| 摘 要： | 利用江苏省1971-2000年全省地面测站的雷暴日记录,采用经验正交分解,分析了江苏省区域的雷暴空间分布特征与时间变化趋势,并用Morlet小波进行了周期分析.结果表明,江苏省雷暴呈逐年振荡减少的趋势;全区域变化一致,在此基础上,本省东南部与西北部的变化反相位;雷暴日变化存在一定的周期.本文对认识江苏省雷暴的规律、江苏省雷暴气候评估有一定的参考价值. |

| Abstract: | By using the observational data of thunderstorm days of sixty stations in Jiangsu Province from 1971 to 2000, the characteristics of the thunderstorms of Jiangsu are studied by means of empirical orthogonal function (EOF) method and the analysis of Morlet wavelet. The results show that the mean annual number of thunderstorm days in whole area of Jiangsu Province has a decreasing trend. The south thunderstorm days variable gradient is greater than the north variable gradient, based on this, the southeast and the northwest have opposite trend. The changing of thunderstorm days has a certain periods. The article helps understand thunderstorm of Jiangsu Province. |
