Determination of Lightning Properties from Single Station Wideband Electric Field Measurements

对佛罗里达州17次雷暴期间闪电电场的模拟磁带记录，将分析各种闪电过程的统计特性。我们将从我们的模拟磁带记录中数字化数据；将特别注意：(1)与持续电流、K过程、M分量、初步击穿和负地闪中的先导有关的微秒级脉冲，(2)负地闪中M分量场变化的形状，(3)可用于预测持续电流存在的地闪特性，(4)对地的正闪；(5)云闪中的微秒级脉冲。闪电模型将根据分析结果进行推导或修改。

Analog tape records of the electric fields of lightning flashes, which occurred during seventeen Florida thunderstorms, will be analyzed for statistical properties of various lightning processes. We will digitize data from our analog tape records; particular attention will be paid to: (1) microsecond-scale pulses associated with continuing current, K-processes, M- components, preliminary breakdown, and leaders in negative ground flashes, (2) the shapes of M-component field changes in negative ground flashes, (3) the characteristics of ground flashes that can be used to predict the presence of continuing current, (4) positive flashes to earth, and (5) microsecond-scale pulses in cloud flashes. Lightning models will be derived or modified based on the results of the analyses.
