The Propagation, Evolution, and Rotation in Linear StormsProject (PERiLS) was a field campaign led by the National Severe Storms Laboratory in 2022 and 2023 to study how tornadoes form within squall lines. [1] [2] [3] [4] The project was led by Daniel Dawson at Purdue University. [5] The project was the first to study and observe tornadoes within quasi linear convective systems (QLCSs). [6]
The project aimed to study the environments of QLCSs capable of producing tornadoes, while documenting mesocyclone formation and evolution within tornadic QLCSs. The project also studied damage produced by QLCSs. [1] Anthony Lyza was a coordinating scientist on the PERiLS Project. [7]
The project was primarily funded by two grants provided by the National Oceanic and Atmospheric Administration: [5]
