Time-correlated high-speed video and electric field change data for 139 natural, negative cloud-to-ground (CG)-lightning flashes reveal 615 return strokes (RSs) and 29 upward-illumination (UI)-type strokes. Among 121 multi-stroke flashes, 56% visibly

Data from fast antennas (FAs) with bandwidth of 16 Hz–2.5 MHz and VHF power sensors (Log-RF) with bandwidth of 186–192 MHz are used to examine negative narrow bipolar events, or NNBEs. The main focus is on low-altitude ( 8.0 km) NNBEs are also ex

This study examines the initiation of two intracloud (IC) and two cloud-to-ground (CG) lightning flashes using electric field change (FA) sensors and VHF (LogRF) sensors located at seven sites near Oxford, Mississippi, USA. For each flash the initiat

In this study 29 initial breakdown pulses (IBPs) from four intracloud (IC) lightning flashes are modeled using data from five or more electric field change (E-change) sites. For each flash the first 5–9 located IBPs are investigated. For each IBP t

The electric field change (E-change) data presented herein provide a complementary view of a known terrestrial gamma ray flash (TGF), namely TGF1 from Cummer et al. [2014]. The main E-change pulse coincident with TGF1 was likely an initial breakdown
