采用传输线（TL）和天线理论（AT）模型计算了距离闪电通道基地500 m、5 km和50 km的地面电场，比较了通道基地典型后续冲程电流和等于光速（v = c）的回程冲程速度。AT模型给出的总电场峰值比TL模型预测的电场峰值低10%左右。对闪电通道底部100米内的回程速度的光学测量进行了审查，发现不支持v = c的假设。
Electric fields on the ground 500 m, 5 km, and 50 km from the lightning channel base computed using the transmission line (TL) and antenna theory (AT) return-stroke models for a typical subsequent stroke current at the channel base and a return-stroke speed equal to the speed of light (v = c) are compared. The AT model gives a total electric field peak that is about 10% lower than the field peak predicted by the TL model. Optical measurements of the return-stroke speed within the bottom 100 m of the lightning channel are reviewed and found to be not supporting the assumption of v = c.
