中文摘要: 利用二维雹云模式模拟了济南地区1996年7月24日出现的一次冰雹过程，模拟结果表明对雹云26个主要微物理过程双参数化能较细致地描述强对流过程的热、动力反馈和微物理特点。根据计算结果，对该次冰雹过程进行了AgI催化试验，结果得出在云发展初期对暖底雹云实施高浓度的冰晶催化，可起到减少地面冰雹和增加地面降水的作用。

Abstract:The physical analysis and numerical simulation of a hail event in Jinan on July 24,1996 was made with a two dimension hail cloud model.The simulation results show that the model can describe in detail the character of feedback of thermodynamic and dynamic processes and microphysical processes in the hail choud.Based on the computed results,the silver iodide seeding experiment is conducted in the hail event,and it is concluded theoretically that cloud seeding with high concentration of artificial ice crystal at forming period of cloud may decrease surface hail and increase surface precipitation.
