摘　　要：利用岳阳地区6个气象台站1960—2009年雷暴日资料,采用绝对变率、气候倾向率、相关检验法等方法,分析了岳阳地区各地域的变化特征。结果表明:(1)初、终雷暴日的稳定性,6个气象站存在较大的差异。初雷暴日稳定性的排列顺序:湘阴>华容>岳阳>临湘>平江>汨罗。终雷暴日稳定性的排列顺序:平江>湘阴>临湘>岳阳>华容>汨罗。(2)岳阳地区雷暴初日普遍出现在1—3月,2月最多,最早出现在1980年1月1日;岳阳地区雷暴终日普遍出现在9—12月,12月最多,最晚出现在1990年12月29日和1997年12月29日。(3)6个气象站的平均初雷暴日的绝对变率是17.09,终雷暴日的绝对变率是29.92,表明初雷暴日较终雷暴日稳定,年际差异较小。Using thunderstorm day data from six meteorological stations in Yueyang region from 1960 to 2009,the change characteristics of various regions in Yueyang region were analyzed using methods such as absolute variability,climate tendency,and correlation testing.The results show that:⑴There are significant differences in the stability of the initial and final thunderstorm days between the six stations.The order of stability of initial thunderstorm days is:Xiangyin>Huarong>Yueyang>Linxiang>Pingjiang>Miluo.The order of stability of final thunderstorm days is:Pingjiang>Xiangyin>Linxiang>Yueyang>Huarong>Miluo;⑵The first day of thunderstorms in Yueyang area generally occurs from January to March,with the most frequent occurrence in February and the earliest occurrence on January 1,1980;Thunderstorms generally occur throughout the day in Yueyang region from September to December,with the largest number occurring in December,and the latest occurring on December 29,1990 and December 29,1997 The absolute variability of the average initial thunderstorm day at the 6 stations was 17.09,and the absolute variability of the final thunderstorm day was 29.92,indicating that the initial thunderstorm day was stable compared to the final thunderstorm day,with a small interannual difference.
