Abstract

The change of north edge of the Asian summer monsoon under the global warming is investigated using the NCAR CAM3 global atmospheric circulation model through numerical experiment of doubled CO2. The overall large-scale features of the eastern Asian monsoon are captured rather well by the Control_run and doubled CO2experiment. In doubled CO2 concentration experiment, the north edge is more northward, which indicates a stronger monsoon. The analysis demonstrates that the surfacetemperature increasing from enhancedradiative force makes the cyclonic circulation in the lower level of Qinghai-Xizang Plateau stronger, which furtherstrengthens the zonal thermal contrast between sea and land; moreover the moisturecontent is remarkably increased in the North  China. Furthermore, it is shown that the thermal difference between the Northern and Southern Hemispheres hardly changes comparing with the Control_run. Those imply that theinteraction of bothHemisphereshas a relativelysmall impact onthe intensification of the Asian summer monsoonactivity.
