Abstract

Changes of general atmospheric circulation of the northern hemisphere in the second half of the 20th century were studied using Dzerdzeyevsky typification. Principal changes might have begun in the 40's - 50's with the increasing circulation instability and cyclogenesis intensification above Artic regions. Cyclogenesis intensification was accompanied by increasing recurrence of meridional circulation forms. In the second half of the 70's some activity decay of synoptic processes began, and in the 80's a new rise occurred. The changes started in the 40's - 50's are probably a part of global changes since at the same time the deepening of circumantarctic depression and circulation intensification began in the southern hemisphere.
