degrees are seen in the first few hundred meters layer of the atmosphere between coast and several kilometers inland in the sea breeze situation, suggesting modification of the sea breeze during travel over land. Diurnal change of the temperature field below 3000 meters height above the ground surface observed by serial ascents of lower-troposphere-radiosondes is also discussed. (author)

  1. Land Surface Data Assimilation and the Northern Gulf Coast Land/Sea Breeze

    A technique has been developed for assimilating GOES-derived skin temperature tendencies and insolation into the surface energy budget equation of a mesoscale model so that the simulated rate of temperature change closely agrees with the satellite observations. A critical assumption of the technique is that the availability of moisture (either from the soil or vegetation) is the least known term in the model's surface energy budget. Therefore, the simulated latent heat flux, which is a function of surface moisture availability, is adjusted based upon differences between the modeled and satellite observed skin temperature tendencies. An advantage of this technique is that satellite temperature tendencies are assimilated in an energetically consistent manner that avoids energy imbalances and surface stability problems that arise from direct assimilation of surface shelter temperatures. The fact that the rate of change of the satellite skin temperature is used rather than the absolute temperature means that sensor calibration is not as critical. The sea/land breeze is a well-documented mesoscale circulation that affects many coastal areas of the world including the northern Gulf Coast of the United States. The focus of this paper is to examine how the satellite assimilation technique impacts the simulation of a sea breeze circulation observed along the Mississippi/Alabama coast in the spring of 2001. The technique is implemented within the PSU/NCAR MM5 V3-4 and applied on a 4-km domain for this particular application. It is recognized that a 4-km grid spacing is too coarse to explicitly resolve the detailed, mesoscale structure of sea breezes. Nevertheless, the model can forecast certain characteristics of the observed sea breeze including a thermally direct circulation that results from differential low-level heating across the land-sea interface. Our intent is to determine the sensitivity of the circulation to the differential land surface forcing produced via the

    The frequency, the location and the characteristics of convective rainfall events induced by the convergence of different sea breeze systems on a Mediterranean peninsula (Salento, in southeastern Italy) are analyzed. Such events have been studied considering satellite/radar images and output fields from two Limited Area Models in the summer period of 2011-2013. A total of 20 days have been detected in which the precipitation due to sea-breeze convergence was clearly observed in satellite and radar images. The synoptic conditions associated with these events have been identified considering the averages of some relevant meteorological parameters in the selected days and the anomaly with respect to the climate. The presence of a cold trough in the central Mediterranean basin appears as a fundamental ingredient for the occurrence of sea breeze convergence and associated precipitation. High-resolution simulations with two state-of-art numerical models have revealed that both of them are generally able to simulate a convergence pattern correctly, apart from a couple of cases for each model. The higher rainfall amounts occur with weak synoptic wind, and weak-to-moderate values of Convective Available Potential Energy (CAPE). When the synoptic wind is of moderate intensity, the region of convergence moves toward the Adriatic coast for a prevailing southerly component, and toward the Ionian coast for a prevailing northerly component. On the opposite, the skin sea surface temperature is relatively uniform and the difference between the Ionian and the Adriatic Seas, surrounding the peninsula on the east and west side, is generally smaller than 1 K, having only a marginal effect on the sea breeze patterns. Similarly, the value of CAPE before the occurrence of rainfall has low prognostic value. The results shows that limited area models with a grid spacing of few km appear as appropriate tools for the simulation for such relatively small scale phenomena.

    2011-01-01

    In this paper we examine the variations of the boreal summer season sea breeze circulation along the Florida panhandle coast from relatively high resolution (10 km) regional climate model integrations. The 23 year climatology (1979–2001) of the multidecadal dynamically downscaled simulations forced by the National Centers for Environmental Prediction–Department of Energy (NCEP-DOE) Reanalysis II at the lateral boundaries verify quite well with the observed climatology. The variations at diurnal and interannual time scales are also well simulated with respect to the observations. We show from composite analyses made from these downscaled simulations that sea breezes in northwestern Florida are associated with changes in the size of the Atlantic Warm Pool (AWP) on interannual time scales. In large AWP years when the North Atlantic Subtropical High becomes weaker and moves further eastward relative to the small AWP years, a large part of the southeast U.S. including Florida comes under the influence of relatively strong anomalous low-level northerly flow and large-scale subsidence consistent with the theory of the Sverdrup balance. This tends to suppress the diurnal convection over the Florida panhandle coast in large AWP years. This study is also an illustration of the benefit of dynamic downscaling in understanding the low-frequency variations of the sea breeze.

  6. Modeling mesoscale diffusion and transport processes for releases within coastal zones during land/sea breezes

    International Nuclear Information System (INIS)

    This document discusses the impacts of coastal mesoscale regimes (CMRs) upon the transport and diffusion of potential accidental radionuclide releases from a shoreline nuclear power plant. CMRs exhibit significant spatial (horizontal and vertical) and temporal variability. Case studies illustrate land breezes, sea/lake breeze inflows and return flows, thermal internal boundary layers, fumigation, plume trapping, coastal convergence zones, thunderstorms and snow squalls. The direct application of a conventional Gaussian straight-line dose assessment model, initialized only by on-site tower data, can potentially produce highly misleading guidance as to plume impact locations. Since much is known concerning CMRs, there are many potential improvements to modularized dose assessment codes, such as by proper parameterization of TIBLs, forecasting the inland penetration of convergence zones, etc. A three-dimensional primitive equation prognostic model showed excellent agreement with detailed lake breeze field measurements, giving indications that such codes can be used in both diagnostic and prognostic studies. The use of relatively inexpensive supplemental meteorological data especially from remote sensing systems (Doppler sodar, radar, lightning strike tracking) and computerized data bases should save significantly on software development costs. Better quality assurance of emergency response codes could include systems of flags providing personnel with confidence levels as to the applicability of a code being used during any given CMR

    The influence of the method of grinding coke breeze on the strength and the behavior of extrusion briquette (BREX) during static loading is studied. It is found that the size, the shape, and the surface relief of coke breeze particles affect the character of BREX fracture. The application of a shearing extruder for preliminary refinement of coke breeze can result in viscoelastic fracture of BREX due to an increase in its impact toughness.

    Full Text Available High time-resolved aircraft data, concurrent surface measurements and air quality model simulations were explored to diagnose the processes influencing aerosol chemistry under the influence of lake-breeze circulations in a polluted region of southwestern Ontario, Canada. The analysis was based upon horizontal aircraft transects at multiple altitudes across an entire lake-breeze circulation. Air mass boundaries due to lake-breeze fronts were identified in the aircraft meteorological and chemical data, which were consistent with the frontal locations determined from surface analyses. Observations and modelling support the interpretation of a lake-breeze circulation where pollutants were lofted at a lake-breeze front, transported in the synoptic flow, caught in a downdraft over the lake, and then confined by onshore flow. The detailed analysis led to the development of conceptual models that summarize the complex 3-D circulation patterns and their interaction with the synoptic flow. The identified air mass boundaries, the interpretation of the lake-breeze circulation, and best estimates for air parcel circulation times in the lake-breeze circulation (1.2 to 3.0 h enabled formation rates of oxygenated organic aerosol (OOA/ΔCO and SO42− to be determined. The formation rate for OOA, relative to excess CO, was found to be 2.5–6.2 μg m−3 ppmv−1 h−1 and the SO42− formation rate was 1.8–4.6% h−1. The formation rates are enhanced relative to regional background rates implying that lake-breeze circulations are an important dynamic in the formation of SO42− and secondary organic aerosol. The presence of cumulus clouds associated with the lake-breeze fronts suggests that these enhancements could be due to cloud processes. Additionally, the effective confinement of pollutants along the shoreline may have limited pollutant dilution

    1993-01-01

    Data collected during the Convective and Precipitation/Electrification Experiment were analyzed as part of an investigation of the sea breeze in the vicinity of Merritt Island, Florida. Analysis of near-surface divergence fields shows that the classical 24-hour oscillation in divergence over the island due to the direct sea breeze circulation is frequently disrupted and exhibits two distinct modes: the classical sea breeze pattern and deviations from that pattern. A comparison of clear day surface energy fluxes with fluxes on other days indicates that changes in magnitudes were dominated by the presence or absence of clouds. Non-classical sea breeze days tended to lose more available energy in the morning than classical sea breeze days due to earlier development of small cumulus over the island. A composite storm of surface winds, surface energy fluxes, rainfall, and satellite visible data was constructed. A spectral transmittance over the visible wavelengths for the cloud cover resulting from the composite storm was calculated. It is shown that pre-storm transmittances of 0.8 fall to values near 0.1 as the downdraft moves directly over the site. It is also found that under post-composite storm conditions of continuous clear sky days, 3.5 days are required to evaporate back into the atmosphere the latent heat energy lost to the surface by rainfall.

    2016-02-01

    A unique feature observed in the tropical and subtropical coastal area is the diurnal sea-breeze/land-breeze cycle. We examined the nearshore waves at 5 and 15 m water depth during the active sea/land breeze period (January-April) in the year 2015 based on the data measured using the waverider buoys moored in the eastern Arabian sea off Vengurla, central west coast of India. Temporal variability of diurnal wave response is examined. Numerical model Delft3D is used to study the nearshore wave transformation. The wave height increased due to the sea breeze and reached its peak at ˜ 13:00 UTC at 15 m water depth, whereas the peak significant wave height is at 12:00 UTC at 5 m water depth. Due to the influence of the land/sea breeze system, the range of the peak wave period in 1 day varied up to 8 s. Reduction in the wave height of wind-sea is around 20 % and that of the swell is around 10 % from 15 to 5 m water depth.

    Full Text Available The Practicum –understood not only as external practices developed by future teachers in schools, but also as the tutorials, seminars and projects done at the University–, is an essential component of initial teacher training. Given the importance of this topic, this paper includes the results obtained in a trans-sectional quantitative descriptive study focused on learning how sampled students from the Primary Teaching and Preschool Teaching Degree Programs from a public university in Madrid evaluate the organization of Practicums I and II, and the support they received from related personnel from the University and the education institution where the practicums took place. A questionnaire was designed to obtain this information from students from these programs and was answered by 426 students. To validate the questionnaire, the Lawshe’s formula was used, which establishes a Content Validity Index (CVI of 0.62, with ten expert judges for agreement not to be reached by chance. In addition, the information provided by the sample was coded in a database for further processing with SPSS 15.0. Using this software, descriptive analyzes were performed to determine the distribution of the sample in each of the variables defined in this study. Finally, results showed a clear tendency to perceive the training institution (the University and its most representative agent (tutor as insufficient to meet the demands for emotional, professional and pedagogical support. On the contrary, centers where practicum is conducted and collaborating teachers are seen not only as the main sources of orientation and guidance during the Practicum, but also as references in the acquisition and development of professional competences.

  11. Interaction of a cold front with a sea-breeze front Numerical simulations

    Science.gov (United States)

    Rhodin, A.

    1995-08-01

    This paper presents simulations of a front which passed the coast between the North Sea and northern Germany and thereby experienced some modifications of its mesoscale characteristics. The event was observed during the field experiment FRONTEX'89. The two-dimensional non-hydrostatic simulations presented in this paper resemble some of the observed characteristics and yield a detailed description of the evolution of the surface front. Over the sea several narrow frontal rain bands develop in the boundary layer which becomes unstable due to the increasing sea surface temperature near the coast. The rain bands move forward relative to the front due to the cross frontal circulation which is enhanced by the release of latent heat in the ascending warm air and by the cooling of the cold air below by evaporating precipitation. Over the heated land surface a sea-breeze front develops ahead of the synoptic-scale cold front. The strong frontal gradients of the sea-breeze front mask the broader frontal zone of the cold front at the ground. The sea-breeze front triggers deep convection ahead of the cold front in the afternoon and takes over all characteristics of the synoptic-scale front in the evening. The simulations show the mechanisms that caused the observed evolution and modification of the synoptic-scale cold front. They emphasize the strong influence of the surface heat fluxes on the characteristics of fronts on the mesoscale. The most important feature of the numerical model, necessary for the proper representation of the frontal characteristics on the mesoscale, is its high resolution. The simulations are restricted by the difficulties of finding an initial state and appropriate boundary conditions so that the results fit the observations for a long time period and that spin-up problems are avoided.

  12. A numerical study of the interactions of urban breeze circulation with mountain slope winds

    Ganbat, Gantuya; Baik, Jong-Jin; Ryu, Young-Hee

    2015-04-01

    The two-dimensional interactions of urban breeze circulation with mountain slope winds are investigated using the Weather Research and Forecasting (WRF) model coupled with the Seoul National University Urban Canopy Model (SNUUCM). A city is located near an isolated mountain, and there is no basic-state wind. Circulation over the urban area is asymmetric and characterized by the weakened mountain-side urban wind due to the opposing upslope wind and the strengthened plain-side urban wind in the daytime. The transition from upslope wind to downslope wind on the urban-side mountain slope occurs earlier than that on the mountain slope in a simulation that includes only an isolated mountain. A hydraulic jump occurs in the late afternoon, when the strong downslope wind merges with weaker mountain-side urban wind and stagnates until late evening. The sensitivities of the interactions of urban breeze circulation with mountain slope winds and urban heat island intensity to mountain height and urban fraction are also examined. As mountain height decreases and urban fraction increases, the transition from urban-side upslope wind to downslope wind occurs earlier and the urban-side downslope wind persists longer. This change in transition time from urban-side upslope wind to downslope wind affects the interactions between urban breeze circulation and mountain slope winds. Urban heat island intensity is more sensitive to urban fraction than to mountain height. Each urban fraction increase of 0.1 results in an average increase of 0.17 °C (1.27 °C) in the daytime (nighttime) urban heat island intensity. A simulation in which a city is located in a basin shows that the urban-side downslope wind develops earlier, persists longer, and is stronger than in the simulation that includes a city and an isolated mountain.

  13. Sea-Breeze and Topographic Influences on the Planetary Boundary Layer in the Coastal Upwelling Area of Cabo Frio (Brazil)

    Science.gov (United States)

    Ribeiro, F. N. D.; Soares, J.; Oliveira, A. P.

    2016-01-01

    We use a fully coupled oceanic-atmospheric model to investigate the sources and sinks of turbulent kinetic energy in the Cabo Frio coastal area and to determine the role of topography and the sea breeze in planetary boundary-layer (PBL) development. The study area presents similar boundary-layer characteristics than other coastal upwelling areas with complex topography, such as increased stability and low-level jets. The results show that the major effect of upwelling, over the investigated area, is to maintain low temperatures in the lower atmosphere over the coastal zone, sustaining a strong temperature inversion that precludes the vertical PBL development. Therefore, the cooling effect reduces the horizontal thermal contrast between land and water, generating a negative feedback between the intensity of the sea breeze and the intensity of the upwelling. The topography at Cabo Frio prevents this cooling effect from propagating inland, since it limits the penetration of the sea-breeze circulation.

  14. An observational study of the summer Mediterranean Sea breeze front penetration into the complex topography of the Jordan Rift Valley

    Naor, R.; Potchter, O.; Shafir, H.; Alpert, P.

    2015-09-01

    The Mediterranean summer sea breeze front (SBF) climatic features of penetration into the complex topography of the Jordan Rift Valley (JRV) were investigated. It was shown that the SBF penetration into the JRV occurs in a well-defined chronological order from north to south. One exception to this general rule is the breeze penetration of Sdom, which occurs after it has penetrated the Arava which is located further south, probably due to the micro-climatic effect of the Dead Sea. It was also noted that the breeze increases the local specific humidity as it reaches the JRV in spite of significant temperature increases. The temperature reaches its daily peak 2 to 3 h later in the southern valley compared to the northern valley and is suggested to be due to the later SBF penetration and the valley structure. The pre-SBF line features in the JRV are described.

    The research reported in the present paper has the objective to develop improved operational techniques for sea breeze (SB) initiated convective storms. It is pointed out that the sea breeze is a relatively simple mesoscale circulation. The considered studies are mainly concerned with detailed thunderstorm potential forecasts during the next several hours, taking into account real-time predictions using new supercomputer technology. Thunderstorm and coastal mesoscale circulations are discussed along with the P3DM model sea. The considered code represents the result of a further development of the NOAA Florida sea breeze model which was introduced by Pielke (1974). After its modificataion, the model was renamed the Prognostic Three Dimensional Mesoscale (P3DM) Model, with its 2-D connterpart the P2DM. Attention is also given to real time climatology, and a case study concerned with developments occurring on 5 May 1984 over the Florida Peninsula.

    1993-01-01

    Observations of the diurnal evolution of the planetary boundary layer over the Amazon rain forest, made at sites close to the confluence of the Solimoes and Negro rivers (approximately at 3 deg S, 60 deg W) near Manaus, Amazonas, Brazil, show the existence of a diurnal rotation of the wind near the surface and the frequent presence of low-level nocturnal wind maxima. These circulations are shown to be plausibly explained as elements of a river and land breeze circulation induced by the thermal contrast between the rivers and the adjacent forest.

    International Nuclear Information System (INIS)

    The coastal sites present special features so much by the dominant wind system then by the lower layers of the atmosphere. Two types of experiments were handled on a coastal site in presence of sea breeze. First, vertical atmospheric sounding by radiosounding and by throwing experimental balloons; then the discharge of tracer: the SF6. The first experiment lead us to put in a prominent position the Internal Boundary Layer and the determination of its height. Whereas the second experiment allowed us to estimate the diffusion parameters of the site as well as to obtain interesting conclusions on diffusivity of the environment studied and the influence of certain factors

  20. Theoretical calculations of interactions between urban breezes and mountain slope winds in the presence of basic-state wind

    Seo, Jaemyeong Mango; Ganbat, Gantuya; Han, Ji-Young; Baik, Jong-Jin

    2015-11-01

    Many big cities around the world are located near mountains. In city-mountain regions, thermally and topographically forced local winds are produced and they affect the transport of pollutants emitted into the urban atmosphere. A better understanding of the dynamics of thermally and topographically forced local winds is necessary to improve the prediction of local winds and to cope with environmental problems. In this study, we theoretically examine the interactions of urban breezes with mountain slope winds in the presence of basic-state wind within the context of the response of a stably stratified atmosphere to prescribed thermal and mechanical forcing. The interactions between urban breezes and mountain slope winds are viewed through the linear superposition of individual analytical solutions for urban thermal forcing, mountain thermal forcing, and mountain mechanical forcing. A setting is considered in which a city is located downwind of a mountain. In the nighttime, in the mountain-side urban area, surface/near-surface horizontal flows induced by mountain cooling and mountain mechanical forcing cooperatively interact with urban breezes, resulting in strengthened winds. In the daytime, in the urban area, surface/near-surface horizontal flows induced by mountain heating are opposed to urban breezes, giving rise to weakened winds. It is shown that the degree of interactions between urban breezes and mountain slope winds is sensitive to mountain height and basic-state wind speed. Particularly, a change in basic-state wind speed affects not only the strength of thermally and mechanically induced flows (internal gravity waves) but also their vertical wavelength and decaying rate. The examination of a case in a setting in which a city is located upwind of a mountain reveals that basic-state wind direction is an important factor that significantly affects the interactions of urban breezes with mountain slope winds.

  1. The Problematic Nature of the Practicum: A Key Determinant of Pre-service Teachers' Emerging Inquiry-Based Science Practices

    Science.gov (United States)

    Fazio, Xavier; Melville, Wayne; Bartley, Anthony

    2010-10-01

    This article disseminates findings from a multi-year study regarding secondary preservice science teachers’ perceptions toward inquiry-based science teaching, and the extent these perceptions are augmented by their practicum. While findings indicated that preservice teachers did improve their understanding and capability of using scientific inquiry due to their methods course, the role of practicum in supporting their newly developed perceptions was problematic. Issues ranging from associate teacher subjugation, availability of resources, time constraints, and the need to address curriculum standards were the most commonly cited reasons for preservice teachers’ difficulty in creating an inquiry-based environment during their practicum. Implications are presented highlighting the importance of practicum experiences as a key determinant of pre-service science teachers’ emerging inquiry-based science views and practices.

    2004-06-01

    Sea breeze characteristics around Kalpakkam tropical coastal site are studied using an Advanced Regional Prediction System (ARPS) mesoscale model, which is non-hydrostatic, compressible atmospheric prediction model following the terrain coordinate system. Various options such as surface physics, atmospheric radiation physics, Coriolis force, microphysics, cumulus parameterization and 1.5 level TKE closure scheme for diffusion are included in the model. A joint meteorological field experiment was carried out by IITM-Pune and IGCAR at Kalpakkam by deploying state-of-the-art sensors and tether balloon systems for observing the height profiles of meteorological parameters. The data obtained from the field experiment are used here to compare the results from numerical simulations. From the simulated results, it is seen that duration of the sea breeze is 6 hours which agrees well with the observations. The height of the Thermal Internal Boundary Layer (TIBL) is also simulated from the vertical profiles of potential temperature. Simulated wind speed and wind directions are compared with the 50m tower data and potential temperature profiles are compared with the kytoon data. Results are in good agreement with the observed values except during night time wherein a small difference is seen in the wind speed.

    As patient advocates, nurses are responsible for speaking up against unsafe practices. Nursing students must develop the confidence to speak up for patient safety so that they can hold themselves, as well as their peers and coworkers, accountable for patients' well-being. The purpose of this study was to examine the effects of a senior practicum course on confidence for speaking up for patient safety in nursing students. Confidence in speaking up for patient safety was measured with the Health Professional Education in Patient Safety Survey. The study showed a significant increase in nursing students' confidence after the senior practicum course, but there was no significant change in students' confidence in questioning someone of authority.

    There has been an increasing public interest in health care issues such as wellness, self-care, and the importance of taking personal responsibility for one's health. In addition to learning preventive health lifestyle measures, this growing consumer interest involves decisions regarding the purchase and use of health products and health services. There is a significant need for effective consumer health education in the schools that focuses not only on transmission of information, but on the development of decision-making skills and on opportunities for practical application. This paper describes an approach to facilitate the development of a self-care practicum experience in consumer health instruction, making use of the resources and expertise of both the school health educator and the school nurse. The approach describes how a planned practicum can move consumer instruction from an information-receiving experience to a participatory experience that facilitates the development of consumer decision-making skills.

    Physical assessment is an important component of professional nursing practice. New nurse graduates experience difficulty transitioning the traditional head to toe physical assessment into real world nursing practice. This study was conducted to provide current data concerning physical assessment competencies utilized consistently by registered nurses. This quantitative study used a 126 item survey mailed to 900 Registered Nurses. Participants used a Likert-type scale to report frequency of use for physical assessment competencies. Thirty seven competencies were determined to be essential components of the physical assessment, 18 were determined supplemental, and 71 were determined to be non-essential. Transition of the new graduate nurse into professional practice can be enhanced by focusing content in physical assessment practicum courses on the essential competencies of physical assessment. Faculty for the university has analyzed data from this study to support evidence based changes to the undergraduate nursing program physical assessment practicum course. PMID:24083881

    Background: The shortage of skilled personnel is ubiquitous, basic and further training is a key aspect in the recruitment of new medical colleagues. The significance of the nursing practicum in its function as gateway to the gynaecology and obstetrics discipline is practically unexplored. Methods: In an online questionnaire, medical students in all German faculties were questioned about the practica in their courses. The questionnaire reached 9079 medical students. 149 participants in nursing practica were selectively asked to answer 140 questions. We analysed those students who could, on the basis of their experiences in nursing practica, imagine undertaking an internship (clinical elective) in gynaecology (internship yes “Iy”) separately from those who could not or were still undecided (internship no “In” or, respectively, internship perhaps “Ip”). Results: Altogether 149 medical students who participated in a nursing practicum in the gynaecology discipline were selected, of these 94.9 % were female. 92 (61.7 %) of the students replied that, after their gynaecological nursing practicum, they wanted to undertake an internship in gynaecology (Iy); 39 (26.2 %) answered negatively (In) and 18 (12.1 %) were still undecided (Ip). With regard to the parameters gender, age and duration of study, there were no significant differences among the 3 groups (χ2 0.83). Besides the didactic and professional quality of the training, Iy also mentioned having had a higher practical orientation. They attained their aims more frequently, were better integrated in the health-care team and acquired more practical competences. Satisfaction with the practicum was evaluated as highest among the Iy. Discussion: Those students who could imagine taking an internship in gynaecology were seen to be more satisfied with their practica than those participants who declined or were undecided. The high proportion of females is an early indicator for a feminisation of the

    This qualitative multiple-comparative case study investigates (1) The reported experiences and impressions of four pre-service teachers (PTs) on practicum placement in four different classrooms (grades 1-9) where a new Steps to Inquiry (SI) framework was being utilized to support students conducting open inquiry; (2) The relative dispositions of the PTs toward conducting open inquiry, as indicated by their core conceptions regarding science, the purpose of education, effective teaching, and the capacity of students. Findings indicate that (1) although there were differences in the experiences of the four PTs, all four had an opportunity to observe and/or facilitate students conducting open inquiry with the SI framework, and after the practicum, all of them reported that they would like to include open inquiry in their own classrooms in the future; (2) one PT already possessed core conceptions indicative of a favorable disposition toward open inquiry before the placement; another altered her core conceptions substantially toward a favorable disposition during the placement; a third altered her conceptions regarding the capacity of students; and one PT maintained core conceptions indicative of a disposition that was not favorable to open inquiry despite the pronouncements that she would like to conduct open inquiry with students in their own future classroom. Possible reasons for the differences in the responses of the four pre-services teachers to the practicum placement are discussed.

    International Nuclear Information System (INIS)

    Surface measurements of windspeed, direction, and ozone concentration collected at Walloops Island, Virginia, during the summers of 1977 and 1978 are analyzed to study the effects of the dominant mesoscale sea breeze circulation on th local photochemical oxidant levels. A bimodality in the atmospheric dynamics is linked to systematic variations in ozone concentration. It is concluded that during certain phases of the two circulation modes, increased wind speed reduces the resistance of the earth's surface to the deposition of ozone, and decreased ozone concentration levels result. For other phases, light wind occur, signifying high resistance to deposition and high ozone levels. This modulation by the local dynamics is a major impediment for pollutant studies in coastal environments, especially those centering on transport, because it tends to mask other processes that may be occurring

    2011-12-01

    Full Text Available The sea breeze (SB is a thermally induced boundary layer phenomenon that occurs at coastal locations throughout the world. Previous satellite remote sensing studies used low-level clouds formed over the sea-breeze convergence zones to identify the SB. In this study continuous thermal infrared data from a geostationary satellite (Meteosat Second Generation and concurrent field measurements were used to detect and characterize the SB in clear sky conditions during the summer. Surface data (wind speed and direction from 11 sites over Israel for ten summer days in July 2010 for three different synoptic circulation categories were selected.

    In order to assess the impact of the synoptic induced flow on the SB, we looked for the best agreement between surface and satellite SB timing. An independent classification of synoptic categories performed for the ten summer days revealed two distinct patterns of the SB. During weak horizontal pressure gradient (Weak Persian Trough and High to the West, which enables full development of the SB, the timing of the SB from satellite and field measurements were well correlated (R2=0.75, as compared to unfavorable atmospheric conditions (Deep Persian Trough yielding lower value (R2=0.5. The SB was identified by surface measurements in an earlier time of the day, with respect to the satellite column integrated measurements.

    Visualizing a product of time series analysis of the satellite data enabled clear distinction of SB behavior under different synoptic categories. Over desert regions the strong thermal contrast enables detection of the SB even under suppressing synoptic conditions (Deep Persian Trough.

    This method enables detection and timing of the SB over desert regions where clouds and field measurements are scarce, and is applicable worldwide.

  2. A sea breeze tracer study with the MATHEW/ADPIC transport and diffusion model

    International Nuclear Information System (INIS)

    The three-dimensional MATHEW/ADPIC (M/A) model was developed for the assessment of the consequences of a release of radioactive materials into the atmosphere. The M/A model has been applied to several continuous tracer releases under sea breeze conditions at Montalto on the Tyrrhenian coast approximately 100 km northwest of Rome, at the construction site of a nuclear power plant. The MATHEW model generates a mass conservative three-dimensional gridded wind field including terrain from available interpolated meteorological data. ADPIC is a three-dimensional numerical particle-in-cell transport and diffusion model capable of simulating the time- and space-varying dispersal of atmospheric pollutants under complex conditions. It is a particle-in-cell model in which Lagrangian 'mass' particles are transported inside a fixed Eulerian grid. The M/A evaluation of the sea breeze data is shown in terms of the fraction of computed samples agreeing with measured values within a factor N, versus an angle deltatheta which is a precision parameter inversely proportional to the model's accuracy. Indications are that a small average angular shift of deltatheta=10 deg. in the direction of the computed tracer plume will provide very good agreement with observed concentrations. It is found that for these experiments the vertical and horizontal model diffusion parameters need to be decoupled because of different turbulence characteristics in the vertical and horizontal planes. The sensitivity of the M/A model results to meteorological parameters and diffusion coefficients is examined, with the most important variable being wind direction. (author)

    Practical experience is central to the education and training of neuropsychologists, beginning in graduate school and extending through postdoctoral fellowship. However, historically, little attention has been given to the structure and requirements of practicum training in clinical neuropsychology. A working group of senior-level neuropsychologists, as well as a current postdoctoral fellow, all from a diverse range of settings (The AACN Practicum Guidelines Workgroup), was formed to propose guidelines for practicum training in clinical neuropsychology. The Workgroup reviewed relevant literature and sought input from professional organizations involved in education and training in neuropsychology. The proposed guidelines provide a definition of practicum training in clinical neuropsychology, detail entry and exit criteria across competencies relevant to practicum training in clinical neuropsychology, and discuss the relationship between doctoral training programs and practicum training sites. The proposed guidelines also provide a methodology for competency-based evaluation of clinical neuropsychology practicum trainees and outline characteristics and features that are integral to an effective training environment. Although the guidelines discussed below may not be implemented in their entirety across all clinical neuropsychology practicum training sites, they are consistent with the latest developments in competency-based education.

    The state of the atmosphere near the coast is affected by the interaction of atmosphere and ocean. Thus, in order to predict the state of the atmosphere in coastal areas correctly, different oceanic characteristics and processes need to be considered. The goal of the present study is to identify whether tidal effects are relevant for the prediction of sea breezes at the German North Sea coast. For that an atmosphere model was extended to simulate the ocean in different complexities, leading to a coupled ocean-atmosphere-model. In contrast to many other studies the present study considers a two-way-coupling for momentum. That is, the simulation not only consideres a transfer of momentum from the atmosphere to the ocean but also a transfer from the ocean to the atmosphere. The model system is tested for a sea breeze situation, which is a common phenomenon in the German Bight in May and June. Six different scenarios with a grid size of 1.5 km are calculated: Inundated/dry mudflats for the entire simulation, high/low tide at Heligoland at midday and high/low tide at Heligoland at midday with a two-way-coupling for momentum. Tides influence sea breezes in two ways. Firstly, they influence the heat budget in coastal areas, as mudflats are inundated and fall dry. The study reveals that the air temperature in 10 m height follows the tidal cycle and thus reflects an inundated scenario during high tide and a dry scenario during low tide, respectively. Because of the alternation of the air temperature above the mudflats, the temperature gradient between land and sea areas is influenced, which modifies the sea breeze development. A time difference of one hour is found for the formation of the sea breeze front and its related cloud formation between those scenarios where low tide and high tide occur at midday respectively. Also the inland penetration of sea breezes is influenced by tides: with incoming tide their fronts are moved further inland. Secondly, tidal currents

    Sea and land breezes are common meteorological phenomena in most coastal regions of the world. The thermally induced mesoscale circulation of sea breezes modifies the planetary boundary layer (PBL) by forming a convective internal boundary layer (CIBL), which can trap dust and other pollutants in the thin convective layer while the return flow can transport dust and pollutants from the land towards the sea. We used the Advanced Research WRF (ARW) modeling system to study the structure and dynamics of sea breezes in the middle region of the Red Sea (around 25°N) on the western coast of Saudi Arabia. Results showed the existence of two thermal circulations on both the western and eastern coasts of the Red Sea. The modeling results are consistent with observations from buoys and meteorological towers along the Saudi Arabian coast and suggest that the onset of the sea breeze in this area typically occurs at about 0800 Local Standard Time (LST). The sea breeze decays after 1700 LST, although the timing of the onset and decay could be affected by the sea-land thermal gradient, topography, the sea-land orientation and the direction and strength of the wind. The depth of the predicted inflow layer reaches one kilometer while the height of sea breeze head may reach three kilometers. The rocky mountain range of Al-Sarawat, along the Saudi coast line, restricts the inland propagation of the sea breeze and significantly affects the structure of the flow. We conducted a detailed process analysis of our simulation results to understand the sea breeze and PBL interaction and its effect on local meteorology and dust transport.

    A Prognostic Three-Dimensional Model (P3DM) to produce 1- to 12-hr predictions of sea breeze convective (SBC) storms at KSC is described. The P3DM was developed to account for a scale of about 10 km, interactions between surface heat and moisture fluxes, boundary layer convergence, the movement of moisture into cloud formation zones, and alterations in the convective potential in the lower levels of the atmosphere during the diurnal cycle. Initialized with wind, temperature, specific humidity and local water temperature data, the model allows for the distortion of the boundary layer moisture and thermal fields by sea breeze conditions. The results of three simulations of events leading to the onset of SBC storms are presented to demonstrate the model's capabilities, and techniques which may enhance the accuracy of the predictions are discussed.

    1994-01-01

    Over the southern California coastal region, observations of the vertical distributions of pollutants show that maximum concentrations can occur within temperature inversion layers well above the surface. A mesoscale model is used to study the dynamical phenomena that cause such layers, including sea breezes and mountain flows, and to study the characteristics of air pollutant transport in a coastal environment capped by a temperature inversion. The mathematical and physical structure of the model is described. Two-dimensional simulations corresponding to four configurations of coastal plains and mountains are discussed. The simulations reveal that pollutant transport over a coastal plain is strongly influenced by the topographic configuration, including the height of coastal mountains and their distance from the coastline. Sea breezes induced by land-sea thermal contrasts, as well as upslope winds induced along mountain flanks, both create vertical transport that can lead to the formation of elevated pollution layers. The sea-breeze circulation generates pollution layers by undercutting the mixed layer and lofting pollutants into the stable layer. Heating of mountain slopes acts to vent pollutants above the mountain ridge during the day; during the evening, pollutants can be injected directly into the inversion layer from the decaying upslope flows. In a land-sea configuration with mountains close to the coastline, the sea breeze and heated-mountain flow are strongly coupled. In the afternoon, this interaction can produce upslope flow from which polluted air is detrained into the inversion layer as a return circulation. When the mountains lie farther inland, however, pollutants may be trapped aloft when the mixed layer stabilizes in the late afternoon. As the nocturnal boundary layer forms over the coast in the evening, polluted mixed-layer air is effectively left behind in the inversion layer. In the Los Angeles Basin, the formation mechanism for elevated

In the southern North Sea, renewable energy production targets, set by European governments to counter growing concerns over climate change, have sparked an initiative to rapidly construct a large number of offshore wind farms. To meet the targets, the industry must overcome many challenges, one of which is to capitalize on the coastal and offshore wind resource. One particular relative component of the sea breeze system, including the...

    Tourism plays a crucial role for the development of coastal areas. Despite the mildness of Madeira's climate, very hot days can occur during summer, a situation to which most tourists from northern Europe (the majority of foreign tourists) are poorly adapted. As sea breezes strongly contribute to moderate heat stress in urban environments, their influence on the thermal comfort on the island has been studied. Sea breezes occurred on 84 % of the days during the period under study (May to October 2006). They usually start around 09:30 h and end after 22:00 h, with an average duration of about 12:50 hours and a mean velocity of 2.9 m/s. Physiologically Equivalent Temperature (PET) was used to evaluate the thermal comfort of a sample of days during the summer of 2006. It was concluded that most of the sites in the city are ''slightly comfortable'' during normal days with sea breeze, but only shore sites and the highest green areas offer some comfort during hot days. Inside the city, the thermal perception is generally ''hot'' and strong heat stress can occur. As sea breezes are important to mitigate heat stress, some basic guidelines were presented: urban planners should take advantage of this wind system avoiding dense construction near the shoreline that would act as a barrier to the renewal of the air inside the city. In terms of tourism, planners and local authorities should provide solutions to mitigate the negative effects during hot periods, creating a system to warn and relocate more vulnerable tourists to places near the shore line, to the mountains, to gardens and air-conditioned buildings. In combination with other components (beauty of the island, gastronomy, cultural values and safety), climate information can be a factor of attractiveness to tourists. (orig.)

    With the velocity vector and temperature of the pristine interstellar neutral (ISN) He recently obtained with high precision from a coordinated analysis summarized by McComas et al.2015b, we analyzed the IBEX observations of neutral He left out from this analysis. These observations were collected during the ISN observation seasons 2010---2014 and cover the region in the Earth's orbit where the Warm Breeze persists. We used the same simulation model and a very similar parameter fitting method to that used for the analysis of ISN He. We approximated the parent population of the Warm Breeze in front of the heliosphere with a homogeneous Maxwell-Boltzmann distribution function and found a temperature of $\\sim 9\\,500$ K, an inflow speed of 11.3 km s$^{-1}$, and an inflow longitude and latitude in the J2000 ecliptic coordinates $251.6^\\circ$, $12.0^\\circ$. The abundance of the Warm Breeze relative to the interstellar neutral He is 5.7\\% and the Mach number is 1.97. The newly found inflow direction of the Warm Bree...

  14. Numerical analysis of air pollution in a combined field of land/sea breeze and mountain/valley wind

    International Nuclear Information System (INIS)

    Air pollution in the presence of two types of local flows (i.e., land/sea breeze and mountain/valley wind) was studies by advection simulation of the cluster of hypothetical fluid particles, and transport/chemistry calculation employing a three-dimensional Eulerian model for 20 advected species and about 90 chemical reactions. Three-dimensional flow fields over the River Yahagi basin in Japan were estimated for 48 h using an objective method with routine wind observations. Those obtained showed characteristics of the combined local flows such that in the daytime sea breeze and valley wind tend to form one united flow with substantial wind velocity in the whole region and, in contrast, land breeze and mountain wind during the nighttime form two separated circulating flows with a clear weak-wind area between the two local flow regimes. The results of the advection simulation of fluid particles and the transport/chemistry calculation using those flows as inputs elucidated how the features found in the diurnally varying, complex local flows contribute to produce characteristic time-variations of the concentrations of both primary and secondary pollutants. Among others, dynamics of NO2, HNO3, PAN, O3, SO2, and SO4/sup =/ concentrations are discussed

  15. Atmospheric electrical field measurements near a fresh water reservoir and the formation of the lake breeze

    Directory of Open Access Journals (Sweden)

    2016-06-01

    Full Text Available In order to access the effect of the lakes in the atmospheric electrical field, measurements have been carried out near a large man-made lake in southern Portugal, the Alqueva reservoir, during the ALqueva hydro-meteorological EXperiment 2014. The purpose of these conjoint experiments was to study the impact of the Alqueva reservoir on the atmosphere, in particular on the local atmospheric electric environment by comparing measurements taken in the proximity of the lake. Two stations 10 km apart were used, as they were located up- and down-wind of the lake (Amieira and Parque Solar, respectively, in reference to the dominant northwestern wind direction. The up-wind station shows lower atmospheric electric potential gradient (PG values than the ones observed in the down-wind station between 12 and 20 UTC. The difference in the atmospheric electric PG between the up-wind and the down-wind station is ~30 V/m during the day. This differential occurs mainly during the development of a lake breeze, between 10 and 18 UTC, as a consequence of the surface temperature gradient between the surrounding land and the lake water. In the analysis presented, a correlation is found between the atmospheric electric PG differences and both wind speed and temperature gradients over the lake, thus supporting the influence of the lake breeze over the observed PG variation in the two stations. Two hypotheses are provided to explain this observation: (1 The air that flows from the lake into the land station is likely to increase the local electric conductivity through the removal of ground dust and the transport of cleaner air from higher altitudes with significant light ion concentrations. With such an increase in conductivity, it is expected to see a reduction of the atmospheric electric PG; (2 the resulting air flow over the land station carries negative ions formed by wave splashing in the lake's water surface, as a result of the so-called balloelectric effect

  19. Evaluation of the atmospheric model WRF on the Qatar peninsula for a converging sea-breeze event

    Qatar, a narrow peninsula covering an area of 11437 sq km, extends northwards into the Arabian Gulf for about 160km and has a maximum width of 88km. The convex shape of the coast-line and narrowness of the peninsula results in the Qatar region experiencing complex wind patterns. The geometry is favorable for formation of the land-sea breeze from both coastal sides of the peninsula. This can lead to the development of sea breeze convergence zones in the middle of the country. Although circulations arising from diurnal thermal contrast of land and water are amongst most intensively studied meteorological phenomena, there is no reported study for the Qatar peninsula and very few studies are reported for the Arabian Gulf region as whole. It is necessary to characterize the wind field for applications such as assessing air pollution, renewable energy etc. A non-hydrostatic mesoscale model, Weather Research and Forecast (WRF) with a nested high resolution grid permits the investigation of such fine scale phenomena. Data from eighteen land based Automated Weather Stations (AWS) and two offshore buoys deployed and maintained by the Qatar Meteorological Department were analyzed. Based on the analysis a clear case of sea breeze convergence were seen on 18 September 2015. Model simulations were used to investigate the synoptic conditions associated with the formation of this event. The season is characterized by week ambient north westerly wind over the Arabian Gulf. The WRF model performance is validated using observed in-situ data. Model simulations show that vertical extent of sea breeze cell was up to 1 km and the converging sea breeze regions were characterized with high vertical velocities. The WRF simulation also revealed that with high resolution, the model is capable of reproducing the fine scale patterns accurately. The error of predictions in the inner domain (highest resolution) are found to be relatively lower than coarse resolution domain. The maximum wind speed

    An atypical occlusion process that occurred in North China on 14 July 2011 is studied based on both observations and a real-data Weather Research and Forecasting (WRF) model simulation. The results show that this atypical occlusion process was significantly different from the traditional, synoptic-scale occlusion process that occurs within extratropical cyclones. It was caused by the merger of two cold-type mesoscale fronts. One of the fronts developed from the gust front of convective storms, while the other was a sea-breeze front. As the two fronts moved towards each other, the warm air between them was squeezed and separated from the surface. An atypical occluded front was formed when the two fronts merged, with the warm air forced aloft. This kind of occlusion is termed a "merger" process, different from the well-known "catch-up" and "wrap-up" processes. Moreover, local convection was found to be enhanced during the merger process, with severe convective weather produced in the merger area.

  1. Fire Whirl Evolution Observed during a Valley Wind-Sea Breeze Reversal

    Directory of Open Access Journals (Sweden)

    Daisuke Seto

    2011-01-01

    Full Text Available This observational study documented the atmospheric environment of a prescribed fire conducted in a narrow valley when a small fire whirl developed during a mesoscale wind reversal. Based on analysis of in situ meteorological measurements, it is hypothesized that the fire whirl formed due to the presence of strong vertical wind shear caused by the interaction of a sea breeze front with a weaker up-valley wind. Vorticity generated by the interaction of the wind shear and the fire front was estimated to be ~0.2 s−1. Peak turbulence kinetic energy was caused by the wind shear rather than the buoyancy generated by the fire front. It was also found that the convective Froude number itself may not be sufficient for fire whirl prediction since it is less relevant to the near-surface boundary-layer turbulence generated by environmental wind shear. Observations from this case study indicate that even low-intensity prescribed fires can result in the formation of fire whirls due to mesoscale changes in the ambient atmospheric environment.

  2. Effect of the catalyzing combustion of coke breeze on the energy saving in sinter process

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    The mechanism of additive ZC-1 for catalyzing combustion of coke breeze in sintering of iron one fines was studied by using X-ray Diffraction, TGA and GC (Gas Chromatographer), by which energy saving was achieved on sinter pot test. The results show that the distance between cleavage planes is enlarged and the π-electrons are re-distibuted because of the insertion of cations/molecules of ZC-1 into the cleavage planes of carbon , resulting in the weakening of C-C bond, improving the adsorption of oxygen and lowering the activation energy of gasification of carbon from 25.8 kJ/mol to 18.9 kJ/mol , and the burning rate being increased and combustion residual reduced, all of which can lead to lower solid fuel consumption . Compared with the sintering test without addition of additives , the solid fuel consumption is reduced by 16.0%, meanwhile, the rate of finished sinter, the output of finished sinter and the tumbling index are increased by 2.03%, 7.0% and 3.71%, respectively, with incorporating 0.2% of additive ZC-1 in the sintering mixture, which is in agreement with the catalyzing mechanism of ZC-1.

  3. Local scale atmospheric diffusion at a coastal site in the presence of breeze effect

    International Nuclear Information System (INIS)

    The aim of this work is the characterization, from the thermal and anemological point of view, of the lower layers of the atmosphere at a coastal site, affected by breeze circulation, in order to set up possible diffusion models for accidental releases of airborne materials, both of short and prolonged duration. Five inland meteorological campaigns, starting from April '82 (Apr., Jul., Oct. 1982, Jan. 1983), have been carried out. An appropriate extension of the research allowed the execution of two more campaigns in the open sea (Apr., Jul. 1983), utilizing the oceanographic ship ''Bannock'' supplied by CNR. The analysis of the data showed the development of a well defined IBL during on-shore flow only in Spring and Summer, while an inversion layer was detectable aloft independently of the season (provided that an anticyclonic situation was present). According to those relevant features a simple diffusion model has been developed for short duration releases at local scale. Finally, the analysis and elaboration of the data collected on site by a meteorological automatic station, allowed the extension of the model to prolonged releases. (author)

  4. Effect of the sea-breeze on the atmospheric stability at the sea-board

    International Nuclear Information System (INIS)

    For the study on the effect of sea breeze on the atmospheric stability in sea-board, a meteorological observation tower of 10 m height was built on the hill which is 30 m high above the sea level, located westward 400 m away from the coast. The tower was provided with anemometers at the top and 6 thermometers at 1.5-70 m above the ground. A phrhelis-radiometer and an anemometer were put around the ground 700 m away from there. By using the data from those instruments, attempt was made to analyze the relationship between wind near the coastline and several stability categories. Pasquille's atomospheric stability category is not always same as the other category for the state of atmospheric stability. The fluctuation of wind direction and the stability categorization by Richardson numbers agreed with Pasquille's stability to some extent in neutral range, but the disagreement developed conspicuously in stable and unstable sides. The three kinds of the stability categolization agree often each other. The relationship between the fluctuation of wind direction and Richardson numbers shows similar tendency. As a means to estimate the stability, particularly to estimate the fluctuation in wind direction, the Pasquille's stability categorization seems to be appropriate for practical use, since the neutral and stable cases arise in high frequency.

  5. A theoretical investigation of large natural barrier effects on SEA breeze and contamination patterns

    International Nuclear Information System (INIS)

    The degree of contamination of a large population center lying in the proximity of a mountain, is expected to be strongly dependent on the mountain presence due to its significant distortion of the flow fields and diffusion processes. The phenomena become even more complex in the presence of sea breeze occurring in the area during daytime. In accident consequence assessment there is a need to develop suitable analytical tools to be able to predict efficiently and correctly such complex situations. The present work refers to a 1000 m two dimensional mountain range surrounded by sea. The orography under consideration represents an idealized west-east cross section of the Athens basin. The diurnal cycle of the mesoscale circulation developing across the mountainous coastline, as well as the effect on the contamination patterns are studied. The major phenomena occurring are discussed. The exercise is also part of the effort to develop the necessary capability in the ADREA-I code under development in NRCPS ''Demokritos'' to treat domain of any complexity and any atmospheric stability in atmospheric dispersion analysis and accident consequence assessment in general

  6. Impacts of boundary layer turbulence and land surface process parameterizations on simulated sea breeze characteristics

    Directory of Open Access Journals (Sweden)

    J.-F. Miao

    2009-06-01

    Full Text Available This paper investigates the sensitivity of sea breeze (SB simulations to combinations of boundary-layer turbulence and land-surface process parameterizations implemented in the MM5 mesoscale meteorological mode for an observed SB case over the Swedish west coast. Various combinations from four different planetary boundary layer (PBL schemes [Blackadar, Gayno-Seaman (GS, Eta, MRF], and two land surface model (LSM schemes (SLAB, Noah with different complexity are designed to simulate a typical SB case over the Swedish west coast. The simulations are conducted using two-way interactively nested grids. Simulated 10-m winds are compared against observed near-surface wind data from the GÖTE2001 campaign to examine the diurnal cycle of wind direction and speed for SB timing. The SB (vertical circulation is also compared in the different experiments. The results show that the different combinations of PBL and LSM parameterization schemes result in different SB timing and vertical circulation characteristics. All experiments predict a delayed SB. The vertical component of the SB circulation varies in the experiments, among which the GS PBL scheme produces the strongest SB circulation. Evident differences between the SLAB and Noah LSMs are also found, especially in maximum of updraft and downdraft velocities of the SB vertical circulation. The results have significant implications for convective initiation, air quality studies and other environmental problems in coastal areas.

  7. A Comparison of Cumulus Parameterizations in Idealized Sea-Breeze Simulations

    Cohen, Charles; Arnold, James E. (Technical Monitor)

    2001-01-01

    Four cumulus parameterizations in the Penn State-NCAR model MM5 are compared in idealized sea-breeze simulations, with the aim of discovering why they work as they do. The most realistic results appear to be those using the Kain-Fritsch scheme. Rainfall is significantly delayed with the Betts-Miller-Janjic scheme, due to the method of computing the reference sounding. This method can be corrected, but downdrafts should be added in a physically realistic manner. Even without downdrafts, a corrected version of the BMJ scheme produces nearly the same timing and location of deep convection as the KF scheme, despite the very different physics. In order to simulate the correct timing of the rainfall, a minimum amount of mass is required in the layer that is the source of a parameterized updraft. The Grell parameterization, in the present simulation, always derives the updraft from the top of the mixed layer, where vertical advection predominates over horizontal advection in increasing the moist static energy. This makes the application of the quasi-equilibrium closure more correct than it would be if the updrafts were always derived from the most unstable layer, but it evades the question of whether or not horizontal advection generates instability. Using different physics, the parameterizations produce significantly different cloud-top heights.

  8. Regional wind-field study in complex terrain during summer sea-breeze conditions

    International Nuclear Information System (INIS)

    A regional-scale data base, consisting of wind and temperature data for June and July of 1977, was developed for the greater San Francisco Bay Area and eastward to the Central Valley. Continuous meteorological measurements were made in the area of a windy pass (Patterson Pass) 3 km east of Lawrence Livermore Laboratory. This area was chosen because of its complex terrain and importance as a downwind topographic feature affecting the dispersal of possible accidental atmospheric releases from the Laboratory and as an area of high wind-energy potential. The results of this study provided the following: (1) a data base, including over 50 stations for use in numerical wind-field regional-scale-model validation; (2) characterization of summer sea breese oscillations of approx. 6 and 12 days (this analysis is useful in calculating wind-power persistence and in understanding summer sea-breeze mechanisms in the Bay Area); and (3) successful application of an optical space-averaging wind sensor over a 1-km path across a pass to provide long-path averaged data more suitable for regional, numerical wind-field models with kilometre-size grid elements

  9. Phenolic resin binder for the production of metallurgical quality briquettes from coke breeze: Part I

    2008-01-15

    Phenol based novalac, resol and the blend of both resins were used as binders in briquette production from coke breeze. The effects of the amount of catalyst on the tensile strength of the cured briquette were studied. The results obtained have indicated that the highest tensile strength could not be attained unless the blend of novalac and resol was used as binder. The most suitable blend was the binder prepared from the hydrochloric acid catalyzed novalac of F/P = 0.5 and the N/P = 0.3 catalyzed resol of F/P = 2.0. When this blend was used as a binder the tensile strength of the cured briquettes did not drop even if they were carbonized at 470 C and 570 C. Their strengths at these carbonization temperatures were 67 MPa and 72 MPa respectively, and the rise in the temperature resulted in some increase in their strength. These results show the fact that as the formed coke briquettes descends from the top of the blast furnace, the rise in temperature will not deteriorate their strength; it will probably improve their properties. Therefore, only curing at 200 C for 2 h will be sufficient for the briquettes to be used as substitute for metallurgical coke in the blast furnace. (author)

    Full Text Available Classroom management is commonly believed to be the key to the success of an instruction. Many student teachers, however, might find it very challenging to handle their classrooms. It is, therefore, necessary to advance their professional practice in the context of a real classroom such as through teaching practicum and reflective practice. This study is aimed at identifying classroom management problems of student-teachers as revealed in their reflective journal entries and to demonstrate how such journal can help them develop their classroom management skills. The participants were 10 student-teachers of the English Department, Satya Wacana Christian University, Salatiga, Central Java, who underwent their teaching practicum at SMP 2 Salatiga. Through the participants’ journals, it was found that the problems lie in managing critical moments, activity, techniques, grouping and seating, authority, tools, and working with people. Further in this study, both pre- and in-service tertiary teachers, curriculum designers, and policy makers will be taken to deeply examine how reflective practice can help cultivate the pre-service’s classroom management skills and to consider the implication for pedagogical practices and innovations in curriculum development.

    Discussions continue within the midwifery profession around the number of and type of clinical experiences required to ensure competent midwifery graduates. Introduction of the three year Bachelor of Midwifery in Australia, almost two decades ago, was intended to reduce the pressure students were under to complete their academic requirements whilst ensuring students developed midwifery practice that encapsulates the philosophical values of midwifery. Currently, midwifery students are mandated to achieve a minimum number of clinical skills and Continuity of Care Experience (CCE) relationships in order to register upon completion of their degree. To achieve these experiences, universities require students to complete a number of clinical practicum hours. Furthermore students are required to demonstrate competent clinical performance of a number of clinical skills. However, there is no evidence to date that a set number of experiences or hours ensures professional competence in the clinical environment. The aim of this paper is to promote discussion regarding the mandated requirements for allocated clinical practicum hours, specified numbers of clinical-based skills and CCE relationships in the context of learning to be a midwife in Australia.

    The understanding of the atmospheric dynamics under sea breeze is crucial for predicting pollution transport and dispersion in coastal areas. We present here a study of the boundary-layer dynamics and the redistribution of the industrial SO2 emissions in the Dunkerque region (51 N, 2.20 E), in the north of France, at the eastern limit of the English Channel. The French Flanders coastal area is strongly industrialized with many refineries and metallurgic factories. This region is a flat area with small hills (up to 200 meters high) located 30 km away from the coast where sea breezes develop frequently all along the year. Thus, the pollutants transport and pollution episodes are mainly governed by the sea-breeze phenomenon under sunny days. By using optical and acoustic remote-sensing instruments (lidar and sodar), the vertical structure of the atmospheric boundary layer has been observed during a whole sea-breeze event in September 2003. The structure and dynamics of the atmosphere and the pollutants transport within has been simulated with a 3D non hydrostatic model Meso-NHC, developed by the C.R.N.M. and Laboratoire d Aerologie, and was compared with the remote-sensing observations. We present the results of our numerical simulations as well as the data of the remote sensing instruments and stations of the air quality network. The thermal internal boundary layer, the gravity current, the atmospheric boundary layer, the nocturnal boundary layer and the residual layer, were observed by the remote sensing instruments and computed by the model. High values of SO2 concentration were observed at the sea-breeze front passage, and the pollutants emitted were uplifted by updrafts in the front. The acceleration of the sea-breeze flow seems to be responsible of the vertical redistribution of the pollutants emitted inside the sea-breeze system by means of vertical ascents in the sea-breeze front. High values of SO2 concentrations computed in the model were accumulating at the

    Full Text Available O objetivo deste trabalho foi testar uma teoria termodinâmica em brisas marítimas-terrestres acopladas com brisas de vale-montanha através de simulações numéricas tridimensionais em uma região da costa leste do Nordeste Brasileiro, considerando a presença e a ausência da topografia. Embora o contraste de temperatura entre as superfícies seja importante na formação da brisa, a eficiência termodinâmica é fundamental na determinação da sua intensidade. Tem-se que a inclinação faz com que a diferença de pressão entre dois pontos fique maior durante o dia e menor durante a noite contribuindo para a formação de brisas marítimas mais intensas e de brisas terrestres menos intensas, respectivamente. A máxima queda de pressão ocorre por volta de três horas antes da máxima intensidade da brisa. Isso porque grande parte da energia disponibilizada para as circulações é gasta para vencer dissipação, principalmente, no período diurno, quando esses processos são realmente efetivos. Do ponto de vista puramente termodinâmico a inclinação da montanha atua para intensificar a brisa durante o dia e para enfraquecê-la durante a noite.In this work we test a thermodynamic theory for sea-land breeze coupled with valley-mountain breeze through tri-dimensional numeric simulations. We verify the presence of such a breeze in Northeast Brazil's east coast and perform experiments with and without the topography of the region. Although the temperature contrast between two surfaces is important in forming the breezes, the thermodynamic efficiency is a key parameter for the breeze intensity. The presence of the slope causes the pressure difference between two points to increase during the day and to decrease during the night. This contributes for more intense daytime breeze and less intense nighttime ones. The maximum pressure drop occurs about three hours prior the maximum intensity of the sea breeze. This is because most of the available

    In this paper, the process of oasis-desert circulation (ODC) is simulated by MM5V3.5 model through designing an ideal oasis-desert scheme and assuming that initial atmosphere is at rest (V = 0). The findings showed that the key of forming special oasis boundary structure is the difference of energy and water between oasis and desert. The evaporation of oasis surface consumes heat energy, and the low temperature of oasis causes an oasis breeze circulation (OBC), which drives an ODC with a downdraft over the oasis and an updraft over the desert. Later, the cold, dry and stable boundary over oasis is gradually formed, on the contrary,the atmospheric boundary over desert on the edge of oasis is hot, humid and unstable and its height is about 600 hPa. The updraft over the desert forms a wet ring that acts as a vertical wall weakening the low-level moisture exchange between the oasis and desert. The downdraft of OBC increases the atmospheric stability that reduces the oasis evaporation. The low-level outflow from the oasis (into the desert) prevents the dry, hot air flowing from the desert into the oasis.Thus an oasis self-preservation mechanism may be formed due to OBC. The horizontal area influenced by oasis is twice as oasis area and the vertical range is four times as oasis. The ODC is strong in the daytime and reaches the strongest at 17:00, and the influenced area is the largest at 20:00.

    The Mediterranean Campaign of Photochemical Tracers-Transport and Chemical Evolution that took place in the greater Athens area from 20 August to 20 September 1994 has confirmed the role of sea-breeze circulation in photochemical smog episodes that had been suggested already by a number of experiments and numerical studies.The meteorological and photochemical modeling of this campaign were discussed in Part I. Part II focuses on the study of the 14 September photochemical smog event associated with a sea-breeze circulation. The objective of the study is to identify and to understand better the nonlinear processes that produce high ozone concentrations. In particular, the effect of land and sea breezes is investigated by isolating the effect of nighttime and daytime emissions on ozone concentrations. The same principle then is used to isolate the effect on ozone concentrations of the two main sources of emissions in the greater Athens area: the industrial area around Elefsis and the Athens urban area. Last, the buildup of ozone from one day to another is investigated.From this study, it comes out that ozone production in the Athens area is mainly a 1-day phenomenon. The increased values of photochemical pollutant (up to 130 ppb at ground level) reached during summertime late afternoons on mountain slopes to the north and northeast of the city are related mainly to the current-day emissions. Nevertheless, the recirculation of old pollutants can have an important effect on ozone concentrations in downtown Athens, the southern part of the peninsula, and over the sea, especially near Aigina Island.

    The operational efficiency of using guidance from a mesoscale numerical model to improve sea breeze thunderstorm forecasts at and around the Shuttle landing strip was assessed. The Prognostic Three-Dimensional Mesoscale (P3DM) model, developed as a sea breeze model, reveals a strong correlation between regions of mesoscale convergence and the triggering of sea breeze convection thunderstorms. The P3DM was modified to generate stability parameters familiar to the operational forecaster. In addition to the mesoscale fields of wind, vertical motion, moisture, temperature, a stability indicator, a combination of model-predicted K and Lifted Indices and the maximum grid cell vertical motion, were proposed and tested. Results of blind tests indicate that a forecaster, provided with guidance derived from model output, could improve local thunderstorm forecasts.

    2014-07-01

    Full Text Available In this paper, the technique of laboratory work on experimental verification of Steiner’s Theorem in laboratory conditions is developed. To do this, specially designed experimental device was used. The main part of such device is a simple physical pendulum, swinging freely about the axis of suspension, consisting of a cylindrical disc set on a thin rod. To determine the moment of inertia of cylindrical body about the axis of vibrations, property of a physical quantity additivity was used. When processing experimental results, functional approximation by a least squares method was applied; as a result, the empirical expression of Steiner’s Theorem was achieved. Results of experimental studies were very close to the results of theoretical calculations. Laboratory work can be easily repeated for a body of arbitrary shape. The methodology used can be recommended for physical practicum in universities as an effective and easy way of experimental verification of Steiner’s theorem.

    Mathematics teacher education programs are designed with an intention, explicit or implicit, to produce graduates who are competent in both pedagogic knowledge and discipline knowledge. This paper explores students' experiences in coming to learn mathematics and mathematics education. Using an example from a quiz question, supplemented with follow-up interviews with students, the paper raises questions as to the effectiveness of programs that adopt traditional approaches to the teaching of mathematics. It is shown how a functionalist perspective was adopted by many of the preservice teachers, which engendered a reproductive approach to teaching. The data raised concerns about preservice teachers' knowledge of volume, their pedagogic knowledge, and the role of the practicum on their learning.

    Full Text Available This article presents a Canadian perspective on the issue of failure to fail in Bachelor of Education programs. The issue of failure to fail in Bachelor of Education programs is one that had not been explored in any great detail. What literature does exist focuses on the strain that a teacher experiences when s/he mentors a student teacher (Siebert, Clark, Kilbridge, & Peterson, 2006 and the wide variety of situations that can result in failure (Sudzina & Knowles, 1992. This study examines whether the issue of failure to fail in final pre-service practica exist and, if so, why? Twelve interviews were conducted at a mid-sized Canadian university in Ontario with university supervisors and associate teachers on the topic of teacher candidate failure during the final teaching practicum. All participants had experience with teacher candidates struggling during practicum. Faculty commented on their supervision of student teachers in Ontario, other provinces in Canada, and the United States. Results indicate that both university supervisors and associate teachers find the decision to fail a student teacher difficult, taking an emotional toll on both the supervisor and the student. University faculty report the decision to fail results in additional work for the faculty responsible; however, failure to fail an underperforming student teacher could diminish the reputation of professional programs. Associate teachers feel a sense of betrayal when their recommendations to fail an under-performing student are not followed by the university. These findings have implications for improving the quality of field experiences and support for students, associate teachers, and faculty in Bachelor of Education programs.

    As healthcare systems demand that nurses be competent in using electronic medical records for patient care, the integration of electronic medical records into nursing curricula has become necessary. The purpose of this study was to explore how students, new nurses, clinical instructors, and faculty perceive the integration of academic electronic medical records into the undergraduate clinical practicum. From January to February 2014, four focus group interviews with 18 participants were conducted based on purposive sampling. Content analysis was used on the unabridged transcripts to extract themes and develop meaningful categories. Three major themes and eight subthemes were revealed from the focus group interviews. The major themes were "electronic medical record as a learning tool for clinical practicum," "essential functions of academic electronic medical records," and "expected outcomes of academic electronic medical record." Participants expected academic electronic medical records to enhance students' nursing informatics competencies. The findings of this study can inform the process of developing academic electronic medical records for clinical practicum, which will then augment students' informatics competencies. PMID:27081757

    This paper reports findings from an ongoing study exploring how the Content Representation (CoRe) design can be used as a tool to help chemistry student teachers begin acquiring the professional knowledge required to become expert chemistry teachers. Phase 2 of the study, reported in this paper, investigated how collaboration with school-based mentors (associate teachers) on teaching practice (practicum) might impact on this process and student teachers' development of their pedagogical content knowledge (PCK). The collaboration involved identifying and discussing pedagogical issues related to a practicum-teaching topic using a student teacher's draft CoRe as a starting point and ongoing focus for the professional dialogue. Practicum offered an opportunity for aspects of student teachers' PCK, as embodied in their draft CoRes, to be explored and expanded upon in classroom programmes with the support and input of associate teachers. The findings were influenced by different contextual factors; however, the student teachers found their CoRes to be very useful frameworks for engaging in focussed professional dialogue with their teaching mentors. They valued the expertise, currency of knowledge and mentoring of their associates and reported positively about the contribution this support made to their PCK development via the CoRe design process and the transformation of the CoRe into classroom teaching.

    Full Text Available The background of the study is a perceived need of increasing quality in practice during Initial Teacher Education (ITE in Sweden. In order to achieve higher quality, the government encourages reorganization towards a limited number of practice schools, competence development for supervisors and research focusing on the selected practice schools.  The aim of this study is to present and critically discuss prerequisites for implementation of the reform. The paper focuses on how a preliminary logic model and a SWOT analysis can show challenges encountered during the implementation of the reorganization. By using the logic model and the SWOT analysis an ex-ante evaluation was carried out in two steps. The results disclosed that the motivation behind reorganization, improving the quality of practicum, might meet some challenges. Indicators of higher quality being attained are not provided; the local organization is expected to construct such indicators during the process. In contrast to the challenges the results showed that the implementation was supported by earlier good relations and a common idea of developing practicum in ITE. The implication for implementation is a need to have a dialogue about indicators for quality among different stakeholders in ITE. Without such a dialogue it can be disputed whether the change in practicum was successful.

    Water is in high demand for farmers regardless of where you go. Unfortunately, farmers in southern Florida have fewer options for water supplies than public users and are often limited to using available supplies from surface and ground water sources which depend in part upon variable weather patterns. There is an interest by the agricultural community about the effect weather has on usable surface water, however, research into viable weather patterns during La Nina and El Nino has yet to be researched. Using rainfall accumulation data from NASA Tropical Rainfall Measurement Mission (TRMM) satellite, this project s purpose was to assess the influence of El Nino and La Nina Oscillations on sea breeze thunderstorm patterns, as well as general rainfall patterns during the summer season in South Florida. Through this research we were able to illustrate the spatial and temporal variations in rainfall accumulation for each oscillation in relation to major agricultural areas. The study period for this project is from 1998, when TRMM was first launched, to 2009. Since sea breezes in Florida typically occur in the months of May through October, these months were chosen to be the months of the study. During this time, there were five periods of El Nino and two periods of La Nina, with a neutral period separating each oscillation. In order to eliminate rainfall from systems other than sea breeze thunderstorms, only days that were conducive to the development of a sea breeze front were selected.

  5. Study of the development of the sea breeze and its micro-scale structure at a coastal site using a Multi-Tone Sodar system

    International Nuclear Information System (INIS)

    The purpose of this paper is to study the development of the coastal flow i.e. its micro-scale characteristics within the surface layer at the sea-land transition and to investigate the development of inland formation of cloudiness during merging of sea/land and valley- mountain breeze regimes. The area is the mountainous southern tip of Italy, about 50 km wide and 300 km long, in the Central Mediterranean Basin. Here, thermal meso-scale circulations and cloud formations on the mountains are pronounced because of their peculiar elongated shape. Upslope flow is very strong, due to the steepness of Apennines, and sea-breeze circulation is supported by the thermally forced meso-scale flows. Here, we present preliminary results from a case study during six consecutive days where sea/land breeze circulation was well developed and discuss the effect on the formation of inland clouds. Sea breeze days are selected by a sodar and surface meteorological station measurements. Cloud development is analyzed by subjective inspection of METEOSAT MSG images in the visible channel. The WRF (Weather Research and Forecasting) model is used to analyze the meteorological situation. The Institute of Atmospheric Sciences and Climate CNR-ISAC in house modular Multi-Tone Sodar system (PC-MTSodar) and the surface meteorological station are installed and operated at a coastal site located at about 300 m from the coastline. Preliminary results show that the methodology is viable to study the development of thermally forced meso-scale circulations over Calabria at micro and large scale and that these circulations can be intense over the peninsula thanks to its peculiar shape. It is shown that the formation of afternoon cumulus clouds, which may result in rainfall, is modulated by synoptic scale conditions. Further development will be a climatic assessment of the role of breezes on local climate

    To prepare future healthcare professionals to collaborate effectively, many universities have developed interprofessional education programs (IPE). Till date, these programs have been mostly courses or clinical simulation experiences. Few attempts have been made to pursue IPE in healthcare clinical settings. This article presents the results of a pilot project in which interprofessional learning activities (ILAs) were implemented during students' professional practicum and discusses the actual and potential use of informatics in the ILA implementation. We conducted a pilot study in four healthcare settings. Our analysis is based on focus group interviews with trainees, clinical supervisors, ILA coordinators, and education managers. Overall, ILAs led to better clarification of roles and understanding of each professional's specific expertise. Informatics was helpful for developing a common language about IPE between trainees and healthcare professionals; opportunities for future application of informatics were noted. Our results support the relevance of ILAs and the value of promoting professional exchanges between students of different professions, both in academia and in the clinical setting. Informatics appears to offer opportunities for networking among students from different professions and for team members' professional development. The use of technology facilitated communication among the participants. PMID:25955721

    2010-02-01

    In the goal of science teacher education, the role of reflection to cultivate the teacher as a transformative practitioner has been largely recognised. Reflective thinking is crucial for teachers to be mindfully and knowledgeably situated in teaching and transforming their actions. This study looks into the dilemmas of teaching practical work in elementary science classes and the roles of reflective thinking. Five preservice teachers, one inservice teacher, and one science teacher educator participated in the process of collaborative reflection (reflective writing on dilemma cases, sharing, and discussing) of teaching practical work during the preservice teachers' practicum. All participants wrote and shared two cases of his/her own dilemmas after teaching or observing lessons with science experiments. Preservice teachers also participated in a survey questionnaire and interviews to share their perspectives of practical work and the process of reflection. Looking into their reflection and discussion on the dilemmas of teaching through science practical work, the study attempts to explore how to make collaborative learning opportunities through reflective thinking. The findings of this study showed that the dilemmas of science practical work emerged in various dimensions of teachers' expectation and classroom interactions. Discussions on dilemma cases could facilitate reflecting and learning from different perspectives among participants. Based on these findings, we further discuss the implication of interactive reflection and discussion on dilemmas of practical work to enhance science teaching and develop collaborative communities in science teacher education.

    Full Text Available After Dewey (1933 and Schön (1983, 1987, education scholars began to look further at the concepts of reflection for learning. Following these concepts, there have been plenty of studies on reflection, particularly those discussing teachers’ classroom experiences and their endeavour to develop professional skills. However, educational practitioners in Indonesia (as in the rest of the world often criticise preservice teachers’ (PSTs lack of content knowledge, which they claim should be ‘prioritised’ during a teacher education course. Such pressing situations may have made it difficult to model or experience reflective practice. Against these odds, this research paper addresses issues related to the identity and professional development of thirteen English PSTs during their campus and school-based practicum in an Indonesian university. This study collected empirical data through PSTs’ reflective journals, questionnaires, individual interviews, focus group discussion, and autobiography. The study examines problems encountered by PSTs, namely their motivations to become teachers. This study signifies that teacher education needs to provide more reflective dialogues to shape PSTs’ identity and professionalism.

    Lack of knowledge and experience is prevalent in undergraduate students who are taking their clinical practicum for mental-health nursing. This issue negatively affects the learning process. This article shares an experience of implementing a practicum-teaching program. This program was developed by the authors to facilitate the cooperative learning and clinical care competence of students. A series of multidimensional teaching activities was designed by integrating the strategies of peer cooperation and creative thinking to promote group and individual learning. Results indicate that the program successfully encouraged the students to participate more actively in the learning process. Additionally, the students demonstrated increased competence in empathetic caring toward patients, stronger friendship relationships with peers, and improved self-growth.

    A simulation study of the sea breeze circulation and thermal internal boundary layer (TIBL) characteristics has been carried out at the tropical site Kalpakkam on the east coast of India, for operational atmospheric dispersion prediction. The community based PSU/NCAR MM5 Mesoscale meteorological model is used for the study. Three cases on typical days in summer (24 May 2003), southwest (SW) monsoon (1 July 2001) winter season (2 February 2003) with different largescale flow pattern are studied. The MM5 model is used with 3 nested domains with horizontal grid resolutions 18 km, 6 km and 2 km and 26 vertical levels. The model is integrated for 24 hours in the above cases with initial and boundary conditions taken from NCEP-FNL analyses data. Observations of 10 meteorological stations and coastal boundary layer experiments conducted at Kalpakkam are used for comparison and validation of the simulation. The characteristics of simulated sea breeze and TIBL at Kalpakkam are seen to vary in the above cases according to the prevailing large-scale winds and surface fluxes. The sea breeze circulation is seen to develop early with larger strength and inland propagation in the summer case under the influence of moderate synoptic wind and strong heating conditions than in the SW monsoon and winter cases. The horizontal and vertical extents of TIBL are found to be larger in the summer case than in other cases. Although model parameters agree in general with observations, all the fine features are not clearly captured and some slowness in model sea breeze development is also seen. The results indicate the need to improve i) the initial conditions by assimilation of available surface/upper air observations to reduce model bias and ii) surface net radiation parameterisation. The model could predict the essential features of the local circulation and further improvement is expected with better initial condition data and incorporation of more realistic surface data.

  15. A study of atmospheric dispersion of radionuclides at a coastal site using a modified Gaussian model and a mesoscale sea breeze model

    Science.gov (United States)

    Venkatesan, R.; Mathiyarasu, R.; Somayaji, K. M.

    Ground level concentration and sky-shine dose due to radioactive emissions from a nuclear power plant at a coastal site have been estimated using the standard Gaussian Plume Model (GPM) and the modified GPM suggested by Misra (Atmospheric Environment 14 (1980) 397), which incorporates fumigation effect under sea breeze condition. The difference in results between these two models is analysed in order to understand their significance and errors that would occur if proper choice were not made. Radioactive sky-shine dose from 41Ar, emitted from a 100 m stack of the nuclear plant is continuously recorded by environmental gamma dose monitors and the data is used to validate the modified GPM. It is observed that the dose values increase by a factor of about 2 times than those of the standard GPM estimates, up to a downwind distance of 6 km during sea breeze hours. In order to examine the dispersion of radioactive effluents in the mesoscale range, a sea breeze model coupled with a particle dispersion model is used. The deposited activity, thyroid dose and sky-shine radioactive dose are simulated for a range of 30 km. In this range, the plume is found to deviate from its straight-line trajectory, as otherwise assumed in GPM. A secondary maximum in the concentration and the sky-shine dose is also observed in the model results. These results are quite significant in realistically estimating the area affected under any unlikely event of an accidental release of radioactivity.

    The highest observed surface ozone concentrations in the Houston metropolitan area in 2013 occurred on September 25, which coincided with the Texas DISCOVER-AQ (Deriving Information on Surface Conditions from Column and Vertically Resolved Observations Relevant to Air Quality) field campaign. Surface ozone was elevated throughout the Houston metropolitan area with maximum 8-hour average ozone peaking along the western shore of Galveston Bay, reaching 124 ppbv, almost 50 ppbv above the current EPA standard of 75 ppbv. The NASA P-3B aircraft observed plumes from refinery flares west and northwest of Galveston Bay that were transported over the water. Continental air pollution from the north was transported into the Houston metropolitan area where it mixed with locally generated emissions. A bay breeze circulation formed causing pollutants that were transported out over the water in the morning to recirculate back inland where they mixed with freshly emitted pollution near the bay breeze convergence zone. The highest surface ozone concentrations were reported near the bay breeze front. This ozone episode will be presented using measurements made during the DISCOVER-AQ field campaign and a CMAQ model simulation with integrated source apportionment, which tracks the contribution of emissions source groups and regions on ozone concentrations.

    2003-04-01

    During the Cooperative LBA Airborne Regional Experiment 2001 (CLAIRE2001, July 2001), we investigated diel variations of nitric oxide (NO), nitrogen dioxide (NO_2), ozone (O_3) and carbon dioxide (CO_2) mixing ratios at Balbina Limnological Station (01^o55'994''S, 59^o28'071''W, Amazonia,Brazil). We applied sensitive and species-specific chemiluminescence (NO, NO_2, O_3) and NDIR (CO_2) analysers to record ambient mixing ratios on 1 min intervals. Simultaneously, we extensively monitored (micro-)meteorological qauntities (air temperature, relative humidity, wind speed and -direction, thermal stratification, rainfall intensity, soil temperatures and moisture, as well as radiation fluxes (global, net, short wave, NO_2 photolysis, and photosynthetic active)). Balbina Limnological Station is located just a few hundred meters south of a 2.360 km^2 hydroelectric power dam (Usina Hidrelétrica de Balbina) and about 100m north from the edge of a primary rainforest. Marked differences in surface albedo and heat storage capacity generate a local wind system, the lake breeze, which advects air from the dam (09:00 to 15:00 local) and from the rainforest (18:00 to 06:00 local), respectively. Generally, we observed marked diel variations of NO, NO_2, O_3, and CO_2 (high/low levels during night/day) and O_3 (low/high levels during night/day). Especially in the tropics, this behaviour is usually related to (a) accumulation of soil emissions (NO, CO_2), chemical reactions (NO, from NO_2-O_3 reaction) and surface destruction (O_3) in a shallow and strong nocturnal boundary layer inversion, and (b) to soil emission (NO), photochemical reactions (NO-NO_2-O_3), dry deposition/plant uptake (NO_2, O_3, and CO_2) and strong turbulent vertical mixing in the daytime mixed layer. However, under the specific conditions of the lake breeze soil emission and dry deposition/ plant uptake can be neglected during daytime. Consequently, the investigation of daytime mixing ratios can be confined to

    2014-01-01

    Universities offering undergraduate degrees in health promotion or health education and/or graduate degrees in public health typically require an internship, practicum, or fieldwork experience. This type of mentored experience is an important aspect of career development for the next generation of public health professionals and benefits not only the students but also the profession and the communities in which they work. This article provides perspectives from four public health professionals who have recently graduated from designated minority-serving institutions and highlights the ways in which internship, practicum, or fieldwork experiences have contributed to their career development. From a career development perspective, internships provide unique opportunities to develop professional networks, practice competencies learned in the classroom, gain experience in different environments, and share lessons learned with others in our field. The diversification of the public health research and practice workforce is increasingly recognized as crucial in building health equity. Internship programs that focus specifically on the academic and professional development of students underrepresented in public health provide experiences that meet or supplement academic requirements, and provide students with real-world experience and an expanded network of mentors and role models.

    2016-01-01

    Full Text Available The Metropolitan Area of São Paulo (MASP is one of the most populated regions of the planet with one of the largest impervious regions as well. This research work aims to characterize MASP heat island (HI effect and its interaction with the local sea breeze (SB inflow in rainfall amounts and deep convection. The combined SB-HI produces direct circulation over the MASP and produces severe weather and socioeconomic impacts. All SB-HI episodes between 2005 and 2008 are identified and analyzed with surface and upper air measurements, weather radar, and satellite data. The current work indicates that intense SB-HI episodes are related to air and dew point temperatures above 30°C and 20°C, respectively, right after the passage of the SB front over MASP. Results indicate that the precipitation related to SB-HI episodes is up to 600 mm or about four times higher than that in rural or less urbanized areas in its surroundings. Measurements indicate that 74% of SB-HI episodes are related to NW winds in earlier afternoon hours. Moving cold fronts in southern Brazil tend to intensify the SB-HI circulation in MASP. A conceptual model of these patterns is presented in this paper.

  5. Study of the thermal internal boundary layer during sea-breeze events in the complex coastal area of Marseille

    Calmet, Isabelle; Mestayer, Patrice

    2016-02-01

    A revisit of two sea-breeze episodes is presented, based on higher spatial resolution large eddy simulations (LES) of the lower atmosphere over the coastal area of Marseille and measurements obtained during the June 2001 experimental campaign UBL-ESCOMPTE. The focus is on the development of thermal internal boundary layers (TIBL) over a complex topography: the dynamic and thermal mechanisms that contribute to the TIBL growth and its further degeneration into a convective mixed layer, the respective influences of the coast shape, the large-scale flow above and the local low-level slope flows. The high-resolution LES permits exploring the potential temperature and turbulent kinetic energy fields in relation with the evolution of TIBL depth and heat fluxes along representative streamlines. Several theoretical TIBL depth models are further compared to the LES-deduced inversion height and other parameters, leading to a discussion of the relationships between the values of these parameters, the respective influences of the governing physical phenomena, and the TIBL behaviour. A threshold value of 0.35 is proposed for the friction velocity to convective velocity scale ratio u */ w * between the two regimes where the TIBL is either dominated by dynamical kinetic energy production or controlled by buoyancy.

    2016-01-01

    We analysed the atmospheric aerosol extinction properties under an influence of inter-seasonal and sea breeze (SB) transport processes over coastal West Bengal (WB) Gangetic plain (WBGP). The predominant frequency of airmass back trajectory path was through the Arabian Sea (AS) during southwest monsoon (SWmon) and that through the Indo-Gangetic plain (IGP) during transition to winter (Twin) season and the Bay of Bengal during transition to summer (Tsumm) season. Aerosol surface concentration (Sconc) and aerosol extinction exhibited heterogeneity in the seasonal variability over coastal WBGP with their highest seasonal mean being during winter and summer seasons respectively. Seasonal mean extinction was respectively 17% and 30% higher during winter and summer seasons than that during SWmon. While angstrom exponent (AE) was less than one during SWmon, Tsumm, and summer seasons, it was near to one during Twin and winter monsoon (Wmon), and was more than one during winter season. Relative contribution (%) of upper (at altitude above 1 km) aerosol layer (UAL) to aerosol extinction during summer was four times of that during winter. Seasonally distinct vertical distribution of aerosol extinction associated with meteorological and SB influenced transport and that due to influence of high rise open burning emissions was inferred. Possible aerosol subtypes extracted during days in Tsumm were inferred to be mostly constituted of dust and polluted dust during daytime, in addition to polluted continental and smoke in UAL during nighttime. In contrast to that at nearby urban location (Kolkata, KOL), intensity of updraft of airmass evaluated during evening/SB activity hour (1730 local time, (LT)) at study site (Kharagpur, KGP) was as high as 3.5 times the intensity during near to noon hour (1130 LT); this intensity was the highest along coast of westBengal-Orissa. Enhanced Sconc and relative contribution of UAL to aerosol extinction (58% compared to 36% only at nearby urban

    Following the high-precision determination of the velocity vector and temperature of the pristine interstellar neutral (ISN) He via a coordinated analysis summarized by McComas et al., we analyzed the Interstellar Boundary Explorer (IBEX) observations of neutral He left out from this analysis. These observations were collected during the ISN observation seasons 2010–2014 and cover the region in the Earth's orbit where the Warm Breeze (WB) persists. We used the same simulation model and a parameter fitting method very similar to that used for the analysis of ISN He. We approximated the parent population of the WB in front of the heliosphere with a homogeneous Maxwell–Boltzmann distribution function and found a temperature of ∼9500 K, an inflow speed of 11.3 km s‑1, and an inflow longitude and latitude in the J2000 ecliptic coordinates 251.°6, 12.°0. The abundance of the WB relative to ISN He is 5.7% and the Mach number is 1.97. The newly determined inflow direction of the WB, the inflow directions of ISN H and ISN He, and the direction to the center of the IBEX Ribbon are almost perfectly co-planar, and this plane coincides within relatively narrow statistical uncertainties with the plane fitted only to the inflow directions of ISN He, ISN H, and the WB. This co-planarity lends support to the hypothesis that the WB is the secondary population of ISN He and that the center of the Ribbon coincides with the direction of the local interstellar magnetic field (ISMF). The common plane for the direction of the inflow of ISN gas, ISN H, the WB, and the local ISMF is given by the normal direction: ecliptic longitude 349.°7 ± 0.°6 and latitude 35.°7 ± 0.6 in the J2000 coordinates, with a correlation coefficient of 0.85.

    Doukakis, Spyros; Koilias, Christos; Chionidou-Moskofoglou, Maria

    During the 2008-2009 spring semester, 25 fourth-year undergraduate primary teachers attended the compulsory course "Teaching Mathematics-Practicum Phase". The course was organised so as to incorporate ICT and special mathematical scenarios in the teaching approaches of undergraduate primary teachers. This article presents course satisfaction of participants as found in the research study. A set of powerful ordinal regression methods has been applied on a survey database. The most important results focus on the determination of the course's weak and strong points, according to the MUSA methodology. The results show a high satisfaction level from the course. The global satisfaction level reaches 98% whereas partial (per criterion) satisfaction levels range from 90% to 97%, the lowest rate corresponding to the theoretical component of the course. The findings raise a number of research questions regarding ICT integration in undergraduate primary teachers' teaching practice.

    The online-coupled Weather Research and Forecasting model with Chemistry (WRFchem) is used to simulate the transport of smoke particles over the Southeast Asian Maritime Continent during September-October 2006. In this period, dry conditions associated with the moderate El Niño event caused the largest regional biomass burning outbreak since 1997. Smoke emission in WRFchem is specified according to the Fire Locating and Modeling of Burning Emissions (FLAMBE) database derived from Moderate Resolution Imaging Spectroradiometer (MODIS) fire products. The modeled smoke transport pathway is found to be consistent with the MODIS true color images and measured mass concentration of surface PM10 (particulate matter with diameter less than 10 μm). The interplay of sea/land breezes, typhoons and storms over the subtropical western Pacific Ocean, trade winds, and topographic effects, can be clearly seen in the model simulation. The most severe smoke events in 1-5 October 2006 are found to be associated with the meteorological responses to the typhoon Xangsane (#18) over the western subtropical Pacific Ocean, which moved smoke from Sumatra eastward in the lower troposphere (below 700 hPa), forming smoke layers mixed with and above the boundary layer clouds over Borneo. In contrast, the second largest week-long smoke transport event of 15-18 October 2006 was associated with the seasonal monsoonal transition period, during which smoke plumes were wide spread over the 5°S-5°N zone as a result of (a) the near surface divergence coupled with the 700 hPa bifurcation of wind (flowing both to the west and to the east), and (b) the near-surface southeasterly and easterly winds along the equator transporting smoke from Borneo to Sumatra and Peninsular Malaysia. Analysis of data from the Cloud-Aerosol Lidar with Orthogonal Polarisation (CALIOP) shows that smoke particles in October 2006 were primarily located within 3.5 km above the surface. Smoke particles contributed roughly half

    The plan of Eole 2005 comes from 50 MW to 77.5 MW and the tariff of buying a wind kWh is coming from 38 centimes to 33.7 centimes (the aim is to bring this industry to economic maturity by successive steps, up to 28 centimes the KWh). With the opening of the great European electric market it is urgent to be competitive because the bar of 8 MW beyond it the private sector is not allowed to compete will be suppressed. The wind power plants will be more powerful but the obligation to buy ( for EDF) will not be topical that is why it is imperative to become competitive for this industry. (N.C.)

    Full Text Available Cartography of the brain ("brain mapping" aims to represent the complexities of the working brain in an understandable and usable way. There are four crucial steps in brain mapping: (1 acquiring data about brain structure and function, (2 transformation of data into a common reference, (3 visualization and interpretation of results, and (4 databasing and archiving. Electrophysiological and functional imaging methods provide information about function of the human brain. A prerequisite for multisubject, multidimensional and multimodal mapping is transformation of individual images to match a standard brain template. To produce brain maps, color, contours, and other visual cues are used to differentiate metabolic rates, electrical field potentials, receptor densities, and other attributes of structure or function. Databases are used to organize and archive data records. By relating the maps to cognitive functions and psychological models, brain mapping offers a prerequisite for the understanding of organizational principles of the human brain.

  17. The mechanism of coking pressure generation I: Effect of high volatile matter coking coal, semi-anthracite and coke breeze on coking pressure and plastic coal layer permeability

    One of the most important aspects of the cokemaking process is to control and restrain the coking pressure since excessive coking pressure tends to lead to operational problems and oven wall damage. Therefore, in order to understand the mechanism of coking pressure generation, the permeability of the plastic coal layer and the coking pressure for the same single coal and the same blended coal were measured and the relationship between them was investigated. Then the 'inert' (pressure modifier) effect of organic additives such as high volatile matter coking coal, semi-anthracite and coke breeze was studied. The coking pressure peak for box charging with more uniform bulk density distribution was higher than that for top charging. It was found that the coking pressure peaks measured at different institutions (NSC and BHPBilliton) by box charging are nearly the same. The addition of high volatile matter coking coal, semi-anthracite and coke breeze to a low volatile matter, high coking pressure coal greatly increased the plastic layer permeability in laboratory experiments and correspondingly decreased the coking pressure. It was found that, high volatile matter coking coal decreases the coking pressure more than semi-anthracite at the same plastic coal layer permeability, which indicates that the coking pressure depends not only on plastic coal layer permeability but also on other factors. Coking pressure is also affected by the contraction behavior of the coke layer near the oven walls and a large contraction decreases the coal bulk density in the oven center and hence the internal gas pressure in the plastic layer. The effect of contraction on coking pressure needs to be investigated further. 33 refs., 18 figs., 5 tabs.

  18. Florida Agriculture - Utilizing TRMM to Analyze Sea Breeze Thunderstorm Patterns During El Nino Southern Oscillations and Their Effects Upon Available Fresh Water for South Florida Agricultural Planning and Management

    Science.gov (United States)

    Billiot, Amanda; Lee, Lucas; McKee, Jake; Cooley, Zachary Clayton; Mitchell, Brandie

    2010-01-01

    This project utilizes Tropical Rainfall Measuring Mission (TRMM) and Landsat satellite data to assess the impact of sea breeze precipitation upon areas of agricultural land use in southern Florida. Water is a critical resource to agriculture, and the availability of water for agricultural use in Florida continues to remain a key issue. Recent projections of statewide water use by 2020 estimate that 9.3 billion gallons of water per day will be demanded, and agriculture represents 47% of this demand (Bronson 2003). Farmers have fewer options for water supplies than public users and are often limited to using available supplies from surface and ground water sources which depend in part upon variable weather patterns. Sea breeze thunderstorms are responsible for much of the rainfall delivered to Florida during the wet season (May-October) and have been recognized as an important overall contributor of rainfall in southern Florida (Almeida 2003). TRMM satellite data was used to analyze how sea breeze-induced thunderstorms during El Nino and La Nina affected interannual patterns of precipitation in southern Florida from 1998-2009. TRMM's Precipitation Radar and Microwave Imager provide data to quantify water vapor in the atmosphere, precipitation rates and intensity, and the distribution of precipitation. Rainfall accumulation data derived from TRMM and other microwave sensors were used to analyze the temporal and spatial variations of rainfall during each phase of the El Nino Southern Oscillation (ENSO). Through the use of TRMM and Landsat, slight variations were observed, but it was determined that neither sea breeze nor total rainfall patterns in South Florida were strongly affected by ENSO during the study period. However, more research is needed to characterize the influence of ENSO on summer weather patterns in South Florida. This research will provide the basis for continued observations and study with the Global Precipitation Measurement Mission.

    Law program in higher vocational college demands extensive practice, and practicum is of great importance to the cultivation of students' professional competency. However, there are deviations in value orientation of practicum of law pro-gram in China's higher vocational colleges:the practicum is marginalized and in lack of uniqueness, the practicum teaching platform is disjointed with the real jobs in society, the coordination mechanism in students fostering is missing, etc. In order to correct the deviations, this paper holds that we should stress on practice instead of theory, focus on non judicial personnel cultivation instead of judicial personnel cultivation, turn from the single and one-way education toward multiple and coordi-nated education, and create own uniqueness in practicum design instead of using the featureless model.%高职法律专业是实践性很强的专业,实践教学对培养学生法律运用能力至关重要。我国高职法律专业实践教学价值取向存在偏离:实践教学被边缘化、选择的实践教学平台与实际就业岗位脱节、实践教学缺乏自身特色、协同育人机制缺失等。纠正偏离需要由重理论向重实践转变、由重司法型人才培养向重非司法型人才培养转变、由单一单向育人向多元协同育人转变、由趋同实践教学向特色实践教学转变。

    Glycogen is a complex glucose polymer found in a variety of tissues, including brain, where it is localized primarily in astrocytes. The small quantity found in brain compared to e.g., liver has led to the understanding that brain glycogen is merely used during hypoglycemia or ischemia....... In this review evidence is brought forward highlighting what has been an emerging understanding in brain energy metabolism: that glycogen is more than just a convenient way to store energy for use in emergencies-it is a highly dynamic molecule with versatile implications in brain function, i.e., synaptic...... activity and memory formation. In line with the great spatiotemporal complexity of the brain and thereof derived focus on the basis for ensuring the availability of the right amount of energy at the right time and place, we here encourage a closer look into the molecular and subcellular mechanisms...

  2. Local scale atmospheric diffusion at a coastal site in the presence of breeze effect (Phase I and II: data collection at a coastal site and off shore)

    International Nuclear Information System (INIS)

    The aim of this contract is the characterization, from the thermal and anemological point of view of the lower layers of the atmosphere at a coastal site, affected by breeze circulation. Data are utilized to set up diffusion models for accidental releases of airborne materials, both of short and prolonged duration. Five inland meteorological campaigns, starting from Jan. 82 (Jan., Apr., Jul., Oct. 1982, Jan. 1983), have been carried out; an appropriate extension of the contract allowed the execution of two more campaigns in the open sea (Apr., Jul. 1983), utilizing the oceanographic ship ''Bannock'' kindly supplied by CNR. The analysis of the data showed the development of a well defined IBL during on-shore flow only in Spring and Summer, while an inversion layer was detectable aloft independently of the season (provided that an anticyclonic situation was present). According to those relevant features a simple diffusion model has been developed for short duration releases at local scale. Finally, the analysis and elaboration of the data, collected on site by a meteorological automatic station, allowed the extension of the model to prolonged releases

    BNCT in the past was not widely accepted because of poor usability of a nuclear reactor as a neutron source. Recently, technical advancements in the accelerator field have made accelerator-based BNCT feasible. Consequently, clinical trials of intractable brain tumors have started using it since 2012. In this review, our clinical results obtained from conventional reactor-based BNCT for treatment of brain tumors are introduced. It is strong hope that accelerator-based BNCT becomes a standard therapy for current intractable brain tumors. (author)

  10. Vertical and horizontal NO2 transport in urban area associated with land-sea breeze as observed by ground-based MAX-DOAS

    Science.gov (United States)

    Takashima, H.; Kanaya, Y.

    2013-12-01

    Since July 2012, continuous NO2 profile observations have been performed by using ground-based Multi-Axis Differential Optical Absorption Spectroscopy (MAX-DOAS) at Fukuoka (33.55N, 130.36E), an urban site in Japan. MAX-DOAS is a passive remote sensing technique using scatted visible and ultraviolet solar radiation at several elevation angles, and it can allow us to retrieve vertical information on several trace gasses. In this study, the vertical resolution of the profiles is roughly 1 km below 2 km height. We investigate inhomogeneity of NO2 over Fukuoka by observing at two azimuth angles, Tenjin (downtown area) direction and Itoshima (out of downtown area) direction. Understanding of the spatial inhomogeneity of NO2 in urban area is important for measuring a priori profiles for satellite and for validating chemical transport model. Diurnal variation with maximum in the morning is clearly observed in both directions throughout the year for 0-1 km. Diurnal variation with maximum around noon is sometimes observed in Itoshima direction, which is delayed by 1-2 hours from maxima in Tenjin direction. The NO2 maximum for upper level (1-2 km) is also delayed from the maximum in Tenjin direction. From the analysis of surface wind field, these variations seems to be strongly related to vertical/horizontal transport of high concentration of NO2 from the downtown area (and development of the boundary layer) and horizontal transport of low concentration from ocean associated with land-sea breeze. We also present a comparison of NO2 data measured with the Ozone Monitoring Instrument (OMI) satellite sensor.

  11. Brain imaging and brain function

    International Nuclear Information System (INIS)

    This book is a survey of the applications of imaging studies of regional cerebral blood flow and metabolism to the investigation of neurological and psychiatric disorders. Contributors review imaging techniques and strategies for measuring regional cerebral blood flow and metabolism, for mapping functional neural systems, and for imaging normal brain functions. They then examine the applications of brain imaging techniques to the study of such neurological and psychiatric disorders as: cerebral ischemia; convulsive disorders; cerebral tumors; Huntington's disease; Alzheimer's disease; depression and other mood disorders. A state-of-the-art report on magnetic resonance imaging of the brain and central nervous system rounds out the book's coverage

  12. Harvesting wind energy from the sea breeze in peri-urban coastal areas by means of small scale wind turbines - Case study: Viladecans, Llobregat Delta, northeast of Iberian Peninsula

    Science.gov (United States)

    Rojas, Jose I.; Cabrera, Barbara; Mazon, Jordi

    2016-04-01

    Wind speed data recorded during 18 years (1993-2010) in the Llobregat Delta (15 km south of Barcelona city; northeast of the Iberian Peninsula) were used to assess the wind energy generated by off-grid small scale wind turbines (the IT-PE-100 and the HP-600W) for the whole year and for the sea breeze period. The computations were made using QBlade, FAST and AeroDyn simulation tools and manufacturer power curves. Using manufacturer data, the HP-600W with hub-height 8 m would deliver 157 kWh during the whole year (78 kWh during the sea breeze period), with an average power of 18 W (37 W). In this work, the results of the simulations are compared with power and energy production data measured in an HP-600W turbine installed in situ from December 2014 to April 2016. Also, the measured power is compared to the power obtained by applying the measured wind in the period 2014-2016 to the manufacturer power curve and the power curve obtained with the simulations. The results of the computations agree with the experimental data, thus validating the proposed approach for wind resource estimation. The feasibility of using a vertical axis wind turbine for obtaining wind energy from the local, thermal wind regimes is also studied. This research confirms that the sea-breeze is an interesting wind energy resource for micro-generation in peri-urban coastal areas where large-scale wind farms cannot be implemented.

    Practicum , directly impacting the quality of teacher education programs , is an important component of teacher education in U . S . A .. Practicum plans developed by American universities are homogeneous in their structures , consisting of the philosophy of practicum evaluation , the evaluation standards and tools , and the methods of evaluation and mentoring . Practicum plans demonstrate the value orientation of US teacher education :laying emphasis on education and development instead of training , and promoting self‐directed learning . These have significant implications for the state‐funded teacher education programs , w hich has been implemented for 8 years , and for the teacher admittance system in our country .%教育实习是美国教师教育体系的重要组成部分,关乎教师教育项目的质量。由美国各个大学自主开发的教育实习方案,其组织结构具有同质化特征,通常由大学的教育实习评价理念、评价标准和工具,以及评价指导办法构成。教育实习方案体现了美国大学注重培养和发展、推动实习教师自我引导的教师教育价值取向。这对反思当下我国已经推行了八年的公费师范教育以及教师准入制度无疑有着借鉴和启示作用。

  14. Brain SPECT

    International Nuclear Information System (INIS)

    Brain SPECT investigations have gained broad acceptance since the introduction of the lipophilic tracer Tc-99m-HMPAO. Depending on equipment and objectives in different departments, the examinations can be divided into three groups: 1. Under normal conditions and standardised patient preparation the 'rest' SPECT can be performed in every department with a tomographic camera. In cerebrovascular disease there is a demand for determination of either the perfusion reserve in reversible ischemia or prognostic values in completed stroke. In cases of dementia, SPECT may yield useful results according to differential diagnosis. Central cerebral system involvement in immunologic disease may be estimated with higher sensitivity than in conventional brain imaging procedures. In psychiatric diseases there is only a relative indication for brain SPECT, since results during recent years have been contradictory and may be derived only in interventional manner. In brain tumor diagnostics SPECT with Tl-201 possibly permits grading. In inflammatory disease, especially in viral encephalitis, SPECT may be used to obtain early diagnosis. Normal pressure hydrocephalus can be distinguished from other forms of dementia and, consequently, the necessity for shunting surgery can be recognised. 2. In departments equipped for emergency cases an 'acute' SPECT can be performed in illnesses with rapid changing symptoms such as different forms of migraine, transient global amnesia, epileptic seizures (so-called 'ictal SPECT') or urgent forms like trauma. 3. In cooperation with several departments brain SPECT can be practised as an interventional procedure in clinical and in scientific studies. (orig./MG)

    尽管国内学者对教师反思实践的理论进行了热烈的探讨,但他们的研究集中于在职教师实践性知识的发展上,甚少涉及学生教师的反思实践。在该研究中,我们设计了反思干预方案,让一群英语教育专业学生教师在实习期间进行小组反思,收集自己的教学点滴,与学校和大学指导老师开三方会议,利用翔实的自我评价表和总结性评价表进行自评和他评。通过分析学生教师实习后的总结日志,我们发现学生教师在实习期间能对教学的各个方面进行不同程度的反思,该反思实践对他们的专业成长起到了促进作用。%Although Chinese educators heatedly have discussed the theories of reflective practices,their research has centered on the development of practical knowledge of in-service teachers and seldom explored the reflective practices of pre-service teachers. In the current study,we designed intervention on reflective practices of student teachers majoring in English education during their practicum. They were required to reflect collectively,collect their teaching data,had meeting with school mentors and university tutors,and self and peer assess their teaching using as pre - designed assessing scheme. Through analysis of 41 student teachers ’ journals written after practicum,the findings shows that the intervention seemed to urge student teachers to reflective different aspects of teaching in a varied degree. In addition, the reflective practices appeared to facilitate student teachers ’ professional development in terms of reflective ability,understanding of teaching,teaching skills and classroom management as well as self-knowledge and understanding of teaching profession.

    Science.gov (United States)

    Torremorell, Maria Carme Boqué; de Nicolás, Montserrat Alguacil; Valls, Mercè Pañellas

    Teacher training at the Blanquerna Faculty of Psychology and Educational and Sports Sciences (FPCEE), in Barcelona, has a long pedagogical tradition based on teaching innovation. Its educational style is characterised by methods focused on the students' involvement and on close collaboration with teaching practice centres. Within a core subject in the Teacher Training diploma course, students were asked to assess different methodological proposals aimed at promoting the development of their personal, social, and professional competences. In the assessment surveys, from a sample of 145 students, scores for variables very satisfactory or satisfactory ranged from 95.8 % to 83.4 % for the entire set of methodological actions under analysis. Data obtained in this first research phase were very useful to design basic training modules for the new Teacher Training Degree. In the second phase (in process), active teachers are asked for their perception on the orientation of the practicum, its connection with the end-of-course assignment, and the in-service student's incidence on innovation processes at school.

Este estudio de caso describe algunas de las oportunidades y desafíos del Practicum Internacional de la Universidad de Salamanca para los aprendices de maestro en colaboración con instituciones educativas del Reino Unido. Más allá de la confrontación viva con la cultura como diversidad, los numerosos agentes implicados en el mismo establecieron un diálogo entre perspectivas pedagógicas diferentes que potenciaron procesos de acción docente colaborativa, interpelación mutua y reflexión conjunta de enorme valor en los ámbitos lingüístico, pedagógico y cultural. Mantenemos que ese diálogo fértil atraviesa fronteras y ya define, en sí mismo, una experiencia educativa de vinculación efectiva por cuanto sitúa la dimensión intercultural en el centro mismo de la trayectoria formativa del profesorado europeo.
