台湾海峡南部1999年8月温、盐、密度的分析

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）粤东及闽南沿岩的上或流在调查期间为明显，上升注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，显示地区域受来自粤东沿岸水的影响、粤东沿岩水与表层离岩的低温高盐水逐渐混合，垂直方向，粤东沿岩水影响范围可达20－30m层。

Analysis on Temperature, Salinity and Density in the Southern Taiwan Strait in August, 1999

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.
