Abstract:Using the station data in Hebei area,a test analysis is maded on simulated results from China climate change projection data provided by National Climate Center.Results show that:1)July precipitation simulated by the regional model(RegMV) exists systematic deviation,which is larger in southern Zhangjiakou-Sangyang River basin and northern Zhangjiakou-Dam Plateau,but significantly smaller in Xinglong mountains east to Beijing and southeast coastal areas.2)July maximum temperature simulated by RegMV exists systematic deviation,which is significantly higher in Xinglong mountains east to Beijing and eastern plain region,but lower in southern Zhangjiakou-Sangyang River basin and eastern Taihang Mountains.3)January minimum temperature simulated by RegMV exists systematic deviation,which is higher in Xinglong mountains east to Beijing,North Taihang Mountains,and eastern plain region,but lower in southern Zhangjiakou-Sangyang River basin and eastern Taihang Mountains.4)The global model is difficult to describe terrain features of Hebei due to its low spatial resolution.Whether precipitation or temperature is simulated,the results are poor.The regional climate model has a certain improvement in describing terrain features of Hebei by improving the resolution,so its simulations have been improved significantly.However,due to the limit of the spatial resolution,such local terrain as Xinglong Mountains,Sangyang River basin,northern Taihang Mountains and other terrain are not well characterized,so the simulated results appear systematic deviation in these areas.It needs an improvement for the application of this set of data in Hebei area.
