中文摘要: 通过多种方法对不同分辨率中期数值模式客观分析结果进行诊断分析，考查国家气象中心不同版本模式分析同国际优质版本在分析质量上存在的差异。结果表明，国家气象中心中期数值模式客观分析结果同ECMWF优质版本相比，差异显著地域为：高纬度近极区、我国青藏高原大地形区和太平洋地区。另外，由于模式分辨率的提高，升级版本T106模式比T63模式客观分析质量有明显改进。

Abstract:A major motivation is to diagnose the objective analysis results of different resolution numerical models through some methods and to compare the qualitative difference of the model analysis in NMC. The results show that it is obviously different that the analysis results of the medium-range numerical model in NMC have been carefully compared with that of ECMWF. The regions of the more obvious difference are near the Poles,the QinghaiXizang-Plateau in China and the Pacific Ocean area. On the other hand,the comparison of the objective analysis results between T106 and T63 model indicates that T106 is better than T63 for higher resolution.
