| 摘 要： | 根据1960～2009年贺州市4个气象站（其中富川为1965～2009年）的观测资料，分析了贺州雷暴发生的气候特征及其时空分布规律的可能影响因素、初终雷暴日地域差异和变化趋势、雷暴与降水及温度的关系。结果显示，贺州市属于多雷区，南部多于北部，且年际变化非常大，50年来累计雷暴日数线性减少趋势明显；初终雷暴日及初终间日数年际间变幅较大；雷暴季分布夏季多冬季少，月分布呈单峰型，多集中在2—9月，以8月最多，12月最少；多年平均月雷暴日数序列与降水及气温呈显著正相关；不稳定因子及单站气象要素的变化等对贺州雷暴预报具有较好的指示意义。

| Abstract: | Based on the observation data in 4 stations of Hezhou during 1960-2009(Fuchuan during 1960-2009),the climate characteristics and the spatial and temporal distribution of the possible influencing factors of thunderstorm,regional differences of the first and last thunderstorm and changing trends,relationship between precipitation and temperature with thunderstorms had been studied.The results showed that the Thunderstorms of Hezhou were more in the south than north and had obvious annual variation,which prese... |
