  • NASA Works to Improve Short-term Weather Forecasts

    2008April 6, 2011

    NASA scientists are using an infra-red sounder in space to improve short-term weather forecasting.

  • Electric Ice

    2006Sept. 20, 2011

    Imagine looking inside a million clouds. That's what NASA researchers have done using the TRMM satellite to explore the strange connection between Lightningand ice.

  • Electric Hurricanes

  • Giant Atmospheric Waves Sighted Over Iowa

    2007April 6, 2011

    Last week, cameras in Iowa captured a giant atmospheric wave passing over Des Moines--see the movie in today's story. Atmospheric scientists believe these waves, called undular bores, may be more common and important than previously thought.

  • Noxious Lightning

    2007April 6, 2011

    Lightningis more than just heat and light: it's a chemical factory that produces a natural pollutant called "NOx" that can affect both local air quality and global climate. NASA scientists are developing new ways to monitor LightningNOx from Earth orbit.

  • Modeling Climate at Warp Speed
