Аннотация:Dependences of air-sea energy exchange parameters on the direction of surface and 500 hPa wind in summer are investigated for the coastal zone. Main characteristics of distribution functions are computed. It is shown that large-scale off shore winds in day-time is followed by increasing of stability in surface layer above the sea, decreasing of heat fluxes and intensification of evaporation. In night-time, on the contrary, such tendency is typical for on-shore fluxes at 500 hPa. Under mesoscale circulation influence as well as when they coincide in surface layer with large-scale wind direction heat fluxes increase both in day-time and in the night, evaporation is stronger in night and weaker in day-time.
Analyzed parameters determine intensity of heat and vapour air-sea exchanges and influences on the structure of the atmosphere boundary layer. It is shown the in coastal zone continent influences on the vertical profiles of air temperature and humidity above the sea and is followed by intensification of exchanges processes between atmosphere and sea. Important role of mesoscale atmosphere circulations as a mechanism of this influence is shown.
