摘　　要：1人工影响天气机理与方法1.18人工影响天气碘化银催化剂研究进展碘化银(AgI)类催化剂是人工影响天气外场试验和业务作业中使用最广泛的催化剂,其核化效率和核化机制在很大程度上影响催化效果。在总结美国、中国和欧洲多个国家利用云室和风洞研究AgI类催化剂的核化机制、核化阈温及成核率的室内试验成果的基础上,梳理利用室内试验成果发展的AgI数值催化模式,旨在为下一步优选新型高效AgI类催化剂和改进数值催化模式提供借鉴。1 Mechanism and method of weather modification 1.1 Cable-car measurements of vertical aerosol profiles impacted by mountain-valley breezes in Lushan Mountain,East China In-situ field observations of vertical aerosol profiles for one month in complex terrain(Lushan Mountain,China)were carried out using a cable car,which resolved detailed vertical distributions of mountain aerosols with lowcost operation.Cable-car observations were conducted during the early morning and late afternoon,when mountain and valley winds dominated,respectively.The diurnal aerosol variations at the top and foot of Lushan Mountain were analyzed based on environmental and meteorological stations.The observations indicated that the mountain-valley breezes notably impacted the mountain-area aerosol distribution under weak weather conditions.
