Effect of Warm Atlantic Waters on the Climate Anomalies in the West Arctic

Abstract

Significant climatic changes of oceanic and atmospheric elements and a relation of them to the ocean surface winter anomalies in North Atlantic are analyzed in the paper. Periods of «warm» ocean (2002–2012) and «cold» ocean (1960–1970) were determined. Positive anomalies of the ocean surface temperature increase the ice-free water area and, correspondingly, decrease the ice-field area. As a result of such changes in a state of the ocean surface (open water and ice), surface air temperature rises, and, consequently, atmospheric pressure in central part of a given Arctic sector drops.
