- Abstract
In this work we continue studying possible reasons for a roughly 60-year periodicity in the evolution of correlation links between pressure in the lower atmosphere and solar activity. New data providing evidence for influence of the atmospheric circulation regime on the formation of effects of solar activity (galactic cosmic ray fluxes) on tropospheric pressure variations (the development of extratropical baric systems) are presented. It is shown that, in turn, changes in the circulation regime are associated with variations of the intensity of the stratospheric polar vortex, which are also characterized by a ∼60-year periodicity. Dominant harmonics with periods of ∼80 and ∼60 years were revealed in variations of total solar irradiance according to the updated Hoyt–Schatten reconstruction. This allows us to consider variations of solar irradiance as one of possible reasons for changes in the state of the polar vortex and the corresponding changes in large-scale circulation.
