Observations of stepping mechanisms in a rocket ‐ and ‐ wire triggered lightning flash

[1] We present 10 high‐speed video images that depict the bottom 150 m of a downward‐ negative, dart‐stepped leader in a rocket‐and‐wire triggered flash, recorded at 240 kiloframes per second (4.17 ms frame integration time), along with correlated measurements of the X‐ray emission at 50 m, electric field derivative (dE/dt) at 80 m, and the rocket‐ launch‐tower current beneath the leader. We observed discrete segments of secondary channel that exhibited luminosity above that of the surrounding… CONTINUE READING
