Abstract:

The variability of the characteristics of cyclones and anticyclones (number, pressure at the center (hPa), and duration (days)) and their trajectories is studied for Siberia (50–70 N, 60–110 E) in different seasons throughout the climatically significant time interval 1976–2018 on the basis of surface synoptic maps. It is found that the number of baric formations has increased, the pressure at the centers of cyclones has decreased and at the centers of anticyclones increased, and the duration of cyclones and anticyclones has decreased during the period under study. These trends in the behavior of the characteristics of cyclones and anticyclones are especially pronounced at the end of the period. During the year, the anticyclonic weather was observed more often than cyclonic in Siberia.

Keywords:

season, Siberia, cyclones, anticyclones, number, average pressure at the center, duration of baric formations
