Abstract

© Published under licence by IOP Publishing Ltd. Climate and weather extremes observed in the Volga Federal Region (VFR) are studied in relation to the climatic changes taking place in the XX - XXI centuries. Weather observation data from 183 meteorological stations and ERA5 reanalysis data are used as a source material. It has been demonstrated that a significant jump in the annual temperature mean was registered, the number of large-scale positive anomalies exceeded the number of negative ones, the quantity of hot days grew, while the quantity of ice days dropped in the VFR at the turn of the XXI century. The dynamics of hazardous weather events (strong winds, convection phenomena) was characterized by a positive trend on the territory of the VFR within the period from 1991 to 2018.
