本文基于大气物理研究所海洋环流模式和太平洋大尺度环流数值模拟工作,设计了一个考虑实际海陆分布和海底地形、较高分辨率的太平洋环流数值模式(水平经纬圈方向网格距为2°×2.5°,垂直方向为不等距的8层);并且采用垂直扩散参数化方法和稳定有效的时间积分方案.在年平均大气强迫场驱动下成功地模拟出海面起伏中赤道槽、赤道脊、北赤道逆流槽和北赤道脊等分布特征;完整地模拟出与这些槽脊分布相对应的北赤道洋流、南赤道洋流和介于它们两者之间的北赤道逆流;模拟得到的黑潮和赤道潜流强度也和观测结果相当.
Based on the ocean circulation model of the Institute of Atmospheric Physics and numerical simulation of the large-scale circulation in the Pacific Ocean, a numerical model of the Pacific Ocean circulation considering the actual sea-land distribution and the seafloor topography and high resolution is designed (the grid spacing in the horizontal latitude and longitude is 2 ° × 2.5 °, vertical direction is not equal to the 8th floor); and using vertical diffusion parameterization method and stable and effective time integral scheme.Under the condition of annual mean atmospheric forcing field, the equatorial groove, equator ridge, North Equatorial Countercurrent Channel and the Northern Equator Ridge. The North Equatorial Current, the South Equatorial Current and the North Equatorial Current between them are completely simulated. The simulated Kuroshio Current The equatorial underflow intensity is also comparable to the observations.
