Short summary
Based on observations and trajectory model, we show that the geographic variation of dehydration center associated with that of convection has a significant influence on locations where air mass is dehydrated, and thus water vapor enters the lower stratosphere, in summer over the Asian monsoon region. Specifically, a westward shift of dehydration center toward the area of warmer tropopause temperatures tends to moisten the lower stratosphere.
