“…As a consequence of these observations, it is generally accepted that Fast Breakdown (FB, encompassing both FPB and FNB) is the source of all NBEs and that it involves the propagation of a system of streamers (Attanasio et al., 2019 ; Cooray et al., 2020 ; Griffiths & Phelps, 1976 ; Luque & Ebert, 2014 ; Phelps, 1974 ). These streamers, possibly initiated by ice hydrometeors (Petersen et al., 2006 , 2015 ), propagate hundreds of meters at a speed of a few times 10 7 m/s (although recently [Liu et al., 2021 ] pointed out that the observations are also compatible with a series of streamer bursts at fixed locations) and intensify the electric field in the starting region. Besides the observations listed above, additional studies also support this conclusion, including the analysis of radio spectra (Liu et al., 2019 ) and space‐based optical observations (Li et al., 2021 ; Soler et al., 2020 ).…”

The physical mechanism of Narrow bipolar events (NBEs) has been studied for decades but it still holds many mysteries. Recent observations indicate that the fast breakdown discharges that produce NBEs sometimes contain a secondary fast breakdown that propagates back in the opposite direction but this has not been fully addressed so far in electromagnetic models. In this study, we investigate fast breakdown using different approaches that employ a Modified Transmission Line with Exponential decay (MTLE) model and propose a new model, named “rebounding MTLE model,” which reproduces the secondary fast breakdown current in NBEs. The model provides new insights into the physics of the fast breakdown mechanism.

Narrow bipolar events (NBEs), sometimes also known as narrow bipolar pulses (NBPs), are impulsive and powerful radio emissions from intracloud discharges characterized by intense very high frequency (VHF) radiation, fast propagation speed and short-duration bipolar sferic waveforms in the Low Frequency band (Smith et al., 1999(Smith et al., , 2002(Smith et al., , 2004. NBEs have received great attention since first discovered in the 1980s (Le Vine, 1980;Willett et al., 1989) but their physical mechanism, possibly related to how lightning is initiated inside thunderstorms, remains poorly understood.Over the past decades, several physical mechanisms have been put forward to describe NBEs. One proposal argued that NBEs are caused by energetic particles from cosmic ray air showers triggering relativistic runaway electron avalanches (RREA), a model known as the relativistic runaway electron avalanches-extensive air showers (RREA-EAS) model or as the Runaway Breakdown (RB)-EAS model (e.g.
