Pulses feature analysis in a rocket-triggering lightning

The channel base current,the electrical field of close distance and the optical data of high-speed camera in a rocket-triggered lightning are analyzed base on the Shandong Artificial Triggering Lightning Experiment(SHATLE) in 2009.These three signals coincide with each other very well.All the pulses are counted and their electrical and optical characteristics are summarized.This flash contains a total of 31 pulses and the pulses are classified as four kinds according to their features.The current,electrical field and luminosity parameters of the four kinds of pulses are investigated.Their electrical and optical characteristics are gained and the particularity of the flash is researched.
