| 摘 要： | 使用RegCM3区域气候模式，利用ECMWF的ERA40再分析资料，对东亚地区进行了长达15年（1987-2001年）时间的数值积分试验，重点分析了模式对青藏高原及青藏铁路沿线地区气温和降水的模拟。结果表明，RegCM3模式具有模拟青藏高原及周边地区当代降水和气温主要分布特征的能力，尤其在观测站点稀少地区可提供局地降水和气温分布的较可靠信息。模式较好地模拟了青藏铁路沿线地区的降水，特别是气温的年变化趋势，同时也较好地模拟了这一地区气温的年际变化，但对该区降水年际变化的模拟能力则有待进一步提高。 |

| Abstract: | The simulation of climate in East Asia region in 15 years were carried out by the RegCM3 nested into ERA40 re-analysis data. The simulation of the temperature and precipitation distribution and changes over Qinghai-Xizang Plateau and along the Qinghai-Xizang Railway were mainly investigated. The results show that RegCM3 model has ability to simulate the basic character of the spatial distribution of precipitation and temperature over Qinghai-Xizang Plateau and along the railway region. At same time, the model simulation can provid more reliable information of local precipitation and air temperature for the region of rare observation station. The model can reproduce well the precipitation along Qinghai-Xizang railway, especially the change trend of air temperature in each month of a year. The annual change of air temperature in the region is well simulated, but the simulated ability to the annual change of precipitation in this region remain to be improved. |
