主要根据近几年来中韩黄海水循环动力学合作调查结果,结合有关历史资料,对南黄海环流的若干特征进行了分析.所得主要认识为:(1)南黄海环流存在明显的季节变异.冬、夏季环流的基本形态有着较大的差别.(2)黄海暖流的路径和强度均有一定的年际变化.分析显示,1997年冬季,暖流路径明显偏于槽的西侧;而1986年冬,暖流的主流路径则沿槽北上.(3)黄海暖流并非对马暖流的直接分支.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海域,从锋区中衍生出来的.(4)夏季黄海表、底层环流大致皆是由一大的道时针向流系构成.但在其表层海盐尺度的气旋式环流内部还存在小的气旋和反气旋流环.分析亦表明,不论表层或底层,皆无高盐暖水从济州岛邻近海域进入黄海东部的明显迹象.
According to the results of Yellow River SEA hydrodynamic cooperation survey in recent years and some historical data, some characteristics of the circulation in the South Yellow Sea are analyzed. The main findings are as follows: (1) There are obvious seasonal variations in the circulation of the South Yellow Sea. Winter and summer the basic form of circulation has a big difference. (2) Both the path and intensity of the Yellow Sea warm current have some interannual variations. Analysis shows that in the winter of 1997, the warm current path is obviously deviated to the west of the trough. In the winter of 1986, the mainstream of warm current flows along the trough north. (3) The Yellow Sea warm current is not a direct branch of the warm horse. The Yellow Sea warm water is a mixture of horse warm water and shelf water. Moreover, it is mainly derived from the front area in the western waters of Jeju Island. (4) Summer Yellow Sea Table, the bottom of the circulation are generally composed of a large time-lag flow system. However, there are still small cyclone and anticyclone circulation inside the cyclonic circulation on the surface sea-salt scale. The analysis also shows that there are no obvious signs of entering the eastern Yellow Sea from the waters near Jeju Island in either the surface or the bottom.
