Interannual Variability of the Heat Exchange of the Ocean and the Atmosphere in the Arctic

Research of annual total heat flow variability in the Arctic region formed by the interaction between Ocean and Atmosphere is executed. It’s made on the basis of average monthly values of sea ice closeness and thickness, salinity and sea surface temperature and also air temperature at the level of weather shelter and skin temperature of a snow-ice cover, zonal and meridional wind velocity components during 1969–2012. Heat flow through a snow-ice cover is calculated in the assumption of linearity of a temperature profile between its upper and bottom boundaries. Heat exchange on the water surface is defined by the equation expressing proportionality of incoming and outgoing heat to product of wind velocity and difference between water and air temperature. The estimation error of the heat flow value at changing of the skin temperature of a snow-ice cover by the air temperature at the level of a weather shelter is made. The analysis of heat flow fluctuations correspondence with the Arctic Oscillation index is carried out.
