Аннотация:Extreme precipitation in summer is classified in terms of be long in to the certain base line probability distribution. The Pareto distribution can be used as its approximation. Synoptic objects in which super-large precipitation anomalies occur are determined: these are cyclones or pressure troughs with high water vapor content in the air (exceeding ~25 kg/m2) and with mesoscale systems embedded into the fronts, which are characterized by the vertical wind shear.
