Abstract：The time distribution characteristics of lightning activities in Chongqing Wansheng are obtained through the statistical and difference analyses of thunderstorm days and lightning days by such methods as linear regression trend equation,climate tendency rate,Mann‑Kendall change‑point detection and Morlet wavelet analysis based on the data on thunderstorms observed manually from 1978 to 2012 by Wansheng Meteorological Observation Station and the data on lightning positioning in Wansheng monitored systematically from 2008 to 2020 by Chongqing Lightning Monitoring Network.

Key words：lightning activity characteristics;thunderstorm day;linear regression trend equation;climate tendency rate;Mann‑Kendall change‑point detection;Morlet wavelet analysis;evaluation model;time distribution characteristics

摘　要：利用重庆万盛国家气象观测站1978 ~ 2012年人工观测的雷暴资料和重庆市闪电监测网2008 ~ 2020年系统监测的万盛闪电定位资料，采用线性回归趋势方程、气候倾向率、Mann‑Kendall突变检验、Morlet小波分析等方法对雷暴日和雷电日进行统计和差异性分析，得到万盛的雷电活动时间分布特征。

关键词：雷电活动特征；雷暴日；线性回归趋势方程；气候倾向率；Mann‑Kendall突变检验；Morlet小波分析；评价模型；时间分布特征
