Long-term variations of circulation and temperature regime in the atmosphere over Siberia have been studied against the background of the global climate variations. General atmospheric circulation is presented by B.L. Dzerdzeevskii typification. It is shown that the intensification of cyclogenesis above Arctic in the second half of the 20th century is accompanied by an increase of temperature in the Northern hemisphere, especially, starting from the 80s. The change of atmospheric processes in the Arctic manifests itself in variations of the regional climate as well. In the past decade, most noticeable growth of the near ground air temperature is observed in winter.
