Scientists expand PERiLS tornado study for second year of research

Hundreds of research scientists from across the country will track severe storms this spring in an attempt to better understand how prominent tornadoes in the southeastern United States form. PERiLS (Propagation, Evolution and Rotation in Linear Storms) is one of the largest and most comprehensive field studies of its kind, examining the conditions before, during and after quasi-linear convective storms – ...

OU Engineers Offer Glimpse Into Future with State-of-the-Art Radar Technology

An estimated quarter-million lines of code were required for computer-generated imagery in the movie “Twister,” giving audiences a big-screen view of simulated tornadoes. But that’s only a fraction of the technology required to track the real storms. University of Oklahoma radar engineers have already created approximately 1.8 million lines of code to operate the most advanced weather radar in ...

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, ...
