本文基于FOM(Princeton Ocean Model)建立起日本海环流的数值模式。通过几个在有入(出)流情况下的正压变水深数值实验,检验了地形对日本海环流的影响。结果表明地形是控制日本海环流的重要因子。对马暖流在日本近岸的分支较多地受到地形的影响,这与前人的结论相一致。本文的研究发现在真实地形下,东韩暖流在正压情况下却很难由行星β效应维持。因此,层化效应是形成东韩暖流的必要因素。
Based on the FOM (Princeton Ocean Model), this paper establishes the numerical model of the sea circulation in Japan. The effect of topography on the circulation over the sea of Japan was examined through several numerical experiments of positive pressure and water depth with or without in-flow. The results show that topography is an important factor in controlling the sea circulation in Japan. The impact of the warmth on the coast of Japan in the coastal areas of the country is more affected by the terrain, which is consistent with the conclusions of the predecessors. In this paper, we find that under the real terrain, the warm current of East Korea and South Korea can hardly be maintained by planet β under positive pressure. Therefore, stratification is a necessary factor for the formation of warm currents in East and South Korea.
