为探索南海与季风相互作用,用观测资料,计算了1986年南海季风海气界面热量交换值.结果:南海夏季风爆发及其控制南海时,位于(20.49°N,114.14°E)附近海域,在热带辐合带和热带气旋系统内,海气界面热量交换强烈,潜热迅速跃升,1986年5月23日在台风系统内,感热出现正值,海洋向大气输送热量是主要现象,主要贡献来自潜热.夏季风控制南海天气晴好时,海面温度虽然较高,感热却出现负值,大气向海洋输送热量是主要现象,主要贡献来自海面吸收的短波辐射和感热,结果与闫俊岳等的不同.夏季风结束后,南海受东北季风控制时,海气界面热量交换非常强烈,南海对大气加热是主要现象,主要贡献来自潜热,冷空气到达海面时,感热量值迅速跃升均为正值.结论:南海海气界面热量交换的变化与海面温度变化趋势不一致,季风控制南海时,南海对夏季风响应为主.
In order to explore the interaction between the South China Sea and the monsoon, the heat exchange values of the SCS monsoon interface in 1986 were calculated by observational data.Results: When the onset of the South China Sea summer monsoon and its control over the South China Sea are located in the sea near (20.49 ° N, 114.14 ° E) In the tropical convergence zone and the tropical cyclone system, the heat exchange at the air-sea interface is intense and the latent heat rapidly increases. Positive values of sensible heat appear on the typhoon system on May 23, 1986, and the ocean is the main contributor to the heat transfer from the ocean to the atmosphere. The main contribution Summer monsoon control When the weather in the South China Sea is fine, the sea surface temperature is high, but the sensible heat is negative. The atmospheric transport of heat to the ocean is the main phenomenon. The main contribution comes from the shortwave radiation and sensible heat absorbed by the sea surface. When the South China Sea was controlled by the northeast monsoon, the heat exchange at the sea-air interface was very strong after the summer monsoon. The South China Sea heating the atmosphere was the main phenomenon, with the main contribution from the latent heat. When the cold air arrived at the sea surface, the sensible heat value rapidly jumped to a positive value .Conclusion: The change of heat exchange in the South China Sea is not consistent with the change of sea surface temperature. When the monsoon control the South China Sea, the South China Sea mainly responds to the summer monsoon.
