The new system provides 8-hour forecasts of potentially dangerous atmospheric conditions over remote ocean regions

With policymakers and political leaders increasingly unable to combat global climate change, more scientists are considering the use of manual manipulation of the environment to slow warming’s damage to the planet.

The simple observation that leaves shrink when they dry out has far-reaching consequences for scientists studying how ecosystems work, a UA graduate student has discovered.

December 5, 2012 | When the weather is good enough for U.S. Air Force pilots to land their C-17 cargo jets on one of the ice runways at Antarctica’s McMurdo Station, they know they’ll probably see volcanic Mt. Erebus rising 13,000 feet into crystalline blue sky. Part of the reason they’ll get a clear view, and in turn a safe landing for passengers and cargo, will soon have to do with another Erebus. That’s the name of the new NCAR supercomputer dedicated to the real-time Antarctic Mesoscale Prediction System (AMPS) weather forecasts.

October 16, 2012 | Coronal mass ejections (CMEs) are powerful eruptions near the surface of the Sun that can disrupt satellites and power grids. Understanding what drives these space weather events may allow astronomers to predict impending CMEs so that appropriate measures could be taken to safeguard vulnerable technology on Earth. New observations by NCAR scientist Sarah Gibson of the Sun’s magnetic field and a phenomenon known as coronal cavities are providing an unprecedented glimpse into what triggers these massive eruptions.
