基于黄、东海Lagrange环流数值模型 ,对黄、东海Lagrange斜压环流进行了诊断计算。采用流速分解法将La grange流速分解为梯度流、风海流、潮致余流、热盐环流、零阶环流耦合流 5种分量 ,实现三维计算的准二维化。计算结果较成功地模拟了冬夏两季黄、东海Lagrange环流 ,表明密度环流在冬、夏季均是东海环流的重要分量 ,可显著增强了东海黑潮、东海黑潮、台湾暖流和对马暖流 ;在夏季还是黄海环流的主要分量。
Based on the Lagrange circulation numerical model of the Yellow Sea and the East China Sea, the Lagrange pressure circulation in the Yellow Sea and the East China Sea was diagnosed and calculated. The flow rate decomposition method is used to decompose La grange flow into five kinds of components: gradient flow, wind current, tide-induced residual flow, hot salt circulation and zero-order circulation coupled flow. The results show that the Lagrange circulation in the Yellow Sea and the East China Sea is simulated successfully in both winter and summer, indicating that the density circulation is an important component of the circulation over the East China Sea in winter and summer. It can significantly enhance the Kuroshio in the East China Sea, the Kuroshio in the East China Sea, In the summer or the Yellow Sea circulation is the main component.
