| 摘 要： | 根据1996年初春中韩黄海水循环动力学合作调查所获资料,分析了南黄海水文特征及其环流状况,并获得了以下几点主要认识:(1)初春南黄海的温、盐分布特征及环流基本形态,与以往所揭示的冬季状况基本相似.然而,本次调查发现,在30m以浅,黄海中部暖水舌轴线比冬季的明显偏东;且出现一范围较小的孤立的相对高温高盐区.在垂向,一种中层冷水和表层逆温跃层现象出现在黄海局部区域.(2)直接测流的结果,不仅部分地印证了由温、盐场所显示的环流基本形态,而且较好地揭示了流场中发生的一些新现象,其中尤其是绕济州岛的流动.(3)黄海暖流水是对马暖流水和陆架水混合而成.而且,它主要是在济州岛西侧水域,从锋带中衍生出来的.

| Abstract: | Hydrographic features and circulation situation in the southern Huanghai Sea (SHS) are studied on the basis of the data obtained by China-Korea Joint investigation of Ocean Circulation Dynamics in the SHS in the early spring of 1996. The main results are as follows: (1 ) The temperature-salinity characteristics and the basic circulation pattern in the SHS in the early spring are basically similar to those in winter revealed in the past. However, it is found in this investigation that the axis of the warm water tongue in the middle Huanghai Sea is obviously to the east as compared with wintertime situation and a small-range isolated water they with relatively high temperature and salinity appears in this region. Meanwhile, a middle-layer cold water and a surface inversion layer occur in the local regionS of the SHS; (2) the results of direct current measurements not only verify the basic pattern of the circulation showing by temperature-salinity distributions, but also reveal much better some new phenomena occurring in the current field, espeCially the current around Cheju-do; (3) the Huanghai Warm Current water is a mixture of the Tsushima Warm Current water and the continental shelf water and originates mainly from the frontal region west of Cheju-do. |
