Two Types Of The Surface Pressure Oscillations In The Extra-tropical Zone Of The Northern Hemisphere Depending On Long-term Variations Of Solar Activity

摘要

The increased solar cycle activity is followed by long-term anomalies in the surface air pressure that take place in the extra-tropical zone of the Northern Hemisphere in winter. The most important peculiarity is an opposite change in the pressure in the regions that tend to the Icelandic and Aleutian lows. During the 16th-23rd solar activity cycles, two scenarios of pressure change in the high latitudes are observed: (1) an increase at the border between the Arctic and Atlantic Ocean and a decrease at the border with the Pacific; (2) a decrease at the Arctic border with the Atlantic Ocean and an increase at its border with the Pacific. Spatial-temporal peculiarities of natural oscillations adapted to large-scale inhomogeneity in land and ocean distribution in the temperate and high latitudes and, therefore, the Arctic hydrometeorological conditions can be considered as important indicators of solar-terrestrial relations.
