卫星遥感视角下青藏高原低涡研究进展及展望

Research Progress and Future Prospects in Tibetan Plateau Low Vortex from the Perspective of Satellite Remote Sensing

  • 摘要: 高原低涡是青藏高原重要的天气系统,可造成高原及其周边出现灾害天气,是高原气象研究的重要内容之一。由于青藏高原地形地势复杂,高原低涡在复杂地形及相关大气水汽、感热和潜热等影响下,其移动路径、强度演变、云系和降水等都呈现特有的规律。青藏高原地基气象观测数据相比其他区域稀少并且分布极不均匀,卫星遥感具有全区域覆盖的优势。文中回顾了卫星遥感视角下青藏高原低涡研究进展,主要包括两部分内容:1)卫星遥感高原低涡监测及活动特征研究,包括高原低涡识别、气候特征、云系结构和卫星遥感定量化产品应用;2)卫星遥感高原低涡灾害天气研究,包括高原低涡伴随的对流、暴雨和暴雪灾害天气。最后进行了总结与展望,讨论了风云气象卫星观测数据在高原低涡监测、预警、结构演变等方向的应用前景。

     

    Abstract: The Tibetan Plateau low Vortex (TPV) is a crucial weather system that can trigger hazardous weather both over the Tibetan Plateau (TP) and its surrounding regions, making it an important topic of plateau meteorology research. Owing to the TP's intricate topography and the combined influences of related atmospheric water vapor, sensible heat, and latent heat, etc., the TPV's track, intensity evolution, cloud systems, and precipitation exhibit distinctive patterns. Ground-based meteorological observations over the TP are sparse and extremely uneven compared with other regions, whereas satellite remote sensing offers complete spatial coverage. The article reviews progress in TPV studies from the perspective of satellite remote sensing, focusing on two main aspects: 1) Satellite-based monitoring and activity characteristics research of TPV, including its identification, climatology, cloud-structure analysis, and application of quantitative satellite products; and 2) satellite-based research on TPV-induced severe weather, including accompanying convection, rainstorms, and snowstorms. A summary and outlook are proposed, discussing the prospects of applying FengYun meteorological satellite data in the TPV monitoring, early warning, and structural evolution.
