中文摘要: 根据2001年5—6月8架次的飞机探测资料，配合地面观测和卫星资料综合分析得出了西北地区春季云系的垂直结构宏微观特征，包括云厚、云底高度、云粒子浓度、含水量、有效半径、粒子谱分布函数等。降水性层状云厚平均约2000 m,低云含水量垂直方向上平均为0.07 g?m-3，中云含水量垂直方向上平均为0.03 g?m-3。对比分析降水云和非降水云系的微物理特征量，两者存在显著的差异，降水性层状云有效半径要达到10～16 μm。

Abstract:Observations from aircraft equipped with Particle Measuring System in May-June 2001，surface observations and satellite data have been analyzed to get macro and micro structures of cloud system over Northwest China, including cloud base height, cloud thickness, cloud particle concentration, liquid water content, effective cloud particle radius, and cloud particle spectrum function. The depth of stratiform clouds with precipitation is about 2000 m, The mean value of liquid water content of low clouds with precipitation is about 0.07 g?m-3, The mean value of liquid water content of middle clouds with precipitation is about 0.03 g?m-3. It is found that there are distinct differences between stratiform clouds with
and without precipitation, by comparing their macro and microphysics. The effective radius of stratiform cloud with precipitation needs to be as large as 10-16 μm.
