基于曾庆存海洋环流模式设计思想和大气物理研究所海洋环流模式(IAPOGCM),设计并实现了高分辨率的自由表面热带太平洋环流模式(区域为南北纬30°,经纬圈方向的水平分辨率分别为1°和2°,垂直方向分为14层).模式中考虑了盐度并引入与洋流切变和层结稳定度有关的垂直扩散参数化方案及对流调整方案.用该模式已进行了大量的数值模拟和比较试验,充分表明该模式的优良性能和广阔的应用前景.文中给出了一些热带太平洋环流数值模拟及其应用实例.
Based on Zeng Qing-huang’s theory of ocean circulation model and IAPOGCM, a high-resolution free-surface tropical Pacific circulation model is designed and implemented (the region is latitude 30 ° north-south, the horizontal resolution in the latitude and longitude direction is 1 ° and 2 ° in the vertical direction and 14 layers in the vertical direction), salinity is taken into account in the model and the vertical diffusion parameterization scheme and convection adjustment scheme are introduced in relation to the ocean current shear and the stability of the strata. Numerical simulation and comparative experiments, which fully demonstrate the excellent performance and broad application prospects of the model.There are some numerical examples of tropical Pacific circulation and its application examples.
