Lightning initiation: Strong pulses of VHF radiation accompany preliminary breakdown [PDF]
Scientific Reports, 2018 We analyze lightning initiation process using magnetic field waveforms of preliminary breakdown (PB) pulses observed at time scales of a few tens of microseconds by a broad-band receiver.

Time domain simulations of preliminary breakdown pulses in natural lightning. [PDF]
J Geophys Res Atmos, 2015 Lightning discharge is a complicated process with relevant physical scales spanning many orders of magnitude. In an effort to understand the electrodynamics of lightning and connect physical properties of the channel to observed behavior, we construct a ...

Karakteristik Preliminary Breakdown Petir Downward Leader Sebelum Sambaran Negatif Pertama
Jurnal Nasional Teknik Elektro, 2014 A hundred lightning flash was observed in Padang city, West Sumatera at January until Mei 2013. The lightning that use to analyze is proceeding with preliminary breakdown pulse (PBP) train and followed by first negative return stroke (RS).

Locating Preliminary Breakdown Pulses in Positive Cloud‐to‐Ground Lightning [PDF]
Journal of Geophysical Research: Atmospheres, 2018 This paper provides the first concrete evidence that preliminary breakdown (PB) pulses of either polarity in positive cloud‐to‐ground (+CG) lightning are produced by negative leaders.

Characterization preliminary breakdown in the measured lightning electric fields [PDF]
2014 IEEE 8th International Power Engineering and Optimization Conference (PEOCO2014), 2014 In this study, characterization of measured electric fields due to lightning channel was done. Likewise, previous studies on this case were reviewed and discussed accordingly. Furthermore, preliminary breakdown was done in detail and it was indicated on the real measured electric fields and the results were discussed.

Characteristics of the Preliminary Breakdown in Inverted-polarity Intracloud Lightning Flashes
应用气象学报, 2023 The intracloud (IC) flashes can be classified into normal and inverted-polarity types according to their initial leader propagation directions. Due to the rare occurrence of inverted-polarity IC flashes with downward preliminary breakdown (PB) processes,

Temporal and Spatial Characteristics of Preliminary Breakdown Pulses in Intracloud Lightning Flashes [PDF]
Journal of Geophysical Research: Atmospheres, 2019 We have studied the temporal and spatial characteristics of preliminary breakdown (PB) pulses in 32 normal intracloud flashes recorded by a fast antenna lightning mapping array system called Fast Antenna Lightning Mapping Array.
