Effect of dust event timing on glacier runoff: sensitivity analysis for a Tibetan glacier
Abstract
The impact of the timing of dust deposition on glacier runoff was evaluated using a glacier mass-balance model with a newly improved scheme to track a dusted layer in a snow layer of a glacier. The lowering of surface albedo due to the dusted layer appearing leads to a drastic increase of glacier runoff even under the same meteorological conditions. Calculations of seasonal sensitivity, the relationship between dusted date and resulting runoff, have shown that dust deposition during a melting season might cause a drastic mass outflow from a glacier through changing the surface albedo during the melting season.
