Impact of the Western Tibetan Vortex on Springtime Snow Cover Over the Western Tibetan Plateau

Geophysical Research Letters, Volume 52, Issue 14, 28 July 2025.
Abstract Snow cover changes are of great importance to the hydrological cycle of the western Tibetan Plateau (TP). However, the influence of the atmospheric circulation on snow cover over the western TP is still unclear. This study finds that springtime snow cover variability over the western TP tail is significantly modulated by the Western Tibetan ...

High‐Resolution Terrestrial Water Storage Anomalies and Components in China From GRACE/GFO via Joint Inversion Downscaling

Water Resources Research, Volume 61, Issue 7, July 2025.
Abstract Satellite gravimetry (Gravity Recovery and Climate Experiment (GRACE)/GRACE Follow‐On (GFO)) has solved the challenge of monitoring global and basin‐scale terrestrial water storage anomalies (TWSA) at monthly intervals and spatial scales of ∼330 km.

Retrieval of Snow Grain Size over the Tibetan Plateau: Preliminary Cross-Validation Between Optical and Satellite Altimetry Data

Remote Sensing
Snow grain size is important in albedo calculation, mass balance, and climate research. Critically, in situ measurements of snow grain size on the Tibetan Plateau remain scarce.

Rock Glacier Velocity: An Essential Climate Variable Quantity for Permafrost

Reviews of Geophysics, Volume 63, Issue 1, March 2025.
Abstract Rock glaciers are distinctive debris landforms found worldwide in cold mountainous regions. They express the long‐term movement of perennially frozen ground. Rock Glacier Velocity (RGV), defined as the time series of the annualized surface velocity of a rock glacier unit or a part of it, has been accepted as an Essential Climate Variable ...

GRAVITY ANOMALIES OF THE CRUST AND UPPER MANTLE FOR CENTRAL AND SOUTH ASIA

Геодинамика и тектонофизика, 2016
Studying the density of both the crust and mantle is one of the topical problems in modern geophysics. Gravity modeling in combination with seismic tomography is an important tool for detecting density inhomogeneities in the crust and mantle, which can ...

Glacial Grafting and the Karakoram Anomaly: Bridging Indigenous Knowledge and Hydrologic Science for Meltwater Preservation

While glaciers worldwide are retreating due to anthropogenic climate change, the Hunza region of Northern Pakistan presents a striking exception: the Karakoram Anomaly, where glaciers have remained stable or are even advancing (Farinotti et al., 2020). At the same time, communities in the region have practiced glacial grafting for centuries.

Annual and Seasonal Variations in Glacier Velocity, and Surging Glaciers in the West Kunlun Mountain

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Monitoring glacier velocity is crucial for revealing glacier dynamics and clarifying the responses of glaciers to climate change. The West Kunlun mountain (WKM) is at the center of the Karakoram Anomaly; however, insufficient systematic studies have been
