Characteristics of troposphere moisture, jet streams and wind shifts in the formation of small-scale eddies in the Black Sea region
Presented is an analysis of the humidity characteristics and dynamic characteristics of the troposphere in the course of origination of small-scale vortices associated with cyclonic activity in the Black Sea region. It is shown that in all cases of dangerous phenomena an increase of the moisture content in the Earth - 825 hPa layer is observed; in dates with tornados, the moisture content is 1.5-2.0 times higher than in cases without them, the upper boundary of the layer with an increased moisture content reaches the 600 hPa surface. In the lower layers of the troposphere in dates with small-scale eddies wind intensification is observed twice: at the surface of the Earth and in the layer of 700-600 hPa, at the same altitudes, there is also a wind shear.
