Abstract
We explore possible causes for time variations in the long-period effects of solar activity (SA) and variations in galactic cosmic rays (GCRs) on the circulation of the lower atmosphere. It is shown that the observed variations in the amplitude and sign of the SA/GCR effects are closely related to the evolution of the circumpolar vortex forming in the high-latitude stratosphere.
