Lightning Meteorology 1: Electrification and Lightning Activity in Typical Thunderstorms
Other contributors: Tony Mostek, Dan Bikos, Brian Motta, Walt Petersen, Fred Mosher, Sam Beckman and the staff from NSSL.
Lightning Meteorology I examines electrification and cloud-to-ground (CG) lightning activity in typical warm season thunderstorms, both isolated storms and mesoscale convective systems. The broad objective of this teletraining course is to utilize CG lightning data in nowcasting / forecasting these storms.
Specific course objectives are:
to gain a basic understanding of the ice-ice collisional charging mechanism
to know the gross distributions of electrical charge in thunderstorms
to understand how charge distributions control the production of negative and positive CG strikes (-CGs and +CGs
to identify minimum thresholds in radar reflectivity and satellite cloud top temperature associated with CG lightning
to use -CGs and +CGs to monitor storm lifecycle and convective and stratiform precipitation
to integrate lightning data with sounding, satellite and radar data
Training Session Options
