摘要:
利用数理统计、小波分析等研究方法对1957-2013年江门市新会区国家基本气象站雷暴日数观测资料进行分析得出：新会为多雷区，近57a平均雷暴日为77.84d，最多117a，最少53a，雷暴日数的年际波动比较明显，呈波动下降趋势，平均每10年减少3.10d；初、终雷日的最早与最晚相差3个多月，初雷日有明显的后延趋势，平均每10a推后1.19d，终雷日趋势变化不大；57a平均雷暴持续期为224d，最长是1972年的317d，最短是1967年和1989年的175d，且持续期略有缩短趋势，平均每10a减少1.23
Abstract:
Based on the analysis of thunderstorm days from 1957 to 2013 of Xinhui national basic meteorological station by the methods of mathematical statistics and the wavelet, the results show that:Xinhui is frequently affected by the thunderstorms, in which the annual average lighting days is 77.84 with maximum of 117 and minimum of 53. The change trend presents obviously fluctuating pattern and the overall fluctuating shows downward trend, declining by 3.10 d every 10 years. The date of the first lightning during the year is earlier than the date of the last one over three, and the date first lightning shows an obvious tendency to delay with 1.19 d every 10 years, but the trend of last lightning is steady. The average duration of the thunderstorm in 57 years is 224d with the longest 317d in 1972 and the shortest 175d in 1967 and 1989. Furthermore, the duration presents a slightly shorter changing pattern with decreasing 1.23 d in every 10 years. There was a mutation caused by dramatic fluctuation of the annual thunderstorm between 1975 and 1976.
