对比研究7亿年至今的生物群落,发现历次冰川形成时期,有两个重要条件:首先,在足够宽阔的低纬度海域,那些能使云凝结核大量释放的生物群落大发生,其次,在中高纬度有利于水汽畅通输送的生物群落分布极广。
Using a DMT(Droplet Measurement Technologies) continuous flow streamwise thermal gradient cloud condensation nuclei(CCN) counter mounted on a Cheyenne ⅢA aircraft,aircraft measurements of CCN in about 20 flights over North China were conducted in the autumn of 2005 and spring of 2006.

Based on the cloud scheme of Chinese Academy of Meteorological Sciences(CAMS), awarm cloud model with prognostic variables of concentrations of aerosols,CCN and clouddrops was developed.
在中国气象科学研究院云模式的基础上,增加了气溶胶、云凝结核和云滴数浓度的预报量和微物理过程,改进了该模式的暖云物理方案。
The distribution of aerosol,CCN concentration generally decreases with the height.
边界层是气溶胶和云凝结核(CCN)最密集处,云区为1 176~2 465 m,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。
The results show that dust particles raised during duststorms increase the amount of large and giant cloud condensation nuclei in the atmosphere,lead to more large droplets activated at the early stage of cl.
结果表明:扬沙和沙尘暴天气增加大气中大核和巨核的浓度,促进云中水汽的活化,使降水提前出现,暖云和冷云降水量均大幅增加,但可忽略巨核增加对云光学厚度和反照率的作用;当矿物沙尘粒子同时作为有效的云凝结核和冰核参与云的发展时,冰核浓度增加使水成物有效半径减小,抑制了暖云和冷云降水,云内存留的大量冰晶增强云的光学厚度和反照率。
The concentration of cloud condensation nuclei is determined from surface and aircraft measurements at Mt.

The particles can be detected with a condensation nucleus counter.
这种粒子可以用凝结核计数器探测到。
Particles which are counted in condensation nucleus counters are very often not activated in natural cloud or fog condensation.
在凝结核计数器中被计下的粒子,在天然云或雾的凝结中往往很不活化。
We could find a significant effect on CCN concentrationwhen the aerosol distribution is different.
