摘要
为了检验高分辨率区域气候模式RegCM3对新疆气候的模拟能力,对2005年夏季气候进行了模拟试验,针对模拟的温度场和降水场作了具体分析,并利用新疆境内102个气象站点的逐日资料对温度场和降水场进行了检验分析。温度场的模拟结果表明,模式能较好地反映新疆的温度场空间分布特征,但在数值上出现明显的"冷偏差",整体偏低4～7℃;模式较好地模拟了新疆的夏季降水特征:降水高值区位于天山山区。模式对平原地区的降水模拟较接近实测值,但对山区的模拟效果较差。
To verify the simulating ability of RegCM3 in Xingjiang,the climate of summer in 2005 was simulated using this model. Its capability of simulation for temperature and precipitation was investigated.The results showed that RegCM3 model has ability to simulate the basic character of the spatial distribution of precipitation and temperature over Xingjiang. Regional-averaged air temperature had the cold bias of 4-7 ℃. Simulated ability to precipitation indicated that the method was effective in plain areas,while not so good in mountain areas.
