| 摘 要： | 在第一部分提出的陆面过程模式与区域气候模式ＲｅｇＣＭ实现耦合的基础上，利用这一耦合模式（简称ＣＲｅｇＣＭ）对中国中东部地区１９９１年５～７月江淮大暴雨时期的强降水气候特征进行了模拟，并与ＮＣＡＲ的区域气候模式ＲｅｇＣＭ２（此处称ＮＲｅｇＣＭ）在同样初、边值条件和同样物理过程选项下的模拟结果进行了对比分析。分析结果表明，模式ＣＲｅｇＣＭ具有较强的模拟性能和模拟能力，基本上成功地模拟了这次极端的降水气候事件。在某些方面，如地面气温和与陆面过程有关要素的模拟上，ＣＲｅｇＣＭ的模拟结果要比ＮＲｅｇＣＭ的结果更合理。

| Abstract: | The Land-surface Process Model LPM-ZD has been successfully coupled with the regional climate model RegCM2 of NCA R.Then the new coupled model (CRegCM) has been applied to simulate the climate charact eristic of heavy rainfall in middle and east China for three months from May to July 1991,and compared with model output of NCAR-RegCM2 using BATS as land-surface process scheme,abbreviated NRegCM.The results show that CRegCM has good ability and performance.CRegCM successfully simulate the extreme precipitation event and the simulation of CRegCM for surface temperature and some physical variables related to land surface process are more reasonable than those of NRegCM. |
