摘要
本文利用山东雷暴天气中地面定位系统地闪及气象观测站降水资料,分析该地区雷电时空演变特征及其与降水之间的关系。结果表明:山地及丘陵地区发生的地闪多于平原地区,危害较强的正地闪主要分布于海拔相对较高的山东西南及中南部地区。地闪与降水在空间和时间上都有着较好的对应性;特别是在鲁西南和鲁西北平原地区地闪与降水有着较好的相关性,在这些区域可以利用地闪资料反演雷暴天气中的降水。
In this article, characteristics of the temporal-spatial evolution of lightning and their relationship with precipitation have been analyzed by utilizing CG lightning flash data from the DF and precipitation data from observatories. Results show that more CG lightning flashes occur over mountains and uplands than plains in Shandong. Dangerous positive CG lightning flashes mainly distribute between southwest and middle south that have relatively higher altitude. CG lightning flashes and precipitation correlates with each other in terms of time and space, especially in the southwestern and northwestern plains. Precipitation in these areas can be inverted by using CG lightning flash data.
