对2009年5月中沙群岛附近海域的水文观测资料,运用垂向梯度法,计算了中沙群岛海区温度及盐度两种跃层所处的深度及各自的厚度和强度,并进行了相应的分析。结果表明,夏季风转换期间海洋表、底层温度分布南高北低,表、底层盐度分布较为均匀;垂直结构上温度跃层比较稳定,无逆跃层出现;盐度跃层基本为单跃层,但在研究区南部混合层以下出现两种盐度异常水体。
Using the vertical gradient method, the hydrological data of the waters around the Zhongsha Archipelago in May 2009 were used to calculate the depth and the thickness and intensity of the two thermocline in the sea area of the Zhongsha Archipelago. Analysis. The results show that during the summer monsoon transition, the temperature distribution in the bottom of the oceanic table is lower in the south and lower in the north, and the distribution of salinity in the table and the bottom is more uniform. The thermocline in the vertical structure is relatively stable with no reverse layer, and the salinity thermocline is basically a single jump However, there are two kinds of abnormal salinity water below the mixing layer in the southern part of the study area.
