regional climate change

Introduction. The work is devoted to the analysis of the influence of different states of the circumpolar vortex on local features of the geopotential fields, which, in turn, determine the variability of cold season precipitation for the studied territory of Western Siberia. Data and Methods. A statistical analysis of time series of seasonally average values of the precipitation amount in the cold season was performed, obtained from 33 meteorological stations located within the selected coordinate area.

In this article it is shown that on the background of the second wave of the global warming on the territory of Saratov and the region is well noticeable climate change, especially in the multiyear averages, mean monthly temperatures, as well as the duration of the main and the transitional seasons of the year. Noted the contribution of the circulation in the formation of the climatic characteristics of the region
