Orographic Effects on Precipitation Microphysics and Vertical Structure over the Sichuan Basin and Its Surrounding Regions Using GPM-DPR Data (2015–2022) Open
Using GPM-DPR observations from 2015 to 2022, this study investigates how two key topographic factors—elevation and slope—shape the vertical structures and microphysical characteristics of stratiform precipitation (SP) and convective preci…

Comparison of a Manual and an Automated Tracking Method for Tibetan Plateau Vortices Open
Tibetan Plateau vortices (TPVs) are mesoscale cyclones originating over the Tibetan Plateau (TP) during the extended summer season (April–September). Most TPVs stay on the TP, but a small number can move off the TP to the east. TPVs are kn…
