On winter mornings, ice and snow cover the entire city.

冬天的早晨，冰雪覆盖了整个城市。

Water equivalent of snow cover

积雪水当量

Seasonal snow cover and glacier are important components of global water cycling. Thus, it is necessary to monitor the seasonal snow cover, the depositing and melting of the glacier.

季节性雪盖和冰川是全球水循环中的重要成分，监测季节性雪覆盖的范围以及冰川的堆积和消融地带，对于理解全球水循环是十分必要的。

This is also reflected on the world map by the advance and retreat of snow cover.

在大地图上也能通过白雪覆盖的情景反映出来。

Local weather conditions, snow cover and ocean currents can also influence ice loss.

当地的天气状况，冰雪覆盖程度和洋流都影响着冰的消融。

Today the midlatitudes are warming up and the snow cover has mostly disappeared.

现今中纬度正在变暖，覆雪几乎完全消失。

But one phenomenon that may be significant is the way in which seasonal snow cover has continued to increase even as other frozen areas are shrinking.

需要注意这样一个明显的现象，尽管其他冰冻区域正在日渐减小，但季节性积雪所覆盖的区域却在持续地扩张。

Using remote sensing technique will effectively acquire large-scale snow cover information, and make up the deficiency of earth observing material in space.

使用遥感方法能够有效获取大范围的雪盖信息，弥补地面观测资料在空间上的不足。

Because of the ice-layer and snow cover, there is not sufficient light to shoot with ambient light and batteries lose their charge more quickly in cold weather.

因为有冰层和积雪，没有足够的光线投射背景光，电池在寒冷的天气中也会更迅速地失去电量。

The rate of melting in the Arctic isn't just a function of temperature change; local weather conditions, snow cover and ocean currents can also influence ice loss.

北极冰的融化速度加快只是气温变化的一种后果；当地的天气状况，冰雪覆盖程度和洋流都影响着冰的消融。
