Experts Preview Major Study On Tornadoes In Southeast United States

 

On Monday, February 28, NOAA and partner researchers will offer a public webinar to preview one of the largest and most comprehensive severe storm field campaigns to date, which begins on March 1 across the southeast United States.

Storms in this region can pose a higher risk to people and property for two reasons. First, some thunderstorms and the tornadoes they produce can be challenging to predict in advance because they often develop and evolve quickly. Second, the Southeast U.S. tends to be more vulnerable because of unique scientific and socioeconomic factors. For example, previous research has shown the frequency of nighttime tornadoes, the amount and distribution of mobile/manufactured housing, and more significant population density relative to other tornado-prone areas in the U.S.

Called PERiLS (Propagation, Evolution, and Rotation in Linear Storms), the campaign will deploy dozens of instruments to measure the atmosphere near and inside storms. Researchers will focus on quasi-linear convective systems that produce tornadoes, commonly known as squall lines. They will gather data in predefined areas from the Missouri Bootheel southward to the Gulf Coast and from the mid and lower-Mississippi Valley eastward to the foothills of the Appalachian Mountains. NOAA and the National Science Foundation fund the project.

WHAT: Virtual overview of the PERiLS research project, a virtual tour of research vehicles, and audience Q&A

WHEN: Monday, February 28, 2:30 – 4:00 pm E.T. (USA)
