To study the effects of the uplift of Qinghai-Xizang Plateau(QXP) on Asian atmospheric general circulation in spring and summer,the experiments with and without QXP are performed respectively(called TP-Experiment and NTP-Experiment hereafter) for 10 years using an atmospheric general circulation model with rhomboidal truncation(R42L9).Comparing the results of TP Experiment with NTP-Experiment,it is showed that the Asian atmospheric general circulation has a strong response to the uplift of QXP.The QXP split the westerlies and force them to flow around it in lower level.There are two branches of the westerlies,one flow to the north and the other to the south of the Plateau.The northern branch strengthen cold air go down southward to Eastern Asia.The intensity of southern branch enhances because of weaken heating of the QXP in spring.The enhanced southern branch transport moisture to southern China.Meeting of cold and warm air in southern China causes heavy rain in there in spring.In summer,cyclonic circulation caused by the QXP strong heating source in lower level enhances the Eastern Asia summer monsoon on the east side of QXP and make it develop northward.However,the sensible heat air pumping of QXP bring negative vorticity and divergence over southern Asia in lowew level,and decrease the precipitation in there in summer.So the southern Asia summer monsoon weakens with the uplift of QXP.Another thermal influence of the QXP is reflected in upper level.The negative vorticity sources over the Plateau generated by the QXP heating strengthen the Iran high at 200 hPa in a remote way.
