Paper Abstract

The impact of the Atlantic Multidecadal Oscillation (AMO) on the major modes of large-scale atmospheric circulation in the North Atlantic/European Sector in summer is analyzed. It is shown that summer SST anomalies associated with AMO are linked not only to the NAO, but also to East Atlantic/ Western Russia (EAWR) teleconnection pattern. Negative (positive) values of NAO and EAWR indices prevailed in the positive (negative) phase of AMO. The dominance of the opposite phases of NAO, SCAND and EAWR indices in summer during the warm and cooler North Atlantic results in differences in the regional climate. The coupled response of the NAO, EAWR and SCAND is more distinct in the years of extreme AMO index values, what indicates a linearity of the linkage.
