黄海冬季环流的数值模拟

在北黄海和渤海冬季环数值研究的基础上，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了数值模拟。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，数据模拟结果与由资料所分析的结果几乎完全相同。

NUMERICAL SIMULATION OF THE YELLOW SEA l WINTERTIME CIRCULATION

Data of the wintehan drculahon of the Northern Yellow Sea and the BohaiSea (Miao et al.,1988, 1989) were utal for numerical simulahon for the whole YellowSea using boroved numerml dihan Ce Scheme. The comPutahonal results showed that the dibo SCheme completely keeps the conariahons of the mp and volum of themtef in the an areas. Ranrding the Inaor tendency of the circulation, the numerical results ape Well with the analytal results from observahon data. The Yellow Sea circulationSystem mainly consists of the Yellow sa Warm Current flowing northwaul along the Yellow An Trough, the Westean Coastal Current and the Yellow Sea Coastal Current flowing southward along the east ffo and ds coasts of the Yellow Sea,respectively. The Yellow Sea Warm Current and its extension form anticyclonic and a cyclonic circulations respectively with eastern and Westem coastal currents.
