Propagation, Evolution, and Rotation in Linear Storms


PERiLS is one of the largest severe storms field campaigns taken on by the meteorological community. Set in the Southeast United States in the late winter to early spring months of 2022 and 2023, dozens of instruments from NOAA and mulitple research institutes and univeristies will be deployed hoping to gather more information about quasi-linear convective systems, or QLCSs. The PERiLS project aims to better understand how tornadoes form in this type of storm. These tornadoes, more common in the Southeast, pose a significant challenge to forecasters and emergency managers due to their rapid development.

Funding Agencies

PERiLS is funded by the National Science Foundation and NOAA (the NOAA component is under the VORTEX-USA umbrella).
