Historical data on thermal regime and sea ice covering the Arctic basin show that natural climate in the North Polar area is liable to a cyclic character. G.Ya.Vangengeim stated that large-scale atmospheric circulation in the Northern hemisphere depends, basically, on three causes: 1) localization of cyclonic circumpolar gyre; 2) localization of arctic anticyclone; and, 3) propagation of long thermobaric waves in low stratosphere. Dynamics of this complex influence on the polar climate in Russian hydrometeorology is usually estimated by means of classification of predominant forms of atmospheric transfer i.e.: W – western, E – eastern and C – meridian ones. Following base of data was put for estimation of climatic tendencies in the Arctic region characterizing, first of all, 1) distributions of absolute values and anomalies of average monthly air surface temperature on the Northern hemisphere for a period from 1891 to 2007 in a grid of 50 per 100 km space step; and, secondly, 2) distributions of average mon
