Vertical Structures of Temperature and Salinity in the Southern Taiwan Strait in August, 1997

The vertical structures of temperature and salinity in the southern Taiwan Strait were analyzed based on the CTD data collected during August, 1997. The results are: (1) there exist thermocline and halocline in most of the studied area; (2) the vertical structures of temperature and salinity are complicated in the sea areas south and southeast of the Taiwan Shoal, which is caused by the confluence of different water systems there, but the low temperature and high salinity features of the lower layer water indicate the upwelling in the sea area; (3) the low temperature and high salinity water ascending was found in the lower layer off Quanzhou but didn′t influence the surface layer.
