影响“亚洲水塔”的水汽输送过程

Water Vapor Transport Processes on Asian Water Tower

青藏高原及其周边区域被誉为“亚洲水塔”,过去50年的全球变暖加速了整个“亚洲水塔”的水循环过程。文章从气候态、长期变化和年际变率的角度,总结了当前对影响“亚洲水塔”的关键水汽输送过程及其机理的理解。在此基础上,指出要厘清影响“亚洲水塔”的水循环过程,亟待深入理解水塔的水汽输送过程的时空变化特征和机制及其影响。为此,需要从观测、诊断、动力学机理、检测归因和数值模拟5个方面加强未来的研究工作。

The Tibetan Plateau is known as the“Asian Water Tower”.In the past 50 years,global warming has accelerated the water cycle over the Asian Water Tower.The current understanding on the key processes of water vapor transport over the Asian Water Tower and the behind mechanisms are reviewed in this paper,via the climatology,long-term trend,and interannual variability,respectively.This review further suggests that it is urgent to understand the tempo-spatial changes,mechanisms,and impact of water vapor transport processes over the Asian Water Tower.Therefore,future research should improve capabilities on observation,diagnosis,dynamical mechanism,detection and attribution,as well as numerical simulation.
