为了提高电场联网数据的一致性,扩大雷暴监测范围,讨论了海拔对电场数据的影响及联网算法存在的问题,提出了一种大气电场数据的海拔校正方法。采用克里格法对2010年南京地区6~8月的电场数据进行联网实验,结合雷达回波资料,对双单体雷暴过程进行综合分析。结果表明,海拔校正方法能有效地修正电场数据,有助于提高大气电场仪的雷暴监测能力。由于各雷暴发展程度不同,雷暴云电荷结构存在差异,导致雷暴回波强度与电场分布不一致,甚至会出现互换的情况。

To improve the network data consistency and expand the field monitoring scope, the effect of altitude on electric field data and the existing problems in networking algorithm were discussed. An altitude correction method was proposed for atmospheric electric field data and the Kriging method used to networking, and the thunderstorm processes analyzed based on atmospheric electric field data in Nanjing from June to August 2010 , with the double monomer thunderstorm process comprehensively analysed. The results show that the altitude correction method can effectively improve the electric field network, and expand the monitoring scope of the electric field. Due to the dif-ferent levels of development of each thunderstorm, there are different charge structures of thunderstorm, resulting in an inconformity between the thunderstorm echo intensity and the electric field distribution, and the situation may e-ven be interchangeable.
