通过一个高分辨(1/6度×1/6度)南海环流模式,在旋转加快(spin-up)过程中分析了南海上层海洋季风驱动下海盆尺度环流特征建立的方式与内在机制,分析了南海自静止态至海盆尺度环流特征初步形成的过程,揭示了此过程中边界截获Kelvin波和西传斜压Rossby波的重要作用,由此估算了南海上层海洋季风性海流调整的特征时间尺度.
Through a high-resolution (1/6 degree × 1/6) South China Sea circulation model, the establishment and internal mechanism of the scale circulation in the basin driven by the monsoon over the South China Sea are analyzed during the spin-up process. The process from the standstill of the South China Sea to the circulation features of the basin scale reveals the important role of the boundary intercept of the Kelvin and the baroclinic Rossby waves in the process, thus estimating the characteristic time scale of the adjustment of the upper ocean monsoon current in the South China Sea.
