摘　　要：讨论了五台山和邻近平原地区雷暴和冰雹的时空分布。指出五台山是强对流天气的多发区。提出了对流风暴越过山脉的４ 种情况：（１） 在太行山脉的西侧停滞、减弱或消失。（２） 对流云团的中上部越过山脉演变为中高云。（３） 原有的对流云团越山后冲击出新的对流云团。（４） 对流云团正面越过山脉，形成下坡风暴。The temporal and spatial distribution of hail and thunderstorm in Wutai mountain and nearby plain region were discussed.Results show that it is in the Wutai mountain area that convective storms happened frequently.There were four possible cases of convective storms crossing over the mountain,e.g.① convective storms stagnate,decrease and disappear voer western Taihang Mountain;② the upper of convective cloud cluster across voer the mountain turns into medium and high cloud;③ the initial cloud cluster across over the mountain generates new convective cloud cluster;and ④ convective cloud cluster across over the mountain formates downslope storm.
