Abstract

Abstract The Yarlung Zsangbo Grand Canyon (YGC) is an important pathway for water vapor transport from southern Asia to the Tibetan Plateau (TP). This area exhibits one of the highest frequencies of convective activity in China, and precipitation often induces natural disasters in local communities, which can dramatically affect their livelihoods. In addition, the produced precipitation gives rise to vast glaciers and large rivers around the YGC. In 2018, the Second Tibetan Plateau Scientific Expedition and Research Program tasked a research team to conduct an “investigation of the precipitation process in the water vapor channel of the Yarlung Zsangbo Grand Canyon (INVC)” in the southeastern TP. This team subsequently established a comprehensive observation system of land-air interaction, water vapor, clouds, and rainfall activity in the YGC. This paper introduces the developed observation system and summarizes the preliminary results obtained during the first two years of the project. Using this INVC observation network, herein, we focus on the development of rainfall events on the southeastern TP. This project also helps to monitor geohazards in the key area of the Sichuan- Tibet railway, which traverses the northern YGC. The observation datasets will benefit future research on mountain meteorology.
雅鲁藏布大峡谷水汽通道降水过程研究
摘要 雅鲁藏布大峡谷是水汽从亚洲南部向青藏高原输送的重要通道。该地区是中国对流活动最频繁的地区之一,降水经常引发自然灾害,严重影响当地居民的生活。此外,产生的降水还在青藏高原周围形成了巨大的冰川和大江大河。2018 年,"第二次青藏高原科学考察与研究计划 "责成研究团队在青藏高原东南部开展 "雅鲁藏布大峡谷(INVC)水汽通道降水过程调查"。随后,该研究小组建立了雅鲁藏布大峡谷陆气相互作用、水汽、云和降雨活动的综合观测系统。本文介绍了所开发的观测系统,并总结了项目头两年取得的初步成果。利用该 INVC 观测网络,我们在本文中重点介绍了东南大陆架降雨事件的发展情况。该项目还有助于监测穿越青藏铁路北部的川藏铁路关键地区的地质灾害。观测数据集将有益于未来的山区气象学研究。
