UW students create, harvest fog in campus ‘hoop house’

By Sandra Hines via UW Today

In the fog chamber, a thick cool mist rolls from one end to the other blurring glasses, wetting caps and coats and sending water dripping down the latest test panel.

These figures illustrate the shift of cloud cover associated with the jet streams over land by latitude over the past 40 years. In the north, the cloud cover is slowing moving north and in the south cloud cover is shifting south. This change supports previous findings that the jet streams are shifting toward the poles.

Changes in cloud distribution explain some weather patterns

By Nancy Gohring
via UW News and Information

Regional cloud changes, such as those that result in less rain during monsoons in India and those that indicate a widening of the tropics, may be as important to watch as the overall amount of cloud cover, new University of Washington research indicates.

Greenland ice core shows Antarctica vulnerable to warming

By Vince Stricherz
via UW News and Information

An international study indicates the last interglacial period more than 100,000 years ago could be a good indicator of where the planet is heading in the face of increasing greenhouse gases and warming temperatures globally.

Salmon runs boom, go bust over centuries

By Sandra Hines
via UW News and Information

Salmon runs are notoriously variable: strong one year, and weak the next. New research shows that the same may be true from one century to the next.
