摘　　要：降水微物理过程是对空中雨滴的蒸发、碰并和凝结等演化过程的最直接描述。对降水过程中微物理特征的分析,有利于提高对云体的认识,为降水估计与数值模式参数化提供技术支撑。研究依托中国气象科学研究院灾害天气国家重点实验室在广东龙门建立的超级观测站,基于C波段调频连续波雷达高时空分辨率的多普勒功率谱数据。分析了2020年6月6-9日(前汛期),受西南季风影响,形成的一次持续时间长、累积雨量大、降水分布不均的降水过程中的几种典型对流单体的空中微物理特征。The precipitation microphysical process is the most intuitive description of the evolution process of evaporation,collision and condensation of raindrops in the fall path.The analysis of the microphysical characteristics in the precipitation process is meaningful to improve the understanding of the cloud and provide technical support for precipitation estimation and numerical model parameterization.This study takes the super observation station established by the Academy of Gas Sciences in Longmen,Guangdong as the experimental base,based on Doppler power spectrum data with high spatial and temporal resolution.The microphysical characteristics of several typical convective cells in the precipitation process with long duration,large cumulative rainfall and uneven precipitation distribution formed by the southwest monsoon during the period from June 6 to 9,2020(pre-flood season)are analyzed.
