摘要
尘卷风是一种发生在对流边界层的垂直涡旋,多发生在干旱半干旱地区,其旋转过程中强上升气流携带大量沙尘粒子,成为沙尘气溶胶排放的一个重要起沙过程。然而,相对于沙尘暴研究,目前对尘卷风及大气边界层的起沙过程的认知相当有限。从尘卷风发生的时空变化、边界层特征、形成原因和输沙量4个方面对尘卷风当前研究状况进行总结,并指出当前尘卷风研究重点及未来研究方向。
Dust devils are vertical vortices in the convective boundary layer. They typically occur over the arid and semi-arid regions. A great quantity of dust particles is lifted by strong updrafts of dust devils, which is an important mechanism for dust aerosol emissions. However, compared to the sandstorm, our understanding of dust devils and their dust emissions in the atmosphere are rather limited. The paper mainly reviews the research progress of dust devils in the respects of temporalspatial variation, atmospheric boundary layer characteristics, formation mechanism and dust emission fluxes, and summarizes the major issues in current study of dust devils.
