Based on the oceanic CCM with standard stratification subtraction but without the rigid-lid approximation designed in Institute of Atmospheric Physics (IAP OGCM) and its numerical modelings for the large-scale ocean circulation, a numerical model for the Pacific Ocean is developed with higher resolution (2.5°×2° in the longitude and latitude, 8 layers in the vertical),the realistic coastline geometry,the smoothed bottom topography and the Richardson number dependent vertical mixing parameterization.The splitting time integration scheme of the barotropic and baroclinic modes is adopted in the model. The numerical simulation under the annual mean atmospheric forcing shows that the model performance is improved substantially compared with the previous low resolution version.This free surface model,in particular, successfully simulates the well-known ridge-trough structure in the sea level, i.e. the equatorial trough, the equatorial ridge near 3°N, the north countercurrent trough between 8°N and 10°N,
