A thunderstorm complex that toppled trees and knocked out power from Illinois to the Delaware coast brought to light a weather term with an obscure but intriguing history.

Colony of world's largest penguins may decline dramatically as Antarctic sea ice recedes this century, new study indicates.

A multisatellite observing system that was only a gleam in researchers’ eyes in the 1990s is now a key tool for monitoring Earth’s atmosphere. An ambitious follow-up project could yield up to ten times the data gathered by the current satellites.

To help their students and faculty study the atmosphere in detail, campuses worldwide rely on Unidata, the UCAR-based program that keeps a 24/7 stream of weather and other environmental data flowing to classrooms.

NCAR scientists are developing a system to relay updates on weather and road conditions to and from wireless-enabled vehicles.
