Black Sheep of the Atmosphere: Ground-Level Ozone

While ozone is beneficial high in the stratosphere, this compound is a health hazard when found lower in the atmosphere. Researchers from NCAR and their colleagues are learning how, where, and why ground-level ozone forms. Read on to learn more about their research efforts.


Storms Roaring Through the Night

Discover the science behind monstrous storms called Mesoscale Convective Systems, which torment the Midwest U.S. during warm spring and summer months. Components of these storms are the topics of study for a field program lead by NCAR scientists during the summer of 2003. Read on to learn more about these storms and how they are studied.

Discovering How the North Atlantic Oscillation Drives Climate Change

NCAR scientist James Hurrell and his colleagues are seeking to understand climate change in the North Atlantic region. Using computer models, they identify the driving forces behind the North Atlantic Oscillation (or NAO), a pivotal force affecting the climate of the Eastern United States, Europe, the Middle East and Northern Africa. Read on to learn more about how the NAO affects climate.
