摘要:
利用线性回归、突变分析、小波分析等方法分析电白雷暴气候特征。结果表明:近53年来,电白雷暴主要集中在4至9月,其中8月最多,5月和7月的年雷暴日数变化较大;雷暴日数总体呈明显下降趋势,下降速率为6.4d/10a;结合M-K突变和滑动t突变检验,没有确定出雷暴日数的突变年份;雷暴日数存在准4年、8-9年、24年的震荡周期;雷暴日数的气候特征受大环流形势影响较明显,而受当地其它气象要素变化的影响较小。
Abstract:
The climate characteristics of thunderstorm in Dianbai were analyzed by linear regression, mutation analysis and wavelet methods. The results show that:the thunderstorms of past 53 years mainly concentrated in April to September with most in August. And the variation of thunderstorm days in May and July was relatively big; Thunderstorm days appeared a overall downward trend with 6.4d/10a; But the mutation year of thunderstorm days was not got by M-K mutation and sliding t mutation test; there is 4 years, 8 to 9 years, 24 years of turbulence cycle of thunderstorm days; The climate characteristics of thunderstorm days more obviously affected by the big circulation situation than the other meteorological elements.
