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 ...

This data plot shows real-time analyses from the combined data of both OU SR mobile radars. The real-time analyses were conducted by Addison Alford and Gordon Carrie (SoM). The left panel shows the maximum wind observed east of New Orleans by the SRs at 1500 meters above ground. The right panel shows the time at which that maximum wind occurred. The plot highlights the wind maximum associated with the The Shared Mobile Atmospheric Research and Teaching Radar (SR) 2 deployed near Franklin, Louisiana, during Hurricane Ida in late August 2021.
