THE VERTICAL STRUCTURE OF SUMMER FOG IN THE DICKSON ISLAND REGION
Abstract
IN July-August 1957 a number of meteorographs on moored balloons at two points, Dickson Island and Tadibe-Yakha were used to study the vertical structure of the atmosphere during sea and monsoon fogs. Results of t e inve tigations at Dickson Island are given. Meteorograph ascents to a height of 500 m were made every two hours with five-minute stops at 25, 50, 100, 15 , 200, 300, 400, and 500 m. The most favorable conditions for the development of sea fog were in Arctic air (AA) masses transferred from the Kara Sea. Monsoon fog developed with polar air (PA) movement above a cold ea surface. Under Dickson Island conditions, this could occur only with winds directed along the shore. Fog in AA masse us ally develops in anticyclones. As a rule, there is no fog in PA masses in the Dickson Island region; evidently it is formed over the sea at some distance from the coast. (Author)
