1　引言由于地球表面热通量直接决定着大气环流运动 ,在大气数值模式中如何准确描述地球表面热通量就变处得十分重要 .洋面是地球表面最广泛分布的下垫面 ,它的表面热通量描述尤为被重视 .尤其是西赤道太平洋暖池、东赤道太平洋冷舌、ＩＴＣＺ及信风带等关键区域的洋面热通量的 1 INTRODUCTION As the heat flux of the Earth’s surface directly determines the general circulation of the earth’s surface, it is very important how to accurately describe the heat flux of the earth’s surface in the atmosphere numerical model. The ocean surface is the most widely distributed underlying surface of the earth, The description of surface heat flux is of particular importance, especially for the ocean surface heat flux in the key areas of the western equatorial Pacific warm pool, the eastern equatorial Pacific cold tongue, the ITCZ ​​and the letter wind zone
