Abstract. By using the multi-source data of meteorology over recent decades, this study discovered a summertime “hollow wet pool” in the troposphere with a center of high water vapor over Asian water tower (AWT) on the Tibetan Plateau (TP), where is featured by a vertical transport “window” in the troposphere. The water vapor transport in the upper troposphere extends from the vertical transport window over the TP with the significant connections among the Arctic, Antarctic and TP regions, highlighting an effect of TP’s vertical transport window of tropospheric vapor in the “hollow wet pool” on global change. The vertical transport window was built by the AWT’s thermal forcing in associated with the dynamic effect of the TP’s “hollow heat island”. Our study improve the understanding on the vapor transport over the TP with an important implication to global change.

Short summary
A vertical transport window of tropospheric vapor exists on the Tibetan Plateau (TP). TP’s thermal forcing drives the vertical transport “window” of vapor in the troposphere. Effects of TP’s vertical transport “window” of vapor is of importance on global change.
