| 摘 要： | 利用20062008年湖北省雷电监测定位网的定位资料，对武汉市雷电分布的时间特性进行分析。并将定位资料与武汉国家基本气象站的天气现象日值观测资料进行对比，从雷暴日这一观测要素上分析两种资料存在的差异及主要原因，以便更好地为雷电自动监测逐步取代人工观测提供参考。分析结果表明：武汉市的雷电活动以负闪为主，负闪占总闪的比例高达96．1％，且具有明显的月变化和日变化特征。雷电定位的雷暴日数普遍高于人工观测记录的结果，且在雷电高发月份，雷暴日数相差较大，但两者分布趋势大体相同。随着雷电自动监测资料的积累，可以消除人工观测资料存在的局限性。

| Abstract: | The temporal distribution features of lightning in Wuhan has been analysed on the basis of location data of Hubei lighthing monitoring and locating network from 2006 to 2008.To find out the differences between the two kinds of observation datas and the reason for the differences in the view of thunderstorm days,the contrast of the lightning location data and weather phenomenon observational data from Wuhan weather station has also been made.It can provide a reference for the automatic detection of lightning... |
