| 摘要: |
| 基于贵阳市布设的大气电场仪的数据资料进行了初步应用分析，对数据适用性及不同天气过程中大气电场特征进行了分析并就本地适用的预警方式进行讨论。结果发现：大气电场能够反映云中电荷的基本发展情况，对强对流的出现时间上有一定的提前性；大气电场仪受探测距离及安装环境影响明显，目前比较适用单站的预警原理，多站联网反推电荷结构暂无法开展，但多个单站的跟踪观测能够更全面的体现雷电活动的特征，上游站点的信息对下游的预警可以起到很好的提示作用。 |

| Abstract: |
| Based on the data of the atmospheric electric field instrument set up in Guiyang,a preliminary application analysis is made,including the applicability of the data and the characteristics of atmospheric electric field in different weather processes, the applicable local early warning methods are discussed. The results show that the atmospheric electric field can reflect the basic development of the charge in the cloud, and can advance the occurrence time of the strong convection to a certain extent; The atmospheric electric field instrument is obviously affected by the detection distance and the installation environment, at present, the early-warning principle of single station is more applicable,inversion of charge structure by multi-station cannot be carried out , but tracking observation by more single station can reflect the characteristics of lightning activity more comprehensively, and the information of the upstream site can play a good role in the warning of the downstream. |
