Short summary
Short summary
Wind-blown dust lifting mechanisms remain unclear.Using field observations and wind tunnel experiments, we show that aerodynamic entrainment persistently lifts dust, contributing 16–62 % of total emissions. Saltating sand not only splashes dust into the air but also scours the surface, replenishing fine particles. These results challenge current models, and we propose a new framework to better represent these processes, improving dust prediction and supporting environmental.

Short summary
Short summary
As the transition zone between the Tibetan Plateau and the arid region, the Qilian Mountains are important ecological barriers and source regions of inland rivers in northwest China. In recent decades, drastic changes in the cryosphere have had a significant impact on the quantity and formation process of water resources in the Qilian Mountains. The mountain runoff of the Qilian Mountains mainly comes from the cryosphere belt, which contributes to approximately 80 % runoff.

Short summary
Precipitation, ground ice, and snow meltwater accounted for approximately 72 %, 20 %, and 8 % of soil water during the early ablation period. Snow is completely melted in the heavy ablation period and the end of the ablation period, and precipitation contributed about 90 % and 94 % of soil water, respectively. These recharges also vary markedly with altitude and vegetation type.
