| 摘 要： | 本文分析了济州岛南部区域温度双跃层现象的类型及其成因。特别阐明了双跃层的波状现象,指出:强流锋区的侧向效应,黑潮次—中层混合水的爬升,黄海冷水团边缘密度环流引起的侧向流动,以及上、下层流速、流向不一致引起的剪切作用,是导致双跃层波状现象的主要原因。发现上、下跃层之间存在着“跃层间环流”,这是一个有趣的海洋学现象,它将导致双扩散的发生和有利于双跃层的维持。

| Abstract: | The types and the causes of the double-thermocline discovered south of Chejudo Island are analysed. Here we explain specially its wavelike phenomenon. It is pointed out that the main causes of this phenomenon are led by the lateral effect in strong current front area, the climbing of the Kuroshio Subsurface- Intermediate Mixed Water, the sidewise current induced by the density circulation around the Yellow Sea Cold Water Mass and the shear effect induced by the difference of current speeds and current directions between the upper layer and the lower layer.It is also discovered that there is an inter-thermocline circulation in the double-thermocline, which is an interesting oceanographic phenomenon. It will lead double-deffusion to generate and favour the maintaince of double-thermocline. |
