The Warm Winter in the Russian Arctic and Anomalous Cold in Europe

摘要

Considered are synoptic mechanisms of the formation of abnormally warm weather and high anticyclones in the Russian Arctic as well as the generation of the series of cold cyclones in the middle troposphere over southern Europe in January-February 2012. Obtained are the typical schemes of thermobaric fields of the macro-scale reconstruction of atmospheric circulation and of the set-in of the eastern air transport from Siberia to the central and southern areas of the European part of Russia and to the Mediterranean countries. Proposed is an algorithm for predicting processes of atmospheric blocking with the help of quantitative criteria that enable to assess the existence, intensity, and lifetime of the circulation impeding the westerlies.
