A study of the dynamics of the Northern Eurasia and the Arctic basin climatic systemclimate dynamics, mathematical modeling.

This paper studies the dynamics of the Northern Eurasia climate under conditions of the global climate change based on a coupled atmosphere and ocean general circulation models. The estimation and the analysis of a feedback for some parameters of the atmosphere are done. The role of the biosphere in the climate dynamics of the 21-st century is investigated, with allowance for the structure of the surface layer, the vegetation layer, soil and the hydrology dynamics. The main features of the dynamics of the North Atlantic and the Arctic ocean in the periods appropriate to various phases of an index of the North-Atlantic Oscillations (NAO) are investigated.
