摘要 Consideringtheimportanceofblackcarbon(BC),thisstudybeganbycomparingthe20thcenturysimulationofSouthAsiansummerclimateinIPCCCMIP3,basedonthescenarioofmodelswithandwithoutBC.Generally,themulti-modelmeanofthemodelsthatincludeBCreproducedtheobservedclimaterelativelybetterthanthosethatdidnot.Then,the21stcenturySouthAsiansummerprecipitationwasprojectedbasedontheIPCCCMIP3projectionsimulations.Theprojectedprecipitationinthepresentapproachexhibitedaconsiderabledifferencefromthemultimodelensemblemean(MME)ofIPCCAR4projectionsimulations,andalsofromtheMMEofthemodelsthatignoretheeffectofBC.Inparticular,thepresentprojectionexhibitedadryanomalyoverthecentralIndianPeninsula,sandwichedbetweenwetconditionsonthesouthernandnorthernsidesofPakistanandIndia,ratherthanhomogeneouswetconditionsasseenintheMMEofIPCCAR4.Thus,thespatialpatternofSouthAsiansummerrainfallinthefuturemaybemorecomplicatedthanpreviouslythought.
