Connecting Data to Phenomena Drives Radar Researcher to Investigate Winter Weather Hazards

On warm, sunny days, Jacob Carlin can be found creating his own severe weather – radar simulations of winter storms that help forecasters make short-term predictions about what can't be seen inside a storm. Carlin analyzes dual-polarization radar data as a research scientist at the Cooperative Institute for Severe and High-Impact Weather Research and Operations (CIWRO) at the University of Oklahoma. By studying ...

Researcher Bridging Gaps in Flash Flood Research

When Hurricane Ian made landfall in Florida in late September, destructive mass flooding was imminent, but not all flash floods are as easy to predict. Forecasters must have access to a variety of data to issue flash flood warnings, and researcher Humberto Vergara Arrieta and his hydrology team are working to make it easier to communicate life-saving watches and warnings to the public. Vergara Arrieta is the lead ...

Hazardous Weather Testbed Allows Researchers and Forecasters to Experiment With New Weather Software

During severe weather, colored polygons on radar maps represent traditional weather warnings. But for researchers with the Cooperative Institute for Severe and High-Impact Weather Research and Operations (CIWRO), the future of forecasting isn’t tied to a static shape. Adrian Campbell and Rebecca Steeves, research associates for CIWRO at the University of Oklahoma, were part of a team that recently conducted ...

OU receives $888,000 grant to study Arctic clouds - Research will address blind spot in cloud microphysics

A research team from the University of Oklahoma has been awarded an $888,000 grant to explore how Arctic clouds form over time and to unlock secrets about the release of heat and radiation from the atmosphere. The three-year grant was one of 22 projects totaling $14 million funded by the U.S. Department of Energy this month to advance fundamental scientific understanding of atmospheric processes. Andrew Dzambo, ...

CIWRO Research Leads to Improved Storm Forecasts for Spanish Speakers

Joseph Trujillo Falcón saw confusion among how Spanish speakers were receiving severe storm warnings while he was an undergraduate broadcast meteorology student at Texas A&M University. Direct translations from English didn’t carry the same urgency across the wide range of dialects. This issue spurred him to change his professional focus from forecasting to bilingual risk and crisis communication, and he joined ...

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 ...
