摘要
利用山西省108个气象站1971年～2000年30a地面气候资料,对山西省平均雷暴日的时空特征进行了统计分析,结果表明:山西省平均雷暴日数总体上为北部多,南部少,东部山区多,中西部盆地和山区少。大同北部,朔州、忻州西部,五台山,晋中的榆社,阳泉的盂县为雷暴多发区,而运城为雷暴发生最少的区域;但各月分布存在明显的差异。夏季为雷暴高发季节,7月最易发生雷暴。
Using the surface climate data of 108 station in Shanxi province 1971 -2000, the Spatial- temporal characteristics of the number of thunderstorm days were analyzed. the result shows： Generally, the probability of thunderstorm happening in the north and east mountainous area is bigger than the south, the west and middle basin. The higher probability area includes the north of Datong, the west of Shuozhou etc, Yuncheng is the lower probability area correspondingly. There are obvious differences in diffrent months. July is the month with the highest probability of Thunderstorm.
