The National Weather Service reports that some snow accumulations from Monday's winter storm topped ten inches near Washington, DC.

据美国国家气象局报道，周一的冬季暴风雪导致华盛顿附近的积雪厚度超过10英寸。

The region relies on winter snow accumulation to provide long-lasting water supplies, says wildfire expert Jessica Holovsky with the US Forest Service.

美国林业局的野火专家杰西卡·霍洛夫斯基表示，该地区依靠冬季积雪来提供持久的供水。

They were combining radar measurements, satellite information, and snow accumulation data, and they say this allowed them to locate a valley that's hidden underneath the ice sheet.

综合了雷达勘测数据、卫星信息和积雪数据，他们找到了一个隐藏在冰盖下的峡谷。

As each year's snow accumulation lay on the surface, evaporation and melting caused the snowflakes slowly to lose their feathery points and become tiny grains of ice.

由于每年的雪花积累在表面之上，蒸发和融化使得雪花慢慢失去其羽状尖端而变成微小的冰粒。

It has, however been late on occasion. In 1962 snow accumulation caused the clock to ring in the new year ten minutes late and in 1976 the clock stopped when a piece of its machinery broke.

当然，大本钟偶尔也会出现“晚点”的情况。在1962年，由于雪花不断堆积，使得新年钟声比正常时间晚响了10分钟。而在1976年，因为一个机械部件断裂，大本钟干脆不“走”了。
