利用 1999年 8月份的 CTD资料 ,对台湾海峡南部温、盐、密度进行了分析 .分析结果表明 :1)粤东及闽南沿岸的上升流在调查期间较为明显 ,上升流的低温中心位于南澳岛以南区域 ;2 )台湾浅滩东侧在调查期间也存在上升流 ;3)在南澳与台湾浅滩之间海域 ,存在一个来自西南方向的高温、低盐、低密水舌 ,显示此区域受来自粤东沿岸水的影响 .水平方向 ,粤东沿岸水与表层离岸的低温高盐水逐渐混合 ;垂直方向 ,粤东沿岸水影响范围可达 2 0～ 30 m层By using the CTD data investigated in the cruise of August. 1999, temperature, salinity and density in the southern Taiwan Strait were analyzed, and the results indicate that: 1) there is one obvious upwelling along the coasts of eastern Guangdong and southern Fujian, with the low temperature centered to the south of the Nan Ao island; 2) there is another upwelling to the east of Taiwan Shoal; 3) there exists a tongue like current coming from the southwest, i.e. the coast of eastern Guangdong. It has higher temperature, lower salinity and lower density than those in its surroundings. As far as the inshore water of eastern Guangdong, in the horizontal direction, it merges the low temperature, high salinity offshore current gradually; in the vertical direction, it can affect down to 20~30m layer.国家自然科学基金重点项目!( 4 96362 2 0 );; 福建省科技资助项目!( 98- Z- 179
