Regarding the offshore extension of the sea breeze circulation, the results of EXP3 Fig. Synoptically speaking, the NE monsoon synoptic winds which blow from NE to SW oppose the local sea breeze circulation. In Fort Lauderdale, we see a conditionally unstable environment up to about mb and a strong sea breeze circulation at 1PM in Figure 5. This results in a frequent occurrence of the sea breeze, especially during the maturation period in February Bonnardot, ; when land temperatures are high mean February temperature is 22C at Cape Town airport and the ocean remains cool due the cold Benguela current below 15C in some places.

A Theoretical Consideration For Sea Breeze Circulation In Peninsular India
Even though the sea breeze penetrates up to at least the edge of the study domain more or less km inland , the effect on relative humidity and temperature decreases rapidly with distance from the coast. For more information, visit the cookies page. Automatic weather stations situated in vineyards to determine mesoclimatic effects are invaluable for the validation of such data. In extreme cases the whole Sea-Breeze circulation may be transported over the sea. The sea breeze, therefore, combined with the prevailing flow and penetrated inland to at least the edge of the study domain Fig7b.
Sea breezes and thunderstorms
The cold air from the sea meets the warmer air from the land and creates a boundary like a shallow cold front. We now make the important assumption that the vertical distribution of the heating is approximated by Here the subscript, , refers to values at surface anemometer level; the exponent, , is an empirical constant. Monthly Weather Review, Vol. For example, during a sea breeze event, a coastline with a concave shape will lead to divergent winds. The image below is a scheme of the vertical extent of the U-component of the See Breeze from this study.
This scheme is depicted in the image above, top left. Meanwhile, along the coast adjacent to the eastern Gulf of Finland the wind field is more divergent and no clouds are produced. Weaker onshore winds however can change into a developing Sea Breeze front. A simplified overview is provided using the following model. Numerical simulation of the air movement over the Western Cape was performed on a 5 km grid.
