摘　　要：应用AMIP- II计划提供的 1 979～ 1 996年海温及海冰场作下边界条件运行国家气候中心的大气环流模式 ,将模式的输出结果与NCEP资料进行对比以便验证模式模拟实际大气运动变化的能力。验证的结果表明 :国家气候中心的大气环流模式能够模拟出对流层大气的大尺度运动特征 ,如高度场、温度场及风场的特征等 ,但对降水的模拟则有较大的误差 ;此外模式对对流层上层及平流层温度等要素的模拟也存在着较大的误差 ;模式的物理过程也需要进一步进行改进。The 1979-1996 SST and sea ice data provided by AMIP-II project was used as lower boundary condition to run the National Climate Center's (NCC) AGCM for 16 years. The model output was compared to the NCEP reanalysis data set in order to validate the abilities of the model in simulating the motion and variation of the real atmosphere. The verification results show that the NCC AGCM can pretty well simulate the large scale characteristics of the atmosphere such as the temperature, the geopotential height, the wind field and so on. The simulation of the precipitation has relatively large error. There are also some large errors in the simulation to the temperature in upper troposphere and stratosphere. The model physics also need to be improved.
