Forecasting Workshop Returns to In-Person Learning

NORMAN, OK (April 22, 2022) – About two dozen National Weather Service forecasters from across the country stepped into the weather event simulator this week as a flagship workshop returned to in-person instruction at the National Weather Center for the first time in two years. The weeklong workshop is the culmination of the Radar & Applications Course (RAC), an approximately 100-hour long, blended learning ...

Making Connections Between Weather and UAS

Tony Segalés Espinosa says his love of small-scale aircraft began as a kid, flying model aircraft with his dad. Today, that love transfers into engineering drones for severe weather research. Segalés Espinosa combines his robotics background and his electrical engineering knowledge to build severe weather research drones or uncrewed aerial systems. These systems will be utilized in field experiments by the NOAA ...

Translations and Beyond - Research Seeks to Improve Severe Weather Communication and Response in Spanish-speaking Communities

As a child, Joseph Trujillo Falcón was terrified of thunderstorms. The loud booms and crashes would have him hiding inside, until one day his mother dragged him onto the porch. She told him to look at the beauty within the storm. His perspective changed. Born in Peru, Trujillo Falcón moved from what can be described as a mild, coastal climate to the storm-riddled Midwest United States. “At the time, I was ...

OU Meteorologists to Intercept Hurricane Ida in Coastal Louisiana

NORMAN, OKLA. – Earlier today, the NOAA National Hurricane Center upgraded the storm gaining momentum off the United States Gulf Coast from a tropical storm to a hurricane, with sustained winds of more than 74 miles per hour. A research team led by Michael Biggerstaff, professor of meteorology in the College of Atmospheric and Geographic Sciences at the University of Oklahoma, is en route to Louisiana to deploy ...

Researchers Study Costliest Severe Thunderstorm Event

One year ago, a severe thunderstorm with extreme winds — called a derecho — tore through the Midwest United States. The event brought extensive damage — snapping power poles and damaging an estimated 37.7 million acres of farmland. NOAA estimates indicate this is the costliest thunderstorm event in recorded history for the United States, causing more than $11 billion in damage.Researchers at the ...

Guest Contributor: Using a Dual-Pol Radar Feature to Anticipate Downburst Development

Downbursts — an area of strong winds in a thunderstorm — can damage trees and buildings, disrupt air travel, and cause loss of life. Decades of work by scientists has revealed a lot of information about downbursts including certain features seen on radar, known as precursor signatures, that can help forecasters anticipate when a downburst might develop. However, downbursts are still quite challenging ...
