摘　　要：为了研究不同地形条件下河南省雷暴的分布特征,在1971-2000年30年雷暴日数观测资料上,叠加河南省地理信息,进行了分析研究,得知河南省全年有3个雷暴多发区,第一个为豫南桐柏山高发区,第二个为豫西南伏牛山高发区,第三个为豫北太行山高发区;同时分别对该省春季、夏季和秋季的雷暴进行了分析,发现春季雷暴高发区主要位于信阳桐柏山区域,夏季雷暴高发区位于豫北太行山、豫西南伏牛山和豫南桐柏山区域,秋季雷暴高发区主要在豫北太行山区域,其次为豫南桐柏山区域。雷暴的发生具有显著的地域性,山区的雷暴日数多于平原地区,这对山区的防雷建设和人工影响天气作业提出了新的要求。For the purpose of finding thunderstorm distribution feature in Henan Province, with the help of GIS, the research were conducted based on the thunderstorm data from observation in Henan Province in recent 30 years. The results show that there are 3 high-incident areas of thunderstorm in whole year, the first is located in the South of Henan, the second is located in the South-west of Henan, and the third is located in the North of Henan. The days of thunderstorm in spring, summer and autumn are analyzed in the same way. The results show that the high- incident areas of thunderstorm in spring are located in South Henan ; the North , the South-west and the South of Henan are the high-incident areas of thunderstorm in summer ; the North of Henan is the high-incident area of thun- derstorm in autumn. The thunderstorm~ occurrence has the remarkable localization that the days of thunderstorm are more in mountain areas than in plain. These features put forward more severe demand for construclion of thunderstorm prevention and artificial weather influence in mountain areas.
