Simulation of Summer Air Temperature and Precipitation over Tibetan Plateau with Regional Climate Model(RegCM3)

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.
