Land breeze is a type of mesoscale circulation developed due to thermal forcing over a heterogeneous landscape. It can contribute to atmospheric dynamic and hydrologic processes through affecting heat and water fluxes on the land-atmosphere interface and generating shallow convective precipitation. If the scale of the landscape heterogeneity is smaller than a certain size, however, the resultin...

A sea-breeze event in south-west Western Australia is simulated using the Regional Atmospheric Modelling System (RAMS) version 6.0. The model is evaluated against high resolution soundings as well as station observations and is shown to reproduce the qualitative features of the sea-breeze well. Sensitivity tests are carried out to investigate the effects of historical land-cover change and chan...

In Guadeloupe (French West Indies), the main municipal solid waste is surrounded by highly urbanized areas. An urban heat island (UHI) behavior has been identified in the landfill environment. It has been measured and its intensity (up to more than 4 C) has been shown to be negatively correlated with nebulosity and Tradewinds strength. Conditions for urban breeze detection have been examined. T...

An analysis of atmospheric gases and particles during periods of land and sea breezes in a coastal city in southwest Mexico indicates limited removal of total particle mass by deposition during periods when the air resides over the ocean. The average PM(2.5) mass concentrations for land and sea breeze samples were 25+/-1.0 and 26+/-1.0 microg m(-3), respectively. The average sum of the ion conc...

A NOAA/Environmental Technology Laboratory Doppler lidar measured the life cycle of the landand seabreeze system at Monterey Bay, California, in 1987, during the Land–Sea Breeze Experiment (LASBEX). On days with offshore synoptic flow, the transition to onshore flow (the sea breeze) was a distinct process easily detected by lidar. Finescale lidar measurements showed the reversal from offshore t...

During July 1964 more than 90 constant volume balloon (tetroon) flights were made from the area of Atlantic City, N.J., with the primary purpose of delineating the sea breeze regime at that locale. The transponder-equipped tetroons were ballasted t o float a t a height of 500 ft., and were tracked by the U.S. Weather Bureau WSR-57 radar at Atlantic City. The tetroon trajectories are compared wi...

In this study, the influence of aerosols, surface roughness length, soil moisture, and synergistic interactions among these factors on tropical convective rainfall focused along a sea breeze front are explored within idealized cloud-resolving modeling simulations using the Regional Atmospheric Modeling System (RAMS). The idealized RAMS domain setup is representative of the coastal Cameroon rain...

introduction shamal winds recognized as a climate regime with a common occurrence in the persian gulf makes periodically adverse weather conditions in this region. among the phenomena occurring under the influence of shamal wind, we can mention dust storms, low-level winds and turbulent marine conditions (rao, 2003). shamal winds are categorized into two types, winter shamal and summer shamal. ...

In coastal cities, the effect of the sea breeze in mitigating the urban heat island (UHI) phenomenon has attracted attention. This study targeted the Fukuoka–Kitakyushu metropolitan area, the fourth largest metropolitan area in Japan which is also coastal. Doppler Light Detection And Ranging (LiDAR) observations were conducted in the summer of 2015 to clarify the transition of the wind field ov...
