AE12A:
Thunderstorm Electrification, Lightning, and General Topics in Atmospheric and Space Electricity II

Submit an Abstract to this Session



Session ID#: 31072

Session Description:
Capabilities for observing and modeling lightning and thunderstorm electrification have improved considerably in recent years. Interferometers, Lightning Mapping Arrays, long-range lightning detection, high-speed video, polarimetric radars, and in situ measurements have provided critical new information concerning lightning physics and the storm properties that affect electrification processes and lightning production. Computational advances have enabled increasingly sophisticated models treating these phenomena. These advances also have led to new lightning climatologies, to new approaches forecasting lightning occurrence, and to new methods for assimilating lightning observations into numerical weather prediction models. This session topic invites abstracts dealing with any of these themes. Abstracts describing the development of related observing technologies and computer algorithms also are invited.
