The Qinling-Bashan Mountains (QBMs) serve as an important boundary between southern and northern China and are dubbed China’s Central Water Tower (CCWT). However, the spatiotemporal structures and dynamics of the summer hydroclimate, as well as the water vapor sources and mechanisms in this CCWT during the peak and most concentrated precipitation period, which is crucial for forest growth, crop yield, and water management, remain unclear.
