Abstract

Quasi-linear convective systems (QLCSs) are responsible for approximately a quarter of all tornado events in the U.S., but no field campaigns have focused specifically on collecting data to understand QLCS tornadogenesis. The Propagation, Evolution, and Rotation in Linear System (PERiLS) project was the first observational study of tornadoes associated with QLCSs ever undertaken. Participants were drawn from more than 10 universities, laboratories, and institutes, with over 100 students participating in field activities. The PERiLS field phases spanned two years, late winters and early springs of 2022 and 2023, to increase the probability of intercepting significant tornadic QLCS events in a range of large-scale and local environments. The field phases of PERiLS collected data in nine tornadic and nontornadic QLCSs with unprecedented detail and diversity of measurements. The design and execution of the PERiLS field phase and preliminary data and ongoing analyses are shown.

线性风暴的传播、演变和旋转（PERiLS）项目

准线性对流系统（QLCS）造成的龙卷风约占美国所有龙卷风事件的四分之一，但还没有任何实地活动专门侧重于收集数据以了解 QLCS 的龙卷风生成过程。线性系统中的传播、演变和旋转（PERiLS）项目是首次对与 QLCS 有关的龙卷风进行的观测研究。参与者来自 10 多所大学、实验室和研究所，有 100 多名学生参加了实地活动。PERiLS 实地研究阶段跨越两年，即 2022 年和 2023 年的深冬和早春，以提高在各种大规模和局部环境中拦截 QLCS 重要龙卷风事件的概率。PERiLS 实地阶段收集了九个龙卷风和非龙卷风 QLCS 的数据，测量数据的详细程度和多样性前所未有。图中展示了 PERiLS 实地阶段的设计和执行情况，以及初步数据和正在进行的分析。
