利用冰川质量平衡模型和一个新的改进方案，对冰川雪层中的粉尘层进行跟踪，评估了粉尘沉积时间对冰川径流的影响。在相同的气象条件下，由于粉尘层的出现，地表径流量降低，导致冰川径流量急剧增加。对季节敏感性的计算，即灰尘日期与由此产生的径流之间的关系，表明在融化季节灰尘沉积可能会通过改变融化季节的表面湿度而导致冰川的大量外流。版权所有（c）2006约翰威利父子有限公司。
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.
