Abstrakt: We investigated long-term changes of the main trajectories of extratropical cyclones in the North Atlantic. It was found that the average latitudes of cyclone trajectories in the cold half of the year undergo oscillations with the periods of ∼80–90 and ∼22 years, which indicates their possible connection with solar activity cycles. A possible mechanism of the detected effects involves changes in the intensity of the stratospheric polar vortex due to variations of galactic cosmic ray fluxes. [ABSTRACT FROM AUTHOR]
