Characterization of return-stroke currents in rocket-triggered lightning
[1] We present a statistical analysis of the salient characteristics of current waveforms for 206 return strokes in 46 rocket-triggered lightning flashes. The flashes were triggered during a variety of experiments related to the interaction of lightning with power lines that were conducted from 1999 through 2004 at the International Center for Lightning Research and Testing at Camp Blanding, Fl...
متن کاملReturn stroke peak current versus charge transfer in rocket‐triggered lightning
[1] We examined data on 117 return strokes in 31 rocket‐and‐wire‐triggered lightning flashes acquired during experiments conducted from 1999 through 2004 at the International Center for Lightning Research and Testing at Camp Blanding, Florida, in order to compare the peak currents of the lightning return strokes with the corresponding charges transferred during various time intervals within 1 m...
متن کاملClose electric field signatures of dart leader/return stroke sequences in rocket-triggered lightning showing residual fields
[1] Vertical electric field waveforms due to dart leader/return stroke sequences measured on the ground 15 and 30 m from the negative lightning channel are used to examine the so-called residual electric field, the difference between the leader electric field change, and the following return stroke electric field change. At these distances, no residual field is expected if the return stroke neu...
متن کاملObserved one-dimensional return stroke propagation speeds in the bottom 170 m of a rocket-triggered lightning channel
[1] The return-stroke propagation speeds of five strokes from a seven-stroke triggered lightning flash are measured, with a 2 ns sampling interval, using a vertical array of photodiodes. Various methods for determining the reference point to be tracked are explored, and the speed is seen to vary over nearly an order of magnitude depending upon which method is chosen. The speeds are generally in...
