The results show that the RIEMS can simulate the pattem and seasonal cycle of standard deviation of surface temperature and precipitation.

第一部分是检验RIEMS模式对东亚地区十年平均气候状况的模拟能力，结果表明，RIEMS模式能够较好地模拟出不同季节温度(包括平均温度、最高温度、最低温度)的空间分布和季节变化以及不同区域温度的年变化；无论是平均温度，还是最高温度、最低温度，模式模拟季平均和月平均温度与观测之间偏差大约一般在1-2℃，这与IPCC(2001)报告中报告的在区域尺度10〓-10〓KM，季平均温度偏差在1-2℃较为一致；模式能够较好地模拟降水的空间分布特征和季节变化以及不同区域平均降水的年变化，同时，也能够较好地模拟出雨带季节性的演变，但模拟的雨带位置较观测偏北，大约为2-3纬度；就季节而言，模式模拟最好的季节为冬季，较差的季节为夏季；模式基本上能够较好的模拟出不同季节平均海平面气压场的空间分布以及东亚地区的湿润和干旱分布规律的干旱指数的空间分布。
