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 ...

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.
