The article discusses some aspects of interaction between atmospheric dynamics processes in the Arctic and the mid-latitudes under conditions of global climate change and rapid warming in the Arctic in the lower layer of the troposphere (due to a mechanism of positive feedbacks, enhancement of atmospheric heat and moisture fluxes to the Arctic and heat transfer by currents in the ocean). This is a difficult task, given the fact that the observation of this phenomenon is relatively short. One of the plausible physical hypotheses of the effect of warming in the Arctic on the dynamics of the atmosphere in the mid- and high latitudes is that the reduction of sea ice and snow cover anomalies caused by this warming can lead to changes in the frequency and intensity of the extreme weather events and large-scale circulation in the mid-latitudes and in the Arctic region. Polar cyclones, stratospheric vortex, jet streams, North Atlantic oscillations - these objects of atmospheric dynamics are the subject of discussion in this article. The paper also presents the results of a study of the sensitivity of the Arctic Ocean and the sea ice to variability of atmospheric circulation, taking into account the dynamics of the NAO/AO. Special attention is paid to the circulation over the Norwegian and Greenland Seas, which are the area of formation of the initial trajectory of distribution of Atlantic waters in the Arctic Ocean.
