为探索热带气旋与海洋相互作用,采用国家海洋局南海分局Marex(马瑞克斯)数据浮标实测资料,计算了1986年南海的7个热带气旋海气界面热量交换值.结果表明:热带气旋海气界面热量交换强烈,主要贡献来自潜热通量;热带气旋环流内水温、气温均是下降趋势,气温下降更为明显;夏季热带气旋环流内,感热通量会出现负值,海面有效反射辐射通量出现减弱现象;秋季热带气旋环流内,感热通量和海面有效反射辐射通量显著加强;在热带气旋环流内,海面吸收的短波辐射通量均出现减弱现象;热带气旋环流内受到冷空气影响时,感热变得相当重要,热带气旋表现为对海洋的响应为主.

In order to explore the interaction between the typhoon and the ocean, this paper uses Marex buoy measured data of the South China Sea Branch of the State Oceanic Administration, the heat exchanges at air-sea interaction of seven typhoons in 1986 are calculated using observational data in this paper. It shows that the air-sea interface heat exchange of the typhoon is very strong. The main contribution to the heat is from latent heat fluxes. In the circumfluence of the typhoon, both of the water temperature and the air temperature dropped. The air temperature dropped more obviously. In summer, sensible heat fluxes are negative in the circumfluence of the typhoon, and the net long wave radiation appears to be very weak. But in spring and autumn, the sensible heat fluxes and the net long wave radiation in the circumfluence of the typhoon become stronger. In the circumfluence of the typhoon, absorbing short wave radiation by the sea surface becomes weaker. And the effect from relative humidity on the air-sea interface heat exchange is obviously. When the circumfluence of the typhoon is affected by cold air, the sensible heat has become very important. The main trend is responding to the ocean, as far as typhoon is concerned
