On the description of the 11- and 22-year cycles in the GCR intensity

The time profiles of the galactic cosmic ray intensity near the Earth are considered. We try to reproduce the main features of these profiles by solving the usual boundary–value problem with the transport equation and rather simple models of its coefficients. Only the "normal" 22-year cycl...

Description
Summary:The time profiles of the galactic cosmic ray intensity near the Earth are considered. We try to reproduce the main features of these profiles by solving the usual boundary–value problem with the transport equation and rather simple models of its coefficients. Only the "normal" 22-year cycle consisting of the pair of the successive 11-year cycles in the GCR intensity (1980-2000) is discussed. Besides, we suggest the method to decompose the intensity into the partial "intensities" connected with the main physical processes.
