摘　　要：2011年夏季,北京市人工影响天气办公室组织了吸湿性焰剂的飞机播撒试验,选取八达岭长城西北的淡积云作为催化对象。试验期间,使用装备了云探测设备的运12飞机进行播撒及云微物理探测。在6月1日的试验中,运用差异化策略分别对不同的淡积云实施了催化,探测发现云中出现了符合暖云增雨概念模型的微物理反应。随后在晴空区实施了烟羽探测试验,通过在吸湿性焰剂烟羽区的穿刺飞行,获得了正在扩散的吸湿性焰剂的粒子谱,了解了播撒后扩散区的微物理特征。In summer 2011, a warm cloud modification experiment was performed by the Beijing Weather Modification Office. Cumulus humilis over the Great Wall at Beijing Badaling was selected as the seeding target cloud, and hygro- scopic flares were ignited at the cloud base level. Seeding and in-situ observations were conducted by a Y-12 aircraft equipped with a seeding device and cloud physics probes. Different strategies were used in an experiment on 1 June. A microphysical response consistent with the warm cloud seeding conceptual model was observed after seeding. The plume of the flare was subsequently measured in a clear zone, and the particle size distribution of the hygroscopic flare was il- lustrated.
