台湾海峡南部二测站1997年8月温、盐垂直分布的时间变化

Time Series Variation of Vertical Distributions of Temperature and Salinity in Two Anchored Stations in Southern Taiwan Strait in August, 1997

根据台湾海峡南部 ２ 个定点多周日观测站 １９９７ 年 ８ 月的 Ｃ Ｔ Ｄ 资料，进行温、盐垂直分布时间变化的分析，结果表明：二测站调查期间基本上都存在温、盐跃层，跃层的强度和深度随时间变化较大，显示出较为复杂的温、盐垂直分布，与多种水系在此交汇有关．但二测站的下层稳定地存在低温高盐的海水，有向上涌升的趋势，并受潮流的影响。

Time series variations of the vertical temperature and salinity distributions in two anchored stations in the southern Taiwan Strait have been analysed based on the CTD data during August, 1997. The results are: (1) there existed thermocline and halocline in the sea areas around two anchored staions, the strength and depth of which varied pronouncedly from time to time because of the interaction among the currents there; (2) low temperature and high salinity water can appear in the lower layer of the two studied stations, which was affected by the tidal currents,indicating the existence of the upwelling there.
