本文依据1984年7月的实测水文资料和卫星图片,指出了南黄海西部存在着因潮混合形成的浅水陆架锋,分析了陆架锋区的水文结构,指出在冷水团锋面区域海洋上层存在着一个因下层冷水上升而形成的低温、高盐、高氧带,沿陆架锋及冷水团边界区域,是黄海的主要上升流区。本文还指出,夏季黄海沿岸流主要是一支沿黄海冷水团锋面南下的强流(jet)。在冷水团衰退时期,随着冷水团的退缩,这一沿锋面的流动将向外海推移。
Based on the measured hydrological data and satellite images in July 1984, this paper pointed out that there is a shallow water shelf front formed by tidal mixing in the western part of the southern Yellow Sea, and analyzed the hydrological structure of the front of the shelf. It is pointed out that there is a The low-temperature, high-salt and high-oxygen zones formed by the rise of the lower cold water are the main upwelling areas along the shelf front and cold water mass boundaries. It is also pointed out in this paper that the summer Yellow Sea coast flow is mainly a jet flowing southward along the front of the Yellow Sea cold water mass. During the recession of the cold water mass, as the cold water mass shrinks, the flow along the frontal surface will shift to the open sea.
