- Аннотация: A model of the joint circulation of the North Atlantic, the Arctic Ocean, and the Bering Sea is presented with the resolution of 0.25° in latitude and longitude. The numerical technique of solving this problem and the organization of numerical experiments are described. Numerical calculations have been performed using this model for the period of 1958–2006. The results are compared with observation data and with the results of simulation by other models. Model estimates of the evolution of the Atlantic water incoming into the Arctic basin through the Fram Strait and the Barents Sea are presented. A positive trend of Atlantic water incoming into the Arctic basin through the Fram Strait is revealed. The evolution of the fresh water layer thickness in the Beaufort Gyre is considered. Three periods of increased thickness correlated with increased anticyclonic vorticity are pointed out: 1960s, 1980s, and the period from 1999 until now. The evolution of the anticyclonic vorticity is ahead of the changes in the fresh water layer thickness by 1.75 years. Long-term positive trends of fresh water layer thickness and the anticyclonic field vorticity in the Beaufort Gyre have been observed from the middle of 1970s. This period is characterized by a negative model trend of the ice area in the Arctic, which corresponds to observation data.
