Circumpolar and high-elevation cold regions receive a large portion of their annual precipitation as snowfall, which accumulates in snowpacks that can store many contaminants. The discharge of chemical eluent during snowmelt can alter the chemical composition of local streams and have a detrimental effect on aquatic ecosystems.

通过改进分层雪和雨雪 （ROS） 事件中液态水运动的表示来改进积雪化学模拟：在挪威斯瓦尔巴群岛的应用


极地和高海拔寒冷地区每年降水的很大一部分是降雪，降雪积聚在积雪中，可以储存许多污染物。融雪过程中化学洗脱液的排放会改变当地溪流的化学成分，并对水生生态系统产生不利影响。
