The National Center for Atmospheric Research hits the ripe old age of 50 this year. But the center in Boulder is using the latest in satellites and supercomputers to study some even older problems -- like hurricanes and tornadoes. Don't think of that work being done in a drab lab though -- some of it's performed in a dramatic building that famed architect I.M. Pei designed early in his career. Sarah Hughes speaks with Richard Anthes, president of NCAR's parent organization, and with Lucy Warner, the center's communications director, about NCAR's history and the role it plays in scientific discovery today.
