Climate change in the Arctic: causes and mechanisms
Abstract Atmospheric heat and moisture transfers from the North Atlantic make the main contribution to the Arctic warming in winter. The increase in transfer is associated with changes in atmospheric circulation in the Northern Hemisphere under the influence of the sea surface temperature (SST) in l...

Abstract Atmospheric heat and moisture transfers from the North Atlantic make the main contribution to the Arctic warming in winter.
