Dangerous regions of blizzard in Georgia

Abstract

Blizzards will do essential damage to the mountain and alpine regions of Georgia. Blizzards especially damages agriculture, is caused the uneven redistribution of snow and are created the bare sections of the pastures, which cause the freezing of winter cultures and the erosion of soil. In the regions, where winter pastures are arranged, blizzards frequently disrupts the normal mode of the feeding of animals and hampers wintering cattle. In this study the observational data of 85 meteorological stations and posts during the period of 1966-2017 are used. Most reliable are data during the period of 1966-1992. In 1993 the majority of alpine meteorological stations were closed; therefore period 1993-2017 was illuminated only by data of separate stations. The materials of the archive of the institute of hydrometeorology of Georgian technical university, data National Environmental Agency, literature data and climatic reference books also were used. Blizzards dangerous regions of Georgia are revealed and the corresponding map of division into districts is built. The dependence of a change in the blizzards on the height of locality is investigated.
