| Summary: | Abstract Results of numerical of coupled numerical experiments with 3D atmospheric general circulation model, upper layer ocean model and sea ice evolution model are carried out and discussed for Arctic region. Model calculations to analyze sea ice cover evolution are carried out. Calculated sea ice cover distributions for different seasons are presented. Sea ice cover sensitivity analysis to base models parameters, determining atmosphere, ocean and ice interaction, sensible heat flux from sea ice and snow surface, heat flux from ocean to ice is presented. The spatial and seasonal structure of changes has rather complex non-uniform character, there are great areas of opposite changes. It is connected with nonlinear behavior of feedback and interactions in model system including an atmosphere, sea ice and ocean.
