| 摘 要： | 讨论了铅直向叠置 3层水团 ,即次表层水团、次 中层混合水团和中层水团的分布与水团特征。改进了大洋性次表层水团和中层水团隶属函数的拟合方法 ,并进一步提出包络曲线法用以拟合次 中层混合水团的隶属函数 ,使铅直向叠置 3层水团隶属函数的拟合方法得以配套。应用新方法计算了 3层水团在南海全海域的分布 ,从整体上把握了次表层高盐水团、次 中层混合水团和中层低盐水团在南海中的分布及变化情况 ,讨论了它们的特征、差异和形成原因。

| Abstract: | In this paper, an analysis is made of the distribution and the characteristics of the three vertically located water masses, i.e. the Subsurface Water Mass, the Subsurface-Intermediate Water Mass and the Intermediate Water Mass. Some improvements on the fitting methods of the membership functions of the oceanic Subsurface Water Mass and the Intermediate Water Mass are made, and then a new method, i.e. the Envelope Curve Method is presented to fit the membership function of the Subsurface-Intermediate Water Mass, thus, in combination with the other two, forming a complete set for fitting the membership functions of the three water masses. These new methods are then used to calculate the distribution of the three relevant water masses in the entire area of the South China Sea and a general status of distribution and variability of these water masses is outlined. Furthermore, also discussed their characters, differences and formation. |
