Abstract:

Intracloud lightning streamers have been modeled from balloonborne electric field change measurements and acoustic reconstructions of the lightning channel to approximate the streamer path. The simple model assumes the streamers extend along a straight line with constant velocity and uniform line charge concentration. Positive and negative polarity streamers were measured with an average velocity and line charge concentration of 530,000 x 104 msec-1 and 0.0067cm, respectively. A lightning-struck balloon measured field changes associated with the positive propagating streamer that coupled to the conducting balloon skin. The first results of these measurements are presented. The model for this streamer based on the balloon data is incomplete at the time of this writing.
