Description

Data of Bx, By, Bz components of the Interplanetary Magnetic Field (IMF) have been used to study a features of the IMF turbulences for two positive (A>0) and two negative (A<0) polarity epochs of solar magnetic cycles (1969-2011). We found that the changes of the exponents vy, νz, νx of the Power Spectral Density (PSD) of the By, Bz, Bx components of the IMF show a radical alternation of the large–scale structure of the IMF turbulence in period 1969-2011. We found a distinction between the temporal changes of the exponents vy, νz, νx for the A>0 and the A<0 polarity epochs of solar magnetic cycles, especially in minima and near minima epochs of solar activity. We suppose that the changes of the turbulence in the range of frequencies [10^(-6)-10^(-5)]Hz (responsible for the scattering of the GCR particles of the energy 5-50 GeV) and the module B of the IMF versus solar activity can be considered as the general reasons of the long period variations of the GCR intensity.
