【摘要】 在人工增雨作业的同时 ,利用机载粒子测量系统对一次降水云系的探测资料进行了深入分析 ,给出了云和降水的宏微观结构演变特征 .研究表明 :(1)层状云中的中小尺度降水云区 ,是造成地面降水分布不均匀的物理原因 ;(2 )云滴浓度与平均直径之间呈负相关关系 ;(3)云滴谱的垂直分布是典型的 3种类型 ;(4)层状云微结构在水平方向上的起伏较大 ,存在 4种不同类型 .更多还原

【Abstract】 A case study is made for a precipitation process, its evolution of microphysical structure features is analysed by using PMS data, and rain enhancement potential is discussed.The results show:(1)The meso micro scale precipitation cloud in stratiform cloud causes the physical factor of uneven precipitation.(2)Between cloud droplet and average diameter are negative correlation factor.(3)The vertical distribution of cloud droplet spectra has three typical sorts.(4)The microphysical structure of stratiform cloud on horizon has four different sorts.更多还原
