利用定远国家气象基本站1957-2011年逐月雷暴日资料，对定远县雷暴日数变化趋势进行了数理统计分析，并进行了Mann—Kendall突变检验，结果显示：定远县年雷暴日数总体呈现减少趋势，年平均雷暴日数为31.4d，气候线性倾向率为-1.569d/10a，月平均雷暴日数呈现单峰型，峰值出现在8月，平均为11d，20世纪60年代最多，20世纪90年代最少。夏季最多，冬季最少，春季比秋季多。20世纪60年代中期到20世纪90年代末期雷暴呈现减少趋势，20世纪80年代初期之后就呈现显著减少，M-K检验显示下降突变时间出现在1968年。

The Dingyuan national meteorological basic station 1957-2011,monthly data of thunderstorm days, through mathematical statistical analysis of thunderstorm in Dingyuan County,trend,and the Mann Kendall mutation test. The results showed that the Dingyuan County annual number of thunderstorm days overall decreasing trend,the average annual number of thunderstorm days 31.4d,climate linear trend rate for-1.569d/10a,the monthly average number of thunderstorm days showed single peak type,the peak in August,with an average of 11 days. In the 1960s most,in the 1990s at least. Summer is the most,the least in winter,spring is more than the fall. From the 60s to the end of the 90s,the thunderstorm showed a decreasing trend. After the early 80s,it reduced significantly,and the M-K test showed that the decrease of the mutation time appeared in 1968.
