摘要：According to the observation of 20 meteorological stations of Georgia the number of days, duration and intensity of blizzards were investigated. The distribution of common, low snowstorms and snow drifting have been analyzed. The number of days of a snowstorm increases with the height of the terrain and in the highland zone of the Caucasus, for the year in average reaches 80-100 days, and on the South Georgian Highlands – 70 days. The largest number of days, respectively, is 150 and 80 days. Formulas for calculating the annual number of days with blizzards, depending on the height of the terrain in various mountain areas, are obtained. The total duration of blizzards for the year depends on the number of days with blizzards. Their longest duration is noted in the high mountain zone, where the number of days with blizzards exceeds 100, and is more than 1000 hours. Blizzards are most intense in the ridge part of the Greater Caucasus (maximum intensity 4-5 points). In the high-mountain zone of the South Georgian Highlands, on the Likh and Adzhar-Imereti ridges, the intensity of a snowstorm is 3-4 points. In the mountainous regions of Georgia, mostly snowstorms with an intensity of 2 points prevail, their probability exceeds 60 %, with the exception of the Gagra Range, where weak snowstorms with an intensity of 1 point prevail.
