The marine meteorological data collected with the vessel "Xiangyanghong No. 14, China" and other ships have been used in this study to evaluate net radiation, latent and sensible heat exchanges, and the net heat gain by the sea surface. It is shown that the measure of the net heat gain by the sea surface is related to the increase and reduction of the Equatorical Convergence Zone. Meanwhile, the heat fluxes transfer from sea surface to atmosphere would be by means of the latent heat.This study has also emphasized that the supporting atmosphere energy from sea surface may take place on the tropical zone of the West Pacific (by 10 °N) rather than on the equatorical zone during this investigation, February 8-14, 1986.
