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.
