| 摘要: |
| 为实现更准确的雷电监测预警，基于贵州省冰雹防控外场试验基地威宁核心区安装的大气电场仪进行不同天气形势下的大气电场特征研究，并结合雷达进行数据对比分析。结果发现：雷电、冰雹等强对流天气大气电场曲线会出现明显的抖动，稳定性天气大气电场变化趋于平缓；大气电场仪探测较为敏感，受探测距离限制严重，通过雷达回波对比，靠近大气电场仪探测中心的数据更为有效，且电场数据受自身及周边环境影响较大。 |

| Abstract: |
| In order to achieve more accurate lightning monitoring and early warning, the atmospheric electric field instrument installed in the core area of Weining in the Guizhou Province hail prevention and control was used to analyze the atmospheric electric field under different weather conditions, and the data was compared with the radar. The results show that the atmospheric electric field curve of strong convection weather such as lightning and hail will show obvious jitter, and the value of the atmospheric electric field tends to be gentle on stable weather. Atmospheric electric field instrument is sensitive and limited by the detection distance. The data near the detection center is more effective, and the electric field data is greatly affected by itself and the surrounding environment. |
