Snow cover

The village of Teba, Mezhdurechensk district , Kemerovo region , Russia. The height of the snow cover is 1 meter 80 cm.

Snow cover - a layer of snow on the surface of the Earth , formed as a result of snowfalls and blizzards. In Russia, the maximum snow cover thickness (up to 7 meters) is observed in the spring in the Caucasus, on the Lago-Naki plateau (not taking into account the cases of avalanche feeding and snowstorm transport, when the thickness can greatly exceed these values) ^[1] . The snowiest settlement in Russia is the village of Pushchino in the Kamchatka Territory. In the Volga region, the maximum snow height (up to 1.5 meters) is observed in the capital of the Republic of Tatarstan, in Siberia (up to 1.8 meters) in the Kemerovo region, in the central Rudnik, in the Urals, the maximum snow depth is noted in Perm (up to 111 cm), in the Polar Urals in Vorkuta, up to 2 meters. The smallest snow-covered city in Russia is the capital of the Astrakhan region, where the maximum possible snow depth is 37 cm, in Siberia the smallest snow region is the Trans-Baikal Territory, and in Chita, in the entire history of measurements, the maximum snow depth is 47 cm. The minimum average number of days in a year with snow snow cover in Russia (9) is observed in Sochi, on Cape Chelyuskin and the Arctic islands of eastern Russia, snow cover is up to 11.5 months a year and, in fact, does not have time to completely melt, since it takes 20-25 to completely melt snow it.

Snow cover has a low density, increasing over time, especially in spring. Reflectivity ( albedo ) of freshly fallen snow - 70–90%, of old, melting snow - 30–40%.

Snow cover strongly reflects solar radiation , but protects the soil from excessive cooling, and winter crops from freezing; has a huge impact on climate, terrain, the nutrition of rivers and glaciers, soil-forming processes , the life of plants and animals. At the same time, the snow cover can lead to the plant growing, which in Western Siberia , according to a study in the 1960s, 133 species of trees and shrubs out of 630 studied were exposed. The reason for this phenomenon was established by Soviet scientists in the late 1980s ^[2] .

Distinguish:

temporary snow cover melting several hours or days after formation;
stable snow cover that persists throughout the winter or with short breaks.
