Abstract The paper describes a coupled regional model of the atmosphere and ocean. The modeling domain includes the Arctic Ocean, the peripheral seas of Eurasia and North America, and land regions up to 50° N. The oceanic and atmospheric modules of the model are independent and exchange data according to an established protocol through a developed interactive information exchange system (communicator). The model aims at scenario projection of future climate change in the atmosphere and ocean on timescales from several weeks to a century. Reanalysis data are used to specify initial and boundary conditions for the model. An analysis of the results of regional climate simulations for 1993–2012 is carried out. It is shown that the developed model is generally able to reproduce an observed state of the Arctic climate system, however, significant uncertainties in regional observations make it difficult to unambiguously evaluate the quality of model simulations.
