Comparative analysis of short-term effects of solar and galactic cosmic rays on the evolution of baric systems at middle latitudes

Proceedings of the 34th All-Russian Conference on Cosmic Rays

Abstract

Effects of solar proton events (SPEs) and Forbush decreases of galactic cosmic rays (GCRs) on the evolution of baric systems at middle latitudes are compared. It is shown that SPEs with particle energies >90МeV contribute to more intensive regeneration of cyclones at Arctic fronts, while Forbush decreases of GCRs are accompanied by intensification of anticyclonic processes at Polar fronts. The data show that changes in the ionization rate caused by cosmic ray variations play an important part in solar-atmospheric relationships.
