摘要

摘要: 用一个三维、自由表面、原始方程模式对南海环流进行了计算.计算结果表明:黑潮在巴士海峡以西呈一反气旋弯曲流动路径,有一相对高温高盐的水舌从巴士海峡伸入南海,表明有部分黑潮水侵入南海.冬季南海的一些观测事实在模式结果里得到了很好的反映,像冬季逆风向东北方向流动的“南海暖流”和一些中尺度涡旋.同时还分析了巴士海峡沿120.75°E断面的流速和盐度的垂直结构,并同观测结果进行了比较.根据模式结果,我们还进一步讨论了“南海暖流”的形成和驱动机制.

Abstract: The wintertime circulation in the South China Sea(SCS) has been simulated by using a three-dimensional,primitive-equation model with a free surface.Computed results show that:a realanticy clonic meandering path of the Kuroshio appears west of the Bashi Channel(BC),and a tongue with relatively high temperature and salinity spreads into SCS from BC which represents a intrusion of the Kuroshio.Some observed discoveries in SCS in winter such as the South China Sea Warm Current(SCSWC) which is against wind flowing northeastward(N E-ward),and some mesoscale eddies are all revealed by the model.The vertical structure of velocity and salinity alog 120.75°E Section in BC reproduced by the model compare well with observations.Based on the model results we also discuss further the formation and driving mechanism of SCSWC.
