Hydrometeorological Hazards in the Volga Federal District

Abstract

The major air temperature anomalies and extreme hydrometeorological phenomena on the territory of the Volga Federal District against a background of the current climate change are analyzed using weather station data and ERA5 reanalysis. A trend is revealed towards a decrease in the annual number of days with minimum temperature below -20°C and towards an increase in the annual number of days with temperature above 25°C. The severe weather events registered in the Republic of Tatarstan and the Udmurt Republic in 1973-2018 are presented as examples. An increase in air temperature extremes in the Volga Federal District and in the frequency of hydrometeorological hazards is observed. The negative consequences of the 2010 heat for the Tatarstan population health are considered.
