The numerical results obtained have shown that the dynamic atmosphere factor plays an important role in changing the state of the ice cover. A change in the Atlantic water pathway has an influence on the ice depth in the regions of the Barents Sea, the Fram Strait and the Eurasian shelf slope. The numerical results have shown the reduced ice depth in this region with strengthening the cyclonic wind circulation in the Norwegian and the Greenland seas, and increased ice depth with weakening the cyclonic wind circulation. However it is impossible to say that this dependence is direct, after five years the physical processes proceeding outside the Arctic begin their effect on state of the ice cover.
