摘要
利用一个耦合的数值模式对南海东北部及台湾海峡附近的环流进行数值模拟,以研究多种可能的动力机制对该海区的影响。结果表明:当以风应力、黑潮作为驱动机制时,该模式的计算结果大致与正压模式的计算结果相同;风应力促使研究海区流场的结构和强度发生变化,而黑潮才可能是该海区动力机制的主要因子。黑潮人流、入射角及海区层结程度等因素对该海区流态变化的影响较大;文章同时指出摩擦效应对于流场结构产生影响的重要性。
In order to study the effect of multi-likelihood of dynamic mechanism in the northeastern South China Sea (SCS), Taiwan Strait and its adjacent waters, in couple model is used to simulate the circulation in the above sea areas. It is shown that when wind stress and Kuroshio are given as dirving mechanism, the model's computational results are almost the same as those of barostropic model. Wind stress brings about intensity and structure changes of current field in the above sea areas,while Kuroshio may be a main factor after all. The inflow transport, incident angle of Kuroshio and the stratification extent of the sea areas can affect the flow state in the stUdied areas greatly. The importance of frictional effect on the current field structure is also shown in the paper.
