英文摘要	Regional climates have changed as a result of global warming, which has sped up cirrus circulation and altered the temporal and spatial distribution of precipitation. As climate change intensifies, the pattern of precipitation in the Hoh Xil (HX) region has changed. The dislocation of rain and heat in summer hinders ecological restoration and brings great ecological threat. And it is important to clarify the causes and scopes of the midsummer drought (MSD). In this study we highlight the causes of MSD in terms of water vapour transport, circulation structure and the related influencing factors. We found that (1) the HX region gradually entered a drying-warming process as MSD developed after 2005. (2) The change in the water vapour balance is the direct cause of MSD in the HX. (3) As a typical climate key zone, the HX is located in the transition region between the westerlies and the Indian monsoon. (4) Regional evaporation capacity is the main factor affecting the occurrence of MSD. The dominant factor shifted from being energy to water with the occurrence and enhancement of MSD. This study complements the scarce research on precipitation anomalies in the HX, provides support for clarifying the impact of climate change on the Qinghai-Tibet Plateau (TP) and contributes to understanding the trends and mechanisms of climate change over the TP under global warming.
