| Abstract: | Using the conventional surface weather observation data from1956 to 2010 of Laibin weather station,the characteristics of thunderstorms were statistical analyzed.The results show that its annual thunderstorm days are about 46 ~ 106 days(d).the average number of thunderstorm days of a year are 72.4d.The thunderstorm days are likely occurred in June,July and Aug.,which accounts 57.4% of a whole year.Using wavelet analysis method,it shows the thunderstorm activities have a strong vibration cycle of 9-year. |
