| 摘 要： | 利用云和降水探测设备（DMT-PMS）对一次层状云降水过程进行了探测。分析发现CAS（云及气溶胶粒子探头）在该弱降水云中测得的云粒子平均浓度大于FSSP在其他地区层状云中所测平均值，CIP（二维云粒子图像探头）与2D-C及2D-GA2所测冰晶粒子平均浓度接近，PIP（二维降水粒子探头）与2D-P所测降水粒子平均浓度相当。观测发现云区雪晶浓度与冰晶浓度呈正相关关系，在冰晶浓度〈10^4个／m^3时，雪晶、冰晶浓度之比与冰晶浓度为负相关关系；在冰晶浓度〉10^4个/m^3的时刻，雪晶、冰晶浓度之比不因冰晶浓度变化而变化。温度为-10～-12℃的云区云水条件丰富，有较多的冰晶在该层孕育；降水粒子在温度-7～-10℃的云区生长。温度为-5～-7℃的云区云水不丰富，降水粒子蒸发变小；温度为-4～-5℃的云区仅有少量的降水粒子。

| Abstract: | A stratiform cloud was measured with a Particle Measurement System(PMS)produced by Droplet Measurement Technologies(DMT)and mounted on a Y-12 aircraft in spring of 2008,Beijing.It was found that the average concentration of cloud particles measured by CAS(Cloud and Aerosol Spectrometer)was bigger than those values measured by FSSP in other areas of north China.It was also found that the average concentrations of ice particles measured by CIP(Cloud Imaging Probe),2D-C and 2D-GA2 were all similar.A positive c... |
