Numerical Simulation of Large-Scale Circulation in the Pacific Ocean II: Annual Mean Circulation
太平洋大尺度环流数值模拟 II:长期平均环流

The annual mean oceanic general circulation in the Pacific has been simulated by using the four-layer Pacific ocean general circulation model which was described in Part I of this study. Comparing with some available observational data the model proves to be capable of reproducing many of the large scale features of the Pacific circulation including the higher sea level regions in the Western Pacific; Surface current systems and the corresponding gyral structures; the tropical undercurrent and the equatoriward convergence in the subsurface layer; the stronger and narrower upwelling region in the Eastern Equatorial Pacific; the surface layer temperature distribution especially the warm water pool in the Western Pacific, and so on .In addition, the barotropic and baroclinic components of the perturbed pressure and the heat flux at the sea surface are computed and analysed, and some interpretations are given.
