摘    要:用一个简单的海洋模式,研究了东亚季风异常对南海表层水温(SST)的影响,发现南海表层水温的甚低频振荡是东亚季风异常风应力强迫所致.这种甚低频振荡主要反映在深水区,其空间分布呈椭圆形,几乎与南海海盆形状一致。从海盆中央到边缘振幅逐渐减少,SST的甚低频振荡是非行进波,无明显传播特征。

关 键 词:南海  表层水温  甚低频振荡,深海区,东亚季风异常

Abstract:Using a simple ocean model, the effect of anomalous Asian Monsoon upon she SST of the South China Sea is studied. It is found that the SST low frequency oscillation of the South China Sea is induced by the anomaly wind stress of the Asian Monsoon. The SST low frequency oscillation is mainly concentrated in the depths.The spacial distribution of the SST low frequency oscillation is of elliptical type,which is in accordance with the shape of the South China Sea basin. The amplititude of the SST low frequency oscillation decreases from the basin center to the edge. The SST low frequency oscillation is of nonpropagation type.
Keywords:South China Sea  SST  low frequency oscillation  deep sea area  anomaly of the Asian Monsoon
