Changes of the streamflow of northern river basins of Siberia and their teleconnections to climate patterns
Abstract The Arctic rivers contribute more than one‐third of the total freshwater streamflow into the Arctic Ocean and play an essential role in the heat and mass circulation of the Arctic atmosphere/ocean system. As the Arctic is warming faster than the global average, the streamflow from Arctic ba...
