A wavelet based analysis of cosmic rays modulation

Main results of the wavelet analysis and reconstruction suggest that the maximum of Morlet decomposition coefficients was found around the main 11-12 year cycle. However we have found for both solar activity indicator: the sunspot number and modulation potential a dominating period around 12-15 years. Magnitude of cycles is not absolutely the same but vary from cycle to cycle. The attempt of extrapolation has shown other periods of about 20-22, 27-30 years after the year 2007.
