Degree-day factor is an important parameter of degree-day model which is a widely used method for ice and snow melt computation.

在冰川与积雪消融研究中，度日模型应用较为广泛，该模型是基于冰雪消融与气温，尤其是正积温之间的线性关系建立的。

The ice and snow melt of different seasons in high mountains can obviously affect the variation in isotope composition and deuterium excess parameters of surface flow and shallow groundwater.

不同季节高原高山冰雪的溶融，可以明显地影响地表径流和浅层地下水的同位素组成及氘过量参数的变化。

Most of the Arctic is covered in snow and ice, which are highly reflective; if snow and ice melt, the exposed soil, which absorbs heat, serves to accelerate warming.

北极大部分地区被冰雪覆盖，具有很强的反射性；如果冰雪融化，裸露的土壤吸收热量，有助于加速变暖。

But the snow does melt. Ice cold water travels down the mountains and forms several rivers -- the Gila River,the Green River, the Little Colorado,the San Juan, the Virgin and the Gunnison Rivers.

This phenomenon, called Arctic amplification, occurs as highly reflective Arctic ice and snow melt away, allowing dark land and exposed ocean to absorb more sunlight.

CNN: Warmest Arctic temperatures for 2,000 years, says new study

The Flood Protection Association said compacted snow and ice would melt more slowly than snow on the ground.

The flow in the Mekong comes mainly from rainfall and some snow melt, not melting ice.
