摘要

This work is aimed at studying circulation conditions of the abnormally cold winter of 2005-2006 over Siberia where the intensification of meridian air exchange was accompanied by a frequent invasion of cold air masses into temperate latitudes and their precipitation in lower layers of troposphere. Stratospheric warming and long-term blocking processes in troposphere over Europe and Yakutia preceded the development of deep high-latitude cyclones over Siberia and the Urals. High-latitude convergence over Siberia was accompanied by a strong cyclonic wind shift and intensification of jet stream. On the whole, weakening of western transfer within the significant layer of atmosphere, decrease of a number of deep cyclones in the Western Arctic, as well as stratospheric warming create a high level of predictability of short-period climatic changes over Siberia in winter.
