中文摘要：

(RIEMS2.0 ) 地区性的综合环境建模系统版本 2.0 现在被地区性的 ClimateEnvironment 的关键实验室为适度的东亚正在开发，中国科学院。为了测试 RIEMS2.0 模型域的敏感模仿长期的气候和它的变化，并且为模型，的进一步的开发和应用程序提供一个基础，作者在不同积云 parameterization 计划下面用二模型域比较了在模仿并且观察的降水和 surfaceairtemperature 之间的结果。模型被 NCEP/NCAR 分析数据驾驶，模拟持续时间从 1979 年 1 月 1 日到 2007 年 12 月 31 日。没有重要差别，在模仿的降水的空间分布发现并且在二个模型领域之间的 surfaceairtemperature，或 interannual 变化。然而，有差别，在本地分区的二模型领域模拟之间观察。更小的模型领域更精确地模仿了降水，特别在夏天(6 月， 7 月，和 8 月) ，并且减少 surfaceairtemperature 的偏爱，特别在冬季(12 月， 1 月，和 2 月) 。更小的模型领域模仿的弱夏天和冬季季风是边界 forcings 的结果并且可以部分说明这个模型的改进。

英文摘要：

Regional Integrated Environment Modeling System Version 2.0 （RIEMS2.0） is now being developed by the Key Laboratory of Regional Climate-Environment for Temperate East Asia, Chinese Academy of Sciences. In order to test the sensitivity of the RIEMS2.0 model domain to simulate long-term climate and its change, and provide a basis for the further development and application of the model, the authors compared results between simulated and observed precipitation and surface-airtemperature using two model domains under different cumulus parameterization schemes. The model was driven by NCEP/NCAR re-analysis data with a simulation duration ranging from 1 January 1979 to 31 December 2007. There were no significant differences found in the spatial distributions of the simulated precipitation and surface-air-temperature, or interannual variations between the two model domains. There were, however, differences observed between the two model domain simulations of local sub-regions. The smaller model domain more accurately simulated precipitation, especially in summer （June, July, and August）, and decreased the bias of surface-airtemperature, especially in winter （December, January, and February）. The weak summer and winter monsoons simulated by the smaller model domain was a result of boundary forcings and may partially account for the improvements of this model.
