| Abstract: | Based on the daily thunderstorm data of 10 meteorological stations in Tongliao area from 1971 to 2007 years, time series of thunderstorm days and times were constructed. The thunderstorm characteristics were ana- lyzed in Tongliao area by climate trend analysis and wavelet analysis, which revealed the geographic distribution features, the characteristics of interdecadal variation, interannual variation, monthly variation, diurnal variation , the first thunderstorm day, the last thunderstorm day, the thunderstorm duration and the periodic oscillation, etc were obtained. |
