摘　　要：大气湍流是一种无序的、非确定性的大气运动,它可提高云滴碰撞效率,加速云滴增长速度,在云和降水形成及发展过程中起着十分重要的作用。本文综述了国内外近60 a来云中湍流的研究进展,重点介绍了云宏微观结构特征及云中湍流对云滴碰并增长方面取得的研究成果,以期为进一步观测研究云动力学过程、完善湍流-云微物理相互作用理论及优化云参数化方案提供重要参考。Turbulence is an unregular atmospheric motion.Through increasing the collision efficiency of cloud droplets and accelerating the growth rate of cloud droplets,it plays an important role in the processes of cloud and precipitation formation and development.The studies of turbulence in clouds during recent decades are summarized in this paper.This paper mainly introduces the research results of the collision and growth of cloud droplets as well as the micro and macro characteristics of cloud structures.The contents in this paper are expected to im⁃prove observations and research on cloud dynamics processes,turbulence-cloud microphysical interaction theory,and optimization of cloud parameterizations.
