摘　　要：利用文献[1]建立的全球海气耦合模式系统(MM/COAMS),对模式的年际变化模拟能力进行了检验.50 a积分显示,模式模拟出了大气和海洋界面的主要年际变率,能真实地模拟热带太平洋ENSO循环的主要特征,较好地再现了ENSO循环的过程,循环周期在3～5 a之间,与实际观测值一致,同时模式也较好地反映了大气和海洋的耦合特征,对年际变化有较强的模拟能力,这与FRAC耦合方案设计有关,该方法能避免气候场的牵制作用,增强模式对年际变化的模拟能力.Based on the Nanjing Institute of Meteorology/Coupled Ocean-Atmosphere Model System （NIM/COAMS） ,the capability of the model in simulating inter-annual variations is verified in this paper. The 50-year integration shows that the model can simulate the main annual variation of the interface between atmosphere and ocean, and the main character and evolution of the ENSO cycle with a period range of 3-5 years in tropic Pacific. The simulation has demonstrated that the model has the capability for simulating the annual variation and air-sea coupling characteristics. These abilities come from the coupled scheme named flux reanalysis coupling scheme （FRAC） which is able to avoid the influence of climatic mean fields, thus enhancing the simulating ability of the annual variation of the model.
