The possible reasons of hot Russian summer 2010

The satellite data and complex comparison with results of the analysis of the climatic and paleodata has allowed to assume that the combination of several natural factors has served as the causes of hot summer in Russia (change of a phase of long-term oscillations of CA, El-Nino), led to unusually long blocking of the western wind. The similar cause has led to cold winters 2009/10 and 2010/11: the winter Siberian maximum replacing summer Asian depression, Canadian maximum and Arctic anticyclone have provoked a blocking situation, which has blocked the warm Atlantic air access. We already noticed that last years the reper points (line) of latitudinal structure of a radio thermal field of a planet - its different signs extrema - are displaced to the north. It seems that the situation of last year is defined not by any extraordinary events, but long-term (in multi-decadal scales) atmosphere fluctuation on which phase change we now are (this fluctuation is traced in indexes of atmospheric centers of action). The prevailing type of the atmospheric circulation which have led the anomaly heat summer, dominated the last winter and has remained in the next that causes fears that the heat can repeat the next summer of 2011.
Keywords: general circulation of atmosphere, the centers of action of atmosphere, multi-decadal atmospheric oscillations, climate change
