Contemporary Climate Change and Its Hydrological Consequence in the Volga Federal District, European Russia

An analysis of spatiotemporal variability air temperature and precipitation in the Volga Federal District (European Russia) between 1966 2021 was carried out. Based on data from 20 meteorological stations, relatively evenly located territory under consideration, spatial distribution average monthly annual temperatures assessed; some indicators temporal these variables period consideration were calculated analyzed. It revealed that throughout District, there a tendency climate warming all months, slight increase precipitation, except for southeast district, where trend negative. is noted 1955–1998, number negative anomalies approximately equal to positive ones; however, later 1999–2021, significantly exceeded ones. reanalysis data, climatic maps vaporization runoff during 1966–2021 created. The dependence fluctuations nature atmospheric circulation using NAO, AO, SCAND indices. On example central part district (Republic Tatarstan), summer aridity by Budyko’s dryness index, Selyaninov’s hydrothermal coefficient, Sapozhnikov’s humidification coefficient. evaporation also methods Schreiber Ivanov. Against background rates, favorable conditions decrease noted.
