本文综述了与航空旅行的安全性和生产率有关的尾涡的形成、运动和持续性。它强调了Widnall（1975）在本系列中的评论以来的发现或变化。这篇评论还探讨了涡的可预测性（特别是在寿命方面）、多个涡旋对的耐久性、涡旋衰减和涡旋崩溃预期之间的争议、可能影响流动的多种湍流类型、旋转和轴向速度场之间的丰富相互作用涡旋中，主导后期行为的各种大气和地面相关因素，几次尾流的反弹，以及仍然无法解释的漩涡爆发。文章还简要介绍了检测和控制的前景。
▪ Abstract This review surveys the formation, motion, and persistence of trailing vortices as relevant to the safety and productivity of air travel. It highlights findings or shifts made since Widnall's (1975) review in this series. This review also examines the predictability of the vortices (particularly in terms of lifespan), the durability of multiple vortex pairs, the controversy between expectations of vortex decay and of vortex collapse, the many types of turbulence that may influence the flow, the rich interplay between the rotational and the axial velocity fields in the vortex, the various atmospheric and ground-related factors that dominate the late behavior, a few instances of wakes rising back, and the still unexplained bursting of the vortices. The article also briefly covers prospects for detection and control.
