Spatial and temporal dynamics of aufeis in the Tso Moriri basin, eastern Ladakh, India
Permafrost and Periglacial Processes, Volume 34, Issue 1, Page 81-93, January/March 2023., 2023 Abstract Aufeis is a common phenomenon in cold regions of the Northern Hemisphere that develops during winter by successive water overflow and freezing on ice‐covered surfaces. Most studies on aufeis occurrence focus on regions in North America and Siberia, while research in High Mountain Asia (HMA) is still in an exploratory phase.
