Researchers at NOAA’s National Severe Storms Laboratory and the NOAA National Weather Service Weather Prediction Center are testing an experimental flash flood and intense rainfall forecasting tool.
When a tornado threatens a community, NOAA National Weather Service forecasters issue a tornado warning. Local emergency management agencies sound emergency tornado sirens or send out phone alerts. Broadcast meteorologists tell everyone to take shelter. But how does all of this help the public and how does the public respond?
For scientists at NOAA, Earth Day — and every other day of the year — is about getting to the bottom of some of the most pressing questions about the planet we call home: how it works, how it’s changing, and how humans are affecting it.
NOAA’s best severe-weather model just received an upgrade developed by NOAA researchers that will help the National Weather Service provide more accurate hazardous weather and aviation forecasts. Scientists are also using it to advance a wide array of future forecast tools.
The Big Thompson flood of 1976 was one of three major flash floods during the span of five years in the 1970s that killed more than 450 people across the country -- tragic events that helped spur the modernization of NOAA’s National Weather Service flood forecasting system.
This summer, more than 20 NOAA scientists will stay up late to learn why some thunderstorms form and grow at night, without the energy from the sun's heat. They will be participating in the Plains Elevated Convection At Night (PECAN), a large, intensive field campaign to collect data before and during nighttime thunderstorms in the western Great Plains from June 1 to July 15.
Weather forecasters rely on an incredibly large amount of information when they make forecasts and issue warnings. A new system, activated by NOAA’s National Weather Service last week, quickly harnesses the tremendous amount of weather data from multiple sources, intelligently integrates the information, and provides a detailed picture of the current weather.
NOAA researchers have developed a method to help forecasters better predict the severity of tornado outbreaks.
