The paper shows the relation of the dynamics of the geomagnetic activity Kp-index with annual distributions of high-speed solar wind fluxes and coronal mass ejection. It is shown that near the maxima of solar activity, the average annual number of coronal mass ejection ~ 8 times (the average value for 20 - 23 cycles) exceeds the number of high-speed fluxes, during these periods the average annual values of the Kp-index are formed by coronal mass ejection. It is shown that during the decay phase of solar activity, the average annual number of high-speed fluxes is ~ 6 times (the average value for 20 - 23 cycles) exceeds the number of coronal mass ejection, during these periods the average annual values of Kp-index are formed by solar wind high-speed fluxes. To pick out seasonal variations in the work, an analysis of the intra-annual distributions of the Kp-index diurnal values is carried out. The annual distribution of the number of cases (years) according to the type of seasonal variations (strong variations, minor and irregular changes) is very uneven and varies from cycle to cycle, depends little on the phase of the solar cycle and does not depend on the direction of the Sun magnetic field. During 7 solar cycles (83 years), strong seasonal variations are observed in 34 cases (41% of the total), no variations for 15 cases (18%). The average values of the Kp-index variations for each phase of the solar cycle are obtained. The relation seasonal variations in outer radiation belt relativistic electron fluxes and the duration of the outer radiation belt energetic electron precipitation in the ionosphere with seasonal variations of the Kp-index is shown.
