摘要
本文利用POM模式对环台湾岛海域冬季的水文要素进行了数值模拟,对有代表性的水平环流、温度场和上升流三个要素所进行的分析表明:模式再现了台湾岛东岸的高温高盐强流速区即黑潮,黑潮在冬季并无直接进入台湾海峡的分支存在;西岸的东北向流在冬季各个层次上都存在,台湾东北部的冷涡模拟与实况较为一致。温度场和上升流的分布与水平环流有很好的对应关系。本文还进一步验证了前人的一些研究成果,并对一些特殊物理现象的成因进行了定性解释。
In this paper, the numerical simulation of hydrographic characteristics in the sea area around Taiwan Island in winter is conducted by use of POM. The analysis to the representative horizontal circulation, temperature distribution and upwelling show that the model can reproduce the Kuroshio, the stronger current with higher temperature and denser salinity near east coast of Taiwan Island, and there is no separated branch of Kuroshio entering Taiwan Strait in winter. The northeast ward flow near west coast appears from surface to the bottom all the time in winter, and the simulated cold eddy northeast to Taiwan is agreeable with observation. Meanwhile, the temperature and the upwelling is consistence with horizontal current. Based on the further verification to the former results, the possible mechanism of some specific phenomena is also explained.
