Cloud Seeding

How much snow does cloud-seeding produce? Soon scientists will be closer to knowing the answer. NSF-supported researchers have begun a cloud-seeding experiment in southwestern Idaho. Dubbed SNOWIE (Seeded and Natural Orographic Wintertime Clouds -- the Idaho Experiment), the project is taking place in and near the Payette Basin, 50 miles north of Boise, Idaho.

SCHUSS. The term for a straight, downhill ski run. In the land of the "Greatest Snow on Earth" – Utah – SCHUSS is also the moniker for storm-chasing, Old Man Winter-style.

The subnivium, it's called, this refuge beneath the snow that's insulated and maintains a constant temperature. It's nature's igloo for all winter creatures great and small.

If you're planning to skate on a frozen lake or river this winter, ski on a snowy slope, or, when spring arrives, depend on snowmelt to refill your water supply, you may need to think twice. December-to-March may be less like the winters we remember.

Niwot Ridge, Colorado. It's 11,600 feet above sea level, and is home to a National Science Foundation Long-Term Ecological Research site. There scientists study snow – and what happens to our water resources when it begins to melt.
