Abstract

An impact of global warming on river runoff into the Arctic seas is discussed. River runoff is one of the main components of the Arctic freshwater balance. Annual total river runoff is determined as the sum of runoff of six rivers: the Ob, Yenisei, Lena, Kolyma, Indigirka, and Mackenzie. The indices of zonal, meridional, and general circulation were calculated to assess the effect of atmospheric circulation. Correlations between the indices and surface air temperature and precipitation in the catchment areas confirmed the most significant influence of atmospheric transport on climatic conditions in the cold season. It was stated that annual total river runoff increased during 1979-2019, but the occurrence of peak discharges was reduced.
