| 摘 要： | 尘卷风是一种发生在大气对流边界层内，能将沙尘或者碎屑等物体扬到高空、具有温度较高的低压核心和较短生命周期的旋风，是自然界中一种最常见的自然现象，也是气象学中最独特的内容。回顾尘卷风的研究历史，主要包括尘卷风的气象要素与环境效应，尘卷风研究的三种方法及取得的成果，粉尘颗粒在尘卷风中的悬移运动及其分层机制，粉尘活动与颗粒荷电，提出了进一步研究的主要内容。 |
| 关 键 词： | 尘卷风 沙尘暴 颗粒荷电 气固两相流 |

| Abstract: | Dust devils are unique meteorological phenomena,occurring in the atmosphere boundary layer.Dust devil,usually of short duration,has a low pressure and warmcore,swirling dust,debris,and sand to high levels.This paper reviews the advances of dust devil studies,including the physical characteristics of dust devils and their environmental effect;some results obtained through three kinds of research tools-observation,experiment and numerical simulation;the particle transportation in the air flow field of dust devil and the dust stratification;the electrostatic field by particulate impact.Some aspects are finally summarized for further investigations. |
| Keywords: | dust devil dust storm particulate electrostatic effect gas-solid two-phase flow |
