摘　　要：利用黑龙江省80个气象台站38 a的降雹资料,应用统计方法对黑龙江省的降雹规律进行分析,得到了黑龙江省冰雹的时间和空间分布特征。空间上,黑龙江省冰雹天气分布中北部多,东南、西南部少;时间上,降雹存在明显的日变化,基本都集中于10-20时;冰雹天气年际变化明显,70年代至今,年代平均降雹呈现减少趋势。Using the 38 years hail data of 80 meteorological stations,analyzed the temporal and spatial distribution characteristics of hail in Heilongjiang province by statistical methods.The results showed that the hail weather happened in the central and north areas was more than in the other areas,and in the southeast and southwest areas was less.For the temporal distribution,the hail distribution had obvious diurnal variation,it occurred between 10:00 to 20:00 basically.Besides that,interannual variation of the hail was also significantly,the amount of annual average hail is decreased since 1970s.
