Abstract : Solar activity, expressed by cycles of different orders, exerts an enormous influence on processes in the earth's troposphere, in each specific physiographic region creating definite climatic conditions with a definite variability. The mechanism of interaction between solar activity and the earth's atmosphere is still unknown. Accordingly, the problem of long-range heliophysical forecasting must be solved in the opposite direction, considering any climatic element as the final result of a complex mechanism of solar-terrestrial interaction. Under various physiographic conditions and in each specific year the mechanism of helioclimatic interactions is manifested differently, in dependence on the height of the maximum of the 11-year cycle and its evenness. Each even and odd 11-year cycle forms double 22-year cycle making up the principal 44-year cycles, having the most regular alternation of high and low values. Helioclimatic relationships are determined by using the method of superposing of epochs. (Author)
