Spectral analysis of variations in cosmic rays, solar activity parameters, and the interplanetary medium

Resumo

The periodicities of cosmic rays in the stratosphere, in the neutron component, and in different parameters of solar activity and the interplanetary medium between 1965 and 2015 are studied by means of spectral analysis. The data are analyzed separately according to cycles of solar activity. A shift of spectral components is observed in the even–odd combination of solar activity cycles.
