Abstract
A hypothesis is suggested that the forcing synchronizes the climatic processes and manifests itself in the similarity of their essential signs. Orthogonal components are introduced; they differ because of coincidence and noncoincidence of essential signs. The relationship between components can be interpreted as a supply of energy from the Sun, and as an energy sink. For the computation, the algorithms have been developed using the Fourier transform in the basis of trigonometric functions. The theory is applied to decompose the series of the Wolf numbers and temperature from 818 weather stations of the Northern Hemisphere in the range from 1955 to 2010. The new approach characterizes the manifestation of the forcing and corresponds to the well-known notions of natural and climatic processes, so, it is informative, consistent, and suitable for the analysis of series of observations.
