黄海冬季环流的数值模拟
刘兴泉
中国科学院海洋研究所 青岛 266071
摘要:
在北黄海和渤海冬季环流数值研究的基础上，利用其进一步改进的数值差分格式，对整个黄海的冬季环流进行数值模拟。数模结果表明，改进的差分格式完全保持了计算海区的总能量和总质量守恒。就环流的总趋势而论，数值模拟结果与由观测资料所分析的结果几乎完全相同。黄海的环流系统主要由以下环流构成：沿黄海槽北上的黄海暖流及其余脉，分别沿东西两岸南下的西朝鲜沿岸流和黄海沿岸流，黄海暖流及其余脉分别与东西沿岸流之间形成的反气旋和气旋环流。

NUMERICAL SIMULATION OF THE YELLOW SEA l WINTERTIME CIRCULATION

Abstract:
Data of the wintertime circulation of the Northern Yellow Sea and the Bohai Sea (Miao et al., 1988, 1989) were used for numerical simulation for the whole Yellow Sea using improved numerical difference scheme. The computational results showed that the difference scheme completely keeps the conservations of the energy and volume of the seawater in the sea areas. Recording the major tendency of the circulation. the numerical results agree well with the analysed results from observation data. The Yellow Sea circulation system mainly consists of the Yellow Sea Warm Current flowing northward along the Yellow Sea Trough, the Western Korean Coastal Current and the Yellow Sea Coastal Current flowing southward along the eastern and western coasts of the Yellow Sea, respectively. The Yellow Sea Warm Current and its extension form anticyclonic and a cyclonic circulations respectively with eastern and western coastal currents.
Key words:  Yellow Sea, Circulation, Energy mass concervations, Cyclonic and anticyclonic circulations
