主 题：Mid-summer SAT Internal variability China 1.5℃global warming 2℃global warming
摘 要：Recently,extremely hot summers occurred frequently across China,and the mean mid-summer surface air temperature(SAT)continuously broke the records of the past decades,causing huge social and economic *** global warming accelerates,these extremely hot summers will undoubtedly occur more ***,the issue of what will happen to the mid-summer SAT over China in the near future remains ***,we investigate the changes of mid-summer SAT and related internal variabilities over China at 1.5℃ and 2℃ global warming above preindustrial level by using the MPI-ESM Grand Ensemble *** results indicate that compared to the present-day(1986–2005),national averaged mid-summer SAT will increase by 1.1℃ and 2.0℃,in 1.5℃ and 2℃ warming scenarios *** means that the mid-summer SAT is projected to increase by 0.9℃ due to an additional 0.5℃ global warming,which is higher than the annual value(0.8℃)and almost two times the global warming ***,in the two warming targets,the increase in mid-summer SAT will be more enhanced over the northwestern part of *** addition,the extremely high monthly SAT would increase nationwide due to an additional 0.5℃ in global *** all areas,the Qinghai and Xinjiang provinces would experience the strongest increase in extremely high monthly *** is important to find that,from 1.5℃ to 2℃ global warming,changes of the internal variability of the mid-summer SAT differs across *** would decrease over some parts of western Northwest China,North China,Northeast China and the Tibetan ***,it would significantly increase over Qinghai,Sichuan,and northern parts of Inner *** a result,at 2℃ global warming,the increase of extreme SAT in Qinghai is caused by the synergistic effect of stronger warming rate and larger internal ***,the increase in Xinjiang province is mainly caused by the stronger local *** analysis suggests that we can effect
