汶川地震灾区的雷电灾害气候特征研究分析

利用汉川地震重灾区和极重灾区四川境内35个气象台站1981年1月～2010年12月30年的气象观测资料，包括月、年雷暴日数，年雷暴初、终日期，初终间日数，采用气候趋势系数方法和数理统计、概率分析等方法，对汉川地震灾区雷暴的时空分布、变化规律和年代（际）气候变化趋势进行了分析和初步研究。 

The Thunderstorms Climate of the Wenchuan Earthquake Zone

This study uses climate trend coefficient method，mathematical statistics and probabilistic method to study the temporal and spatial distribution，Variation and Inter-annual trend of the thunderstorms by using the thunderstorm observation data（including monthly average thunderstorm days，annual thunderstorm days， the first and last date of thunderstorm of the year，the days between the beginning and end date of 35 weather stations in severely damaged area and most damaged area in Sichuan territory of Wenchuan earthquake from January 1981 to October 2010.
