Physics of Streamers, Leaders, and the Lightning Discharge: High-Resolution Observations and Modeling
Session ID#: 161508
Session Description:
Lightning is comprised of a variety of processes over a multitude of scales including the initial breakdown stage, fast streamer-based breakdown, leader steps, space stems and space leaders, needles from the lateral surface of hot leader cores, recoil leaders, return strokes, and M-components. Lightning channels promote energy exchange between plasma and neutral atmosphere generating reactive chemical species that drive atmospheric chemistry. In recent years, substantial instrumentation advances have been made in optical, radio-frequency, and energetic radiation imaging of the lightning channels' initiation, propagation, and attachment to ground structures, as well as the return stroke and the subsequent processes taking place inside its decaying channels. Additionally, theoretical modeling of streamers, leaders, and the return stroke has evolved to a stage where direct comparisons between model and observations are now possible. We seek abstracts on natural and laboratory observations, modeling, and theoretical efforts dedicated to advancing our communityâs understanding of lightning physics.
