| 摘 要： | 本文第一作者早在1985年就提出,潮混合效应控制着夏季黄海冷水团的边界及海面冷水分布(赵保仁,1985)。1987年又进一步通过水文调査资料和卫星图片给出了黄海周围的浅水陆架锋(或称潮汐锋)的分布及强锋区的跨锋断面中的温度、盐度和坏流结构特征,并指出夏季的黄海沿岸流在性质上属沿锋面运动的强流(赵保仁,1987a,b),而后又对黄海西部的陆架锋进行了一次专门调査(赵保仁等,1991)。此外,他还指出黄海的强温跃层的形成和转移现象也与潮混合现象密切相关(赵保仁,1989)。因此,研究潮混合现象对阐明发生在黄海的多水文物理现象都是至关重要的。
为深入了解黄海的潮混合特征,作者把渤海、黄海和东海作为一个整体完成了一次精度较高的潮汐、溯流数值计算,在潮汐、潮流的分布方面,揭示了前人尚未阐明的一些特征。本文根据这些数值结果,计算了近最大潮流流速和层化参数,阐明了渤海、黄海和东海的潮混合特征及其对降温期黄海冷水团分布变化的影响。此外,还用 Sim pson等人(1981)的能量模式计算了南黄海西部的风、潮混合效率。

| Abstract: | With the results of numerical modelling of the tide and tidal current this paper discusses the characteristics of tidal mixing in the Bohai Sea, the Yellow Sea and the East China Sea which shows that in the area with significant diurnal tidal current the Simpson-Hunter stratification parameter K, calculated by using quasi-maximum current speed rather than amplitude of M2 constituent tidal current can represent better the characteristics of tidal mixing. Analysis of the relation of the distributions of the bottom cold water (Yellow Sea Cold Water Mass) in the cooling season with tidal mixing showed that the bottom cold water can exlst longer in the northern and southern weak tidal mixing sreas of the Yellow Sea than other areas because of minimum tidal stirring there. The efficiency of wind and tidal mixing in the western part of southern Yellow Sea are also discussed. |
