中文摘要: 利用球载摄像探空仪对梅雨锋降水云微物理结构进行了观测,得到云中5种类型粒子(冰晶、霰、雪片、冻滴、雨滴)直径、数浓度、质量浓度的垂直分布及各高度层上的温、压、湿分布。对观测结果的分析表明:在梅雨锋雨带的对流云团中,冰晶、霰和雪片对降水形成起着重要作用。
Abstract:Cloud micro-physical structures for mei-yu front rainfall were observed by using the balloon-borne Precipitation Particle Image Sensor during June and July 1999 at Shanghai.The observations including vertical distributions of various particle size,their number density and mass density are obtained.Analyses show that icecrystals,graupels,snowflakes and frozen droplets often coexist with the liquid phase in the convective cloud clusters inbanded in mei-yu front rainband.They and their interactions play important roles in the formation and evolution of rainfall.
