Abstract

Based on the data of long-term instrumental observations of precipitation, the average long-term indicators (norms) and linear trends for the period 1966-2021 were calculated. Maps of the distribution of precipitation anomalies for each month and season were constructed. Linear trends of precipitation anomalies were calculated for the entire territory of Russia as well as for individual physical and geographical regions, such as the European part of Russia, Western Siberia, and the Far East. Based on the wavelet and cross-wavelet analysis, characteristic cycles of variability of atmospheric fluctuations were revealed and close connection and the coherence of fluctuations of atmospheric fluctuations with dangerous climatic indices were determined.
