Advances in the studies of turbulence properties in the cloud and the role of turbulence in cloud and precipitation

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 improve observations and research on cloud dynamics processes, turbulence-cloud microphysical interaction theory, and optimization of cloud parameterizations.
