摘要: 根据1997年在辽宁利用机载粒子测量系统(PMS)获取的探测资料,探讨了层状云中云滴谱、粒子数浓度在水平方向上的分布变化,并分析了温度、粒子含水量在水平方向上的变化特征。研究表明:云滴数浓度和云滴半径在水平方向上存在着较强的起伏性变化;层状云中温度在水平方向上总体变化不大;云中的云滴谱结构在水平方向上的起伏较大,存在3种变化规律;云中含水量在水平方向上的变化大,且与粒子数浓度存在正相关。

Abstract: In terms of the data of stratiform could microphysical structure from airborne particle measurement system(PMS) in 1997 in Liaoning province,the characteristics of cloud droplet spectrum,particle number concentration,temperature and water content of particle in the horizontal level were discussed.The results indicate that the number density and radius of cloud droplet in the horizontal level fluctuate strongly.Temperature changes little,while the spectrum structures of cloud droplet fluctuate strongly with three patterns.Water contents of stratiform cloud vary greatly,and have close positive relationship with particle number concentration.
