Relation between variations in the characteristics of the high-latitude atmosphere and solar cosmic factors

Daily temperatures at high latitudes of the Northern and Southern hemispheres and the corresponding levels of currents of solar protons and the PC , Ap , and Dst magnetic indices are considered. The character of variations in the surface temperature depending on these indices in different seasons du...

Description
Summary:	Daily temperatures at high latitudes of the Northern and Southern hemispheres and the corresponding levels of currents of solar protons and the PC , Ap , and Dst magnetic indices are considered. The character of variations in the surface temperature depending on these indices in different seasons during strong magnetic storms, when the Dst amplitude was smaller than −50, has been indicated. The relationship of the indices in southern and northern atmospheric oscillations (SOI and NAO) to the Ap indices has been revealed. The monthly average Ap amplitude increases before the El Nino warm period, when the SOI index decreases from 0 to −1.5 and the NAO index increases from −0.5 to 0.9. The La Nina cold period, when SOI increases from −0.1 to 1.3 and NAO decreases from 0.7 to −0.45, begins after a decrease in the Ap index.
