摘要
利用RegCM3模式对青藏高原1991—2000年10年夏季（6～8月）的地面气温和降水进行了模拟,其模拟结果与CRU资料的对比分析表明：RegCM3模式的模拟能再现高原地面气温和降水的基本特征,特别是气温,能捕捉到高原北部夏季升温明显高于南部,东北部升温最大;在夏季3个月中,模拟结果和CRU在6月份最为吻合,7月份两者均为夏季气温最高月份和升温幅度最大月份,8月份两者相差较大。RegCM3模式能够模拟出高原降水分布的基本特征和主要干湿中心,由于高原降水的复杂性和模式对降水描述能力的不足,降水模拟要差于气温。
The summer （ June, July and August）air temperature and precipitation over the Tibetan Plateau from 1991 to 2000 have been simulated and studied by using the RegCM3 and ECMWF/ERA40 reanalysis data. After comparing the simulated results with CRU and other related research, RegCM3 show the basic information of air temperature and precipitation over the Tibetan Plateau. This is especially true for the air temperature, not only the reasonable distribution can been acquired, but the variation during the past 10-year summer is captured. RegCM3 successfully simulated the basic precipitation and drought centers, but, because of the complexity of precipitation over the Tibetan Plateau and model＇s limited ability of describing precipitation, the simulated precipitation isn＇t as good as air temperature.
