摘　　要：采用实测资料计算1986年7—12月东海和南海观测海域海-气界面热量交换。结果表明:7—9月上旬,大气向观测海域输送热量是主要现象,因为这时的气温比水温高,潜热通量与感热通量出现反相变化,天气晴好,海洋大量吸热;9月中旬—12月,观测海域向大气输送热量是主要现象,东海表现得比南海更为明显,主要贡献来自潜热通量和感热通量。受冷空气影响时,感热通量重要;在热带辐合带和热带气旋系统内海-气界面热量交换强烈,大气对海洋的响应为主。Based on the data in selected areas of the East China Sea（ECS） and the South China Sea（SCS） observed from July to December 1986, the study attempts to calculate the air-sea heat exchange over the sea surface. The results showed that heat is mostly transferred from the atmosphere to the ocean over the East China Sea and the South China Sea during the period from July to the first ten days of September, because the air temperature is higher than the water temperature, latent heat flux changes anti-phased with sensible heat flux, and the weather is fine and the ocean absorbs a large amount of heat. And heat is mostly transferred from the observed area to the atmosphere during the period from the middle ten days of September to December. This kind of phenomenon is more obvious in ECS, where latent and sensible heat fluxes are the main contribution, than in SCS. Sensible heat flux is more important when it is affected by cold air current. Inside the Intertropical Convergence Zone（ITCZ） and tropical cyclone systems, the air-sea heat exchange is very intense and responses to the ocean exerted by the ITCZ and the tropical cyclone play a key role during the time. Next are our conclusions. For the heat exchange between the air and the sea over the observed sea areas of ECS and SCS in 1986, it is more intense from July to the first ten days of September than from the middle ten days of September to December; the air-sea exchange is more intense in ECS than in SCS; and in the ITCZ and tropical cyclone systems the air-sea heat exchange over both of the observed areas is intense.
