Change in the Synoptic Regime of Tomsk in the Late 20th–Early 21st Centuries
- 16 Downloads
Synoptic processes that occurred in the Tomsk region between 1993 and 2016 are analyzed. A significant decrease in the difference between the frequency of cyclones and anticyclones over the past decade is revealed. There are tendencies to a decrease in the frequency of Arctic air mass invasion, and to an increase, of subtropical and tropical air masses.
Keywords:synoptic process cyclone anticyclone air mass
