Abstract : During a 1956 expedition, 11 vertical soundings of ogs, 45 soundings of stratus clouds and 21 soundings of stratocumulus clouds were made. The accumulated experimental data allow us to draw some preliminary conclusions as to the nature of the structure and development of low cloud cover and fog in the eastern part of the western sector of the Soviet Arctic in the fall. All expeditionary flights were made north of 7 degrees n, primarily along the coastal strip of the Ob-Yenisei region an along the western coast of the taimyr Peninsula. All flights were made above either an open water surface and/or coastal tundra partially covered by snow. In most cases, the flight paths lay over a water surface partially c vered with ice. most observations were made at subfreezing te peratures (fro 0 to -10 C), therefore, as a rule, t e cloud were supercooled. Half of the observations made in fogs were also made at subfreezing temperatures. (Author)
