摘    要:根据国家海洋局南海分局的Marex(马瑞克斯)数据浮标观测资料、南海断面线 调查资料和西沙海洋站资料,计算了南海海气界面热量交换值。研究结果表明:不论是夏季还是秋季,在台风环流内海气界面热量交换均非常强烈,主要贡献来自潜热通量(Qv),位于(20.49°N,114.14°E)附近海域。夏季台风环流内显热通量(Qk)出现负值,海面有效反射辐射(Qe)出现减弱现象;秋冬季节台风环流内Qk量值增加显著均为正值,Qe有加强的现象。分析实测资料发现:1961~1989年8次ElNino事件过程中,西沙海洋站水温比赤道太平洋水温提早出现增暖现象的有4次,水温推迟出现增暖现象的也是4次。西沙海洋站水温增暖出现在12月的仅有1次。ElNino事件发生后,南海水温异常增暖,但是海气界面热量交换反而减弱。

关 键 词:南海    台风    热量交换

Abstract:On the basis of data collected by the South China Sea Branch Marex buoy, science research of the South China ocean and obversation station on Xisha, we computed the value of air-sea heat exchange over the South China sea. The research results show that in the circumfluence of the ty phoon, the air-sea heat exchange is very strong in summer and autumn. The main contribution to the heat is from latent heat fluxes (Qv). In summer, there is negative sensible heat fluxes (Qk) near the ocean of (20.49°N, 114.4°E), and the net long wave radiation appears to be very weak. But in autumn and winter, in the same area, the sensible heat fluxes (Q k ) is added so much that its value becomes posi tive. At the same time, the net long-wave radiation (Qc) becomes stronger in the two seasons than that in summer. Analysing the data from the SST of Xisha, we can find that in the eight El Niino events of 1961 to 1989, there are four El Nino events during which SST of Xisha became warm earlier than that of the equatorial Pacific and the other four El Nino events during which the SST of the Xisha became warm later than SST of the equatorial Pacific. There was only one event during which the SST in Xisha became warm in December. When El Nino occurred, the sea surface temperature of the South China Sea became warmer. However, the air-sea heat exchange became weaker.
