Abstract

A dynamical downscaling is performed to improve the regional climate simulation in China It consists of using a variable resolution model LMDZ4 nested into three global climate models GCMs BCCcsm11m FGOALSg2 and IPSLCM5AMR respectively The regional climate from different simulations is assessed in terms of surface air temperature and rainfalls through a comparison to observations both station data and gridded data The comparison includes climatic trends during the last 40 years statistical distribution of subregional climate and the seasonal cycle For surface air temperature a significant part of the improvement provided by LMDZ4 is related to the effect of surface elevation which is more realistic in highresolution simulations the rest is related to changes in regional or local atmospheric general circulation All GCMs and the downscaling model LMDZ4 are more or less able to describe the spatial distribution of surface air temperature and precipitation in China LMDZ4 does show its superiority compared to GCMs in depicting a good regional terrain including the Tibetan Plateau the Sichuan Basin and the Qilian MountainsThis work is supported jointly by the National Natural Science Foundation of China Grant No 41230528 National Program on Key Basic Research Project of China Grant No 2012CB955204 China RD Special Fund for Public Welfare Industry meteorology GYHY201306024 and a Project Funded by the Priority Academic Program Development PAPD of Jiangsu Higher Education Institutions Helpful comments from the anonymous reviewers are greatly appreciated
