为了检验RegCM3区域气候模式对青藏高原地区的模拟能力,利用NCEP再分析资料和观测站点资料,采用三种不同的对流参数化方案,对青藏高原地区2006年夏季进行了模拟分析,并重点对温度和降水进行了细致的检验.结果表明:模式能较好地再现青藏高原地区大尺度的环流特征,具有对青藏高原地区的温度和降水分布特征的模拟能力;对于量值的模拟,三种对流参数化方案均模拟出了与实况温度一致的变化趋势,但均存在5～6 ℃的冷偏差;Grell方案模拟的降水量均大于实况,Kuo-Anthes方案对于高原地区的降水量的模拟较为接近于实况,但模式对降水量的模拟能力仍有待进一步提高.

With the NCEP reanalysis data and the observational data, we present a preliminary evaluation of the performance of three different cumulus parameterization schemes in the ICTP Regional Climate Model RegCM3 over the Qinghai-Xizang Plateau during the summer (June-July-August), especially for temperature and precipitation. The model can well reproduce the large scale circulation characteristics and the distribution of air temperature and precipitation over the Qinghai-Xizang Plateau, but it has some deviations of the value. Three cumulus parameterization schemes can also produce the same change trend of air temperature with the observational data, but they also have cold bias (5-6 ℃). Scheme of Kuo-Anthes has the better performance because Scheme of Grell trends to produce more precipitation, but it's necessary to improve the model's ability of the precipitation simulation.
