| 摘 要： | 利用区域气候模式RegCM3对1991-2004年四川盆地夏季降水进行了数值模拟,通过模拟结果和NCEP/NCAR再分析资料的对比,评估了模式对四川盆地夏季＂夜雨＂现象的模拟能力。结果表明,RegCM3模式能较好地模拟出四川盆地夏季降水的空间分布和日变化规律,四川盆地夏季＂夜雨＂现象的形成与该地区的地形分布有密切关系。...

| Abstract: | A regional climate model(RegCM3) has been applied to simulate the summer precipitation in Sichuan basin during 1991-2004.The station rain-gauge data and NCEP/NCAR reanalysis data are used to evaluate the performance of the model to simulate the diurnal cycle of precipitation,especially the formation of mid-night maximum rainfall.The results show that the RegCM3 can simulate well the spatial distribution and diurnal variation of averaged precipitation in Sichuan basin.The orography forcing is related to the ... |
