Abstract

We compared changes in the latitudinal position of the main trajectories (storm tracks) of extratropical cyclones in the North Atlantic with the magnetic Hale cycle on the Sun. It was shown that bidecadal oscillations in latitudes of storm tracks are due to a northward shift of cyclone trajectories during the descending phase of even 11-year cycles, when the intensity of galactic cosmic ray fluxes is higher compared with that in odd cycles. The obtained results suggest an important part of cosmic rays in solar-climatic links.
