NOAA Near-Term Weather Forecasts Get Powerful Boost from New Computer Model

Rapid Refresh (or RAP, lower right) performed better than the older RUC model (lower left) in predicting severe weather conditions that occurred in the Midwest on June 21, 2011 (upper right).

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

Building a Weather-Ready Nation

Luchenco on-screen video conference

This week, the Department of Commerce’s National Oceanic and Atmospheric Administration (NOAA) kicked-off a national dialogue to improve our nation’s readiness for extreme weather. At the Weather-Ready Nation: A Vital Conversation workshop, held in Norman, Okla., participants assessed why the nation has become more vulnerable to severe weather and identified ways to improve the public’s awareness, preparedness and response to future extreme events.

More than 1,000 lives have been lost this year to extreme weather, including about 550 from tornadoes. And the economic losses are equally staggering—at least 12 separate weather disasters, each with $1 billion or more in economic losses.

These impacts moved NOAA’s National Weather Service to launch an initiative called Weather-Ready Nation. The goal is to improve America’s readiness for weather events and save more lives and livelihoods. The Norman event is the first in a series of Weather-Ready Nation activities to be held across the country.
