Anomalous conditions of the inflow to reservoirs of the Volga-Kama cascade in the autumn-winter of 2019/2020

Abstract

The peculiarities of the inflow regime to the reservoirs of the Volga-Kama cascade in the autumn-winter of 2019/20 are considered. Based on the analysis of long-term characteristics for the entire period of operation of the cascade, an assessment of the anomalous excess of inflow in October-March 2019/20 is given. The relationship between the autumn-winter inflow to the cascade and the autumn and winter circulation, particularly the phase of the wintertime Arctic oscillation on the background of a positive air temperature trend is shown.
