Studying Snow Structure,

Abstract

In the winters of 1961 - 62 and 1963 - 64 in the territory of the Botanical Garden of the Moscow State University (Lenin Hills), the snow structure was studied. The authors included the observations of the atmospheric precipitation which was falling, and its conversion to a snow layer under the effect of the recrystallization processes. The snowflakes were caught at a height of around 100 m, the photographing was performed with the aid of the camera 'Zenith-S' with the lens Industar-49, which provided a fourfold magnification. The equipment was fastened on a special support of the device for the microphotography, MFA-7 the photographing was done on a film with a sensitivity of 180 units with exposures of 0.5 - 1.5 seconds in daylight.
