Project: Extraterrestrial effects on atmospheric circulation in mid and high latitudes

The ongoing project, in which we have shown that solar and geomagnetic activity statistically significantly affect some aspects of the Northern Hemisphere tropospheric circulation, stimulated new scientific questions, answers to which are the basis of the proposed project. Investigated will be effects of solar and geomagnetic activity on further characteristics of tropospheric circulation, i.a. cyclone positions and tracks, blockings, circulation regimes; various classifications of atmospheric circulation; basic circulation characteristics in the Southern Hemisphere; reconstructed circulation indices over Europe back to the beginning of the 18th century. We will also study tropospheric effects of strong geomagnetic storms, energetic solar protons, and relativistic electrons, and interactions of solar and geomagnetic activity with the ENSO, QBO, and stratospheric vortex. Theoretical and numerical models of downward controls of the upper atmosphere will be verified on the observed data.
