Regional characteristics of annual variation of the oceanic heating to atmosphere
海洋对大气加热场的区域性年变化特征

In this work , the regional characteristics of the annual variations of the heat fluxes released from the ocean to the atmosphere in some tropical and mid-latitude regions are revealed . The climatic mean value of the fluxes appears to vary with annual cycle over low SST regions while with semi-annual cycle over high SST re- gions. Comparing with the flux of turbulent exchange of latent heat and the flux of upward long-wave radiation the flux of sensible heat exchange is very small. Over the high SST regions the value of the latent heat flux is larger and varies with larger amplitudes than that of upward longwave radiations. By contrast, over the low SST regions the two quantities are of similar magnitude and same importance in terms of contribution to the variations of the total heat flux from ocean to atmosphere. While the SST providing a background surface condition , both surface wind and cloud cover play important roles in determining the intensity of the heat flux and its variabilities.
