摘　　要：夹卷混合过程表征了云和环境空气之间的相互作用,是云物理和动力过程中不确定性最大的过程之一。它影响着暖云降水形成过程,气溶胶间接效应的强度,云-气候之间的反馈等。本文总结了夹卷混合机制的含义和分类,云降水物理和光学性质的重要性,以及夹卷混合过程的定量描述和参数化。在此基础上,指出了夹卷混合过程研究的难点和未来的研究方向。The entrainment and mixing process characterizes the interaction between cloud and ambient air,which is one of the most uncer⁃tain processes in cloud physics and dynamics.The entrainment and mixing process affects the formation of warm cloud precipitation,the eval⁃uation of indirect effects of aerosols,and feedback between cloud and climate.This article summarizes the definition and classification of dif⁃ferent entrainment-mixing mechanisms,the effects on the physical and optical properties of cloud and precipitation,and the quantitative de⁃scription and parameterization of the entrainment-mixing process.Difficulties and future perspectives of the research on the entrainment and mixing process are also pointed out.
