Research yields new tool to achieve a Weather-Ready Nation 
Starting today, Commerce's National Oceanic and Atmospheric Administration (NOAA) is using a sophisticated new weather forecast computer model to improve predictions of quickly developing severe weather events including thunderstorms, winter storms and aviation hazards such as clear air turbulence.
The Rapid Refresh now provides NOAA's most rapidly updated weather forecast, replacing an older model that served a similar function. The Rapid Refresh, developed by NOAA's Earth System Research Laboratory  in Boulder, Colo. and NOAA's National Centers for Environmental Prediction  (NCEP) in Camp Springs, Md., updates every hour with a new forecast extending out 18 hours for North America. Such forecasts are especially important in aviation, where fast-developing weather conditions can affect safety and efficiency, but they are equally important for severe weather and energy-related forecasting. | Full release
