摘　　要：利用石家庄16个县(市)1959—2007年的资料(包括县志),对石家庄冰雹的时空分布特征、冰雹路径等进行了综合分析。分析表明:①石家庄地区降雹日数年变化存在1、11、12和25年的周期性变化,在1971和2003年出现突变;②5月下旬至7月中旬是石家庄降雹盛行季节,一天中降雹多出现在14:00—20:00;③石家庄降雹西部山区多于东部平原,平原上的多雹区一般在河流或古河道附近;④通过资料分析,划分3道人工防雹作业防线,适当增加防雹作业点,科学合理的进行防雹作业点布局,开展阶梯式人工防雹作业。Using the data from 16 counties(cities) of Shijiazhuang from 1959 to 2007(including county annals),an analysis is made of the spatial and temporal distribution of hails in Shijiazhuang and their paths.The results indicate:(1) There were cyclical changes with the periods being 1,11,12,and 25 years in the number of hail days in Shijiazhuang;mutations appeared in 1971 and 2003.(2) Hails in Shijiazhuang occurred most frequently from late May to July,14:00 to 20:00.(3) Hails occurred more frequently in the western mountain areas than in the eastern plain;more in the areas near the rivers.(4) Through analysis,three hail suppression operation lines are set up,and hail suppression points increased,so to rationalize the arrangement of hail suppression points and carry out the stepwise hail suppression operations.
