CURRENT FEATURES OF THE CIRCULATION TERMS OF FORMATION OF THE THERMAL REGIME ON THE TERRITORY OF UKRAINE
The research is devoted to modern features of circulation in the troposphere and stratosphere, which cause sharp increase and decrease in air temperature in Ukraine. The circulatory processes of the troposphere and stratosphere, as well as the factors that determine them, are complex, their intercon...

The research is devoted to modern features of circulation in the troposphere and stratosphere, which cause sharp increase and decrease in air temperature in Ukraine. The circulatory processes of the troposphere and stratosphere, as well as the factors that determine them, are complex, their interconnections are ambiguous and often asynchronous. At the same time, one can not but admit that modern atmospheric circulation changes also require a detailed study and analysis. Because modern features of circulation on the one hand have become one of the factors of changes in the modern climate, and on the other hand, they themselves have changed due to global climate change.In the proposed study, on the basis of statistical analysis of the repetition of extreme values of the average daily air temperature and atmospheric pressure in January, April, July and October for two periods corresponding to the end of the 20th and early 21st centuries, an attempt was made to find out the features of the state of stratospheric polar vortices affecting the duration and intensity of the waves of heat and cold in our country.The results of the study indicate that the current change in the circulation conditions of the study area, namely the movement of the influence of atmospheric centers, leads to increased extremes of climatic conditions, in particular, the thermal regime.
