circumpolar vortex

The influence of circulation factors on the quantity of atmospheric precipitation in the cold season in Western Siberia

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.
