Role of blowing snow in snow processes in Qilian Mountainous region
Quantifies sublimation losses from blowing snow in the Qilian Mountains. Blowing-snow sublimation accounted for 41.5% of total snow sublimation at Yakou in 2008, demonstrating its substantial contribution to snow-season water loss.
