NOAA's upcoming weather forecast model zeros in earlier on severe weather
Research behind the High Resolution Rapid Refresh weather forecast model
3 March 2014
When it comes to weather, the more you know and the sooner you know it, the safer and better prepared you can be.
Later this year, NOAA’s National Weather Service will usher into daily operations a sophisticated model, developed at the Earth System Research Laboratory (ESRL), called the High-Resolution Rapid Refresh or HRRR.
Providing forecast information at a resolution four times finer than what is currently used in hourly-updated NOAA models, the HRRR is a “game-changer,” says Stan Benjamin, a research scientist and project lead at ESRL's Global Systems Division. That’s because it can differentiate between rotating and non-rotating storms, predict damaging straight-line windstorms called “derechoes”, and provide forecasters with improved information about heavy snow bands found in winter storms.
The HRRR’s two-year testing phase has yielded successful results on a number of severe weather events such as the June 2012 derecho that struck the Washington, D.C. area and demonstrated on the animated graphic at the right.
