Abstract

The paper presents the results of analyzing the variability of the main meteorological quantities characterizing the state of the lower troposphere over Siberia (50°–70° N, 60°–110° E). The variability of the values and anomalies corresponding to the scales of high-frequency, synoptic, and low-frequency variability, as well as the characteristics of cyclones and anticyclones has been analyzed for different seasons. It has been found that cyclones have become deeper, anticyclones have become higher, and the duration of the presence of the pressure systems over the study region has decreased. Significant high estimates of correlations between the vortex processes in the troposphere over Siberia and variations in anomalies of the main meteorological characteristics are manifested mainly on the scales of high-frequency and synoptic variability in the spring and summer season at levels up to 850 hPa.
