针对山西省2010-05-27一次层状云降水过程,利用机载DMT探头和Parsivel激光降水粒子谱仪进行探测试验,分析了云微物理特征,并对空中和地面雨滴谱进行比较。结果显示,空中云垂直和水平结构分布不均匀,CDP,CIP 探测最大粒子浓度分别为165.20 cm-3、1.08 cm-3。地面雨滴微物理量的平均值说明此次降水是典型的层状云降水,雨强主要由雨滴数密度决定,雨滴微物理参量随时间变化而分布不均匀。结合粒子图像和雨滴特征量分析空中雨滴谱随高度的分布时发现,此次降水是冷云和暖云降水共存。

The cloud microphysical properties of a stratiform cloud in Shanxi on 27 May 2010 were analyzed based on the airbrone DMT probes and Parsivel laser precipitation particle spectrometer. The results showed that the vertical and horizontal structure of clouds was uneven. The maximum concentration values sampled by CDP and CIP were 165.20cm-3 and 1.08cm-3 respectively. Average value of microphysical features of surface raindrops indicated that it was a typical stratiform cloud precipitation. Rainfall intensity is mostly decided by raindrop concentration. Temporal distribution of raindrop microphysical parameters was not even. The precipitation was the coexistence of cold cloud and warm cloud precipitation.
