Variability of Arctic and North Atlantic sea ice: A combined analysis of model results and observations from 1978 to 2001
Ice cover data simulated by a coupled sea ice-oceanmodel of the North Atlantic and the Arctic Ocean are compared withsatellite observations for the period 1978 to 2001. The capability ofthe model in reproducing the long-term mean state and the inter-seasonalvariability is demonstrated. The main mode...
