SOLAR-RELATED VARIATIONS IN ARCTIC AIR PRESSURE AND LONG-TERM SEA ICE EXTENT IN THE RUSSIAN ARCTIC SEAS DURING SUMMER

A. G. Egorov

The enhancement of solar activity in the solar cycle is accompanied by a long-term decrease in Arctic air pressure at the beginning of the summer season (May—June). During the 16th to 23rd solar cycles, the center of the largest pressure anomalies moves in the north polar region between North America and Eurasia along the polar axis passing through the geomagnetic and geographic poles. The result is a solar-related regulation of air-mass transport over a shallow-water area of Northern Eurasia and long-term changes in the frequency of ice opposition between Russia's western and eastern Arctic seas.
