地球和火星上的尘暴中的粒子提升已经从许多不同的角度进行了研究，包括尘暴如何影响这两颗行星的尘埃循环。在这里，我们审查我们目前的理解尘埃卷风的颗粒夹带检查结果在地球和火星上的实地观测，实验室实验（在地面环境和火星模拟条件），和分析建模。通过结合从这三种方法中获得的见解，我们提供了一个详细的概述粒子升降过程之间的相互作用，由于机械，热，电动和压力效应，以及这些过程如何适用于地球和火星上的尘暴。实验和观察表明，在地球和火星上适当的条件下，尘暴是有效的尘埃提升者。然而，尘暴研究尚未确定在尘暴中任何给定时间起作用的每个组成过程的单独作用。
Particle lifting in dust devils on both Earth and Mars has been studied from many different perspectives, including how dust devils could influence the dust cycles of both planets. Here we review our current understanding of particle entrainment by dust devils by examining results from field observations on Earth and Mars, laboratory experiments (at terrestrial ambient and Mars-analog conditions), and analytical modeling. By combining insights obtained from these three methodologies, we provide a detailed overview on interactions between particle lifting processes due to mechanical, thermal, electrodynamical and pressure effects, and how these processes apply to dust devils on Earth and Mars. Experiments and observations have shown dust devils to be effective lifters of dust given the proper conditions on Earth and Mars. However, dust devil studies have yet to determine the individual roles of each of the component processes acting at any given time in dust devils.
