| 摘 要： | 利用机载粒子探测系统(PMS,ParticleMeasurementSystem)对1990年9、10月和1991年4月的春秋两季层状云进行了云及降水的微物理特征探测,分析了云微观特征和垂直分布,初步探讨了气溶胶对云的影响。结果表明,华北地区层状云的基本特征为云滴数浓度79.2cm-3、液态含水量0.03g.m-3、有效直径11μm并有垂直差异;云下气溶胶数浓度与云滴数浓度两者之间存在正相关关系,但其定量关系还有待于进一步研究。

| Abstract: | Measurements of stratus cloud microphysical properties were carried out in Hebei Province in October 1990 and April 1991 using a aircraft PMS(Particle Measurement System).The analysis results will be useful for studies on global climate change,satellite remote sensing and aircraft measurement.In this paper,the cloud micro-properties and vertical structure are preliminarily analyzed,and the relationship between aerosol and cloud droplets is also analyzed.The results show that,in the early 1990s,the cloud-droplet number concentration is 79.2cm~(-3) and the liquid water content is about 0.03gm~(-3).The effective diameter for stratus cloud drops is around 11m and it varies vertically.There is a positive correlation between aerosol number concentrations below the cloud base and cloud droplets number concentrations. |
