摘    要:通过对2008年4月21日河北省正定1次飞机探测气溶胶垂直分布和云微物理结构的资料进行分析,结果表明:探测的气溶胶数浓度为10^2~10^3个/cm^3,平均直径为0.19~0.70μm;云滴数浓度为10^0~10^2/cm^3,云滴平均直径为4~15μm。边界层是气溶胶和云凝结核(CCN)最密集处,云区为1176~2465m,云底云滴数浓度低,蒸发释放核膜态粒子使得气溶胶进入云层后数浓度减少幅度较小,另云滴对CCN有消耗作用。气溶胶平均谱基本为双峰型,高层云区云滴增加促使气溶胶由核膜态向积聚模态、粗模态转变。云滴谱较复杂,具有单峰型和双峰型,云顸平均谱最宽。

关 键 词:气溶胶  云凝结核  微物理结构

Abstract:The data of the aerosol vertical distribution and cloud microphysical structure by one plane detection in Zhengding of Hebei on April 21st of 2008 were analyzed. The results showed that the fine aerosol particles concentration was 10~2-10~3 cm~(-3). The average diameter of the fine particles was 0.19-0.70 μm. The droplet concentration was 10~0-10~2 cm~(-3). The average diameter of droplet was 4-15 μm. The distribution of aerosol, CCN concentration generally decreases with the height. The cloud covered from 1 176-2 465 m , and droplet concentration in the cloud base was low;The fine aerosol average distribution followed bimodal distribution, The droplet distribution had bimodal and unbimodal distribution.
Keywords:Aerosol  CCN  Micro-physical structure
