Characteristic Features of Energy Exchange Between Sea and Atmosphere in the Black Sea Coastal Zone in Summer

G. V. Surkova, P. A. Toropov, and S. S. Mukhametov

Characteristic features of energy exchange between sea and atmosphere in the coastal zone are considered with allowance for the wind direction in the surface layer and at 500 hPa in the summertime. Principal characteristics of distributions of the energy-exchange parameters are found. It is demonstrated that large-scale air flows directed from the land in the daytime are accompanied by increased stability of the marine surface layer, decreased sensible heat fluxes, and evaporation intensification. In the nighttime, on the contrary, such tendencies are observed when flows at 500 hPa are directed from the sea. When mesoscale circulation with surface wind directed parallel to the large-scale flow is developed, the sensible heat transfer increases both in the daytime and at night, while the evaporation increases in the nighttime and decreases in the daytime.
