Relationship Between Lightning Location and Polarimetric Radar Signatures in an MCS.
The relationship of lightning initiation location relative to storm microphysics and structure depicted by polarimetric radar has been analyzed for a small mesoscale convective system (MCS)that occurred on 19 June 2004 during the Thunderstorm Electrification and Lightning Experiment (TELEX).The majority of lightning was initiated in the convective line near two primary altitude regions (4.5 and 8.5 km MSL).The two- layer nature of the lightning initiation points is consistent with a grossly tripolar charge distribution.The lightning initiation points tended to cluster together in small regions of horizontal extent,co-located with convective cells embedded within the MCS.Comparisons of the lightning initiation locations with polarimetric radar data reveal that lightning often initiated on the edge of hail or graupel regions.
