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 ...
