FEATURES OF TEMPERATURE AND HUMIDITY REGIME OVER THE NORTH ATLANTIC: 850 MB GEOPOTENTIAL HEIGHT.IN THE COLD PERIOD
Problem Statement and Purpose. Formation of hydrometeorological characteristics at 850 liPa level is governed with the processes of interaction of the underlying surface with the surface layer of air and. at the same time, processes in the middle troposphere. Such processes assume the presence of in...
