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
The temperature, salt and density in the southern Taiwan Strait were analyzed using CTD data from August 1999. The results showed that: 1) the upwelling of the eastern Guangdong and southern Fujian coasts was more obvious during the survey period, and the low temperature center of the updraft was located in Nan’ao Island 2) there is also an upwelling during the survey on the east side of Taiwan’s Shoal; 3) there is a high-temperature, low-salinity, low-density water tongue from southwest in the sea area between South Australia and Taiwan Shoal, indicating that this area is affected by In the horizontal direction, the water from the eastern Guangdong coast gradually mixes with the low-temperature and high-salinity offshore water from the surface; in the vertical direction, the influence of water along the eastern Guangdong coast reaches 20 to 30 m
