Our knowledge and understanding of thunderstorm electrification, lightning breakdown, and the connections of each to the underlying meteorology have increased rapidly in recent years. New instrumentation such as the space-borne Geostationary Lightning Mapper and the growth of ground-based systems such as interferometers, Lightning Mapping Arrays, long-range lightning detection, and high-speed video provide critical new information concerning lightning physics and storm electrification. In many cases, these instruments provide continuous observations lasting throughout a storm's life with high spatial and temporal resolution. Additionally, computational advances have enabled new approaches to forecasting lightning, new methods for lightning assimilation into weather prediction models, and better climatological representations of lightning activity. Knowledge gained from new instrumentation, data analysis, and modeling continues to develop the understanding between lightning physics and the storm properties that affect electrification processes and lightning activity. This session invites abstracts, for oral, poster, or eLightning format, in any of these themes.
