Description
Summary:The formation of the fields of surface winds over the Black Sea occurs under the action of numerous physical factors. One of the most important factors is the monsoon mechanism connected with the seasonal variations of buoyancy contrasts over the sea and surrounding land. To separate the effects caused by this mechanism, we performed and described the numerical experiments aimed at the evaluation of the sensitivity of the regional model of atmospheric circulation to the variations of land–sea temperature contrasts. It is shown that the influence of these effects is restricted to the lower part of the atmosphere. The presented estimates of the climatic fields of disturbances enable us to describe the monsoon mechanism specifying the seasonal variability of the field of vorticity of the wind velocities and, as a consequence, the seasonal variability of the large-scale circulation of waters in the Black Sea.
