The change of the circulation of the atmosphere exerts a significant influence on the formation of weather conditions. Depending on the duration and intensity of the latitudinal or longitudinal types of atmospheric circulation can be formed in periods of extreme weather and climatic characteristics. The aim of this work is the estimation of the reasons of occurrence of the area of dangerous hydrometeorological phenomena and the analysis of the circulation processes, leading to the establishment of extreme weather conditions in the region.Using the calendar of the consistent changes of elementary circulation mechanisms and daily observations of the weather in the south of Central Black Earth region (by the example of Belgorod region). The total frequency of occurrence of stationary anticyclones over the European part of Russia (with the continuous duration of 6 days or more) has increased both in summer and winter periods. The scheme of development of the circulation processes leads to an increase in the frequency of extreme high temperatures, natural fires, soil and atmospheric droughts. During the period under review such a dangerous agrometeorological phenomena as «soil drought» was observed for the first time. Given the size of the synoptic facilities, hazardous hydrometeorological events should be expected at the same time in several subjects of the Federation. The most vulnerable sectors of the national economy are agriculture, housing and communal services and transport. © 2014 AENSI Publisher All rights reserved.
