Carried out are the statistical analysis of spatiotemporal characteristics of quasistationary and blocking anticyclones in the Atlantic European sector, their classification, and the analysis of large-scale circulation in the lower and middle troposphere preceding the formation of different classes of blocking anticyclones. Studied are the threshold conditions of anticyclone blocking in the lower and middle troposphere in the Atlantic European sector. Determined are the typical situations, when the formed dipoles of heat and cold are observed in the area of the future blocking in the lower troposphere as well as the formed ridges or divergence of flows in the middle troposphere. A conclusion can be made on the possibility of using the information about blocking anticyclones in the schemes of long-range forecasting of thermal regime
