| 摘 要： | 利用装载有粒子测量系统（PMS）的飞机对2007年8月15日甘肃省张掖市民乐县夏季非降水层状云进行了一次探测飞行，通过获取的资料分析了云层结构、云滴的垂直分布、液态含水量、谱特征等。结果表明：（1）此个例中云层结构明显，云中存在逆温层；（2）云中平均含水量为0．012g／m^3，含水层主要集中在4100～4200m与4700—5000m层之间；（3）此云系符合Bergeron提出的催化云一供水云相互作用导致降水的概念模型，可以在催化云中进行人工引晶来达到增加降水的目的。

| Abstract: | The PMS probes were used to measure microphysical parameters of a summer stratus on August 15, 2007 in Minle of Gansu Provinc. The cloud structure including particle＇ s vertical distribution, liquid water content and particle spectrum type was analyzed. Results show that： （ 1 ） the cloud structure of the stratus is clear, and there is an inversion layer in this cloud; （2） the average of liquid water content is 0.012 g·m^-3 in the cloud, and mainly concentrated in the layers of 4 100 -4 200 m and 4 700 -5 000 m; （3） this cloud accords with the Bergeron＇ s catalytic cloud and water cloud interaction model, so we can seed crystals to achieve the objective of increasing precipitation. |
