| Summary: | <!--!introduction!--> The study of the climatic characteristics and annual runoff of the Volga and Severnaya Dvina rivers demonstrates that on the East European Plain (EEP), Early Twentieth Century Warming (ETCW) manifested in a multiyear drought between 1934 and 1940; this drought has no analog in this region in terms of intensity and duration according to Palmer’s classification and caused extreme hydrological events. The circulation conditions during this event were characterized by an extensive anticyclone over Eastern Europe, combined with a cyclonic anomaly in the circumpolar region. An analysis of the spatial features of sea surface temperature (SST) anomalies indicates that the surface air temperature (SAT) anomalies in July on the EEP during ETCW were related not only to the North Atlantic (NA) warming and positive Atlantic Multidecadal Oscillation (AMO) phase, but also to a certain spatial pattern of SST anomalies characteristic of the 1920–1950 period.
