Comparative study on preliminary breakdown pulse trains observed in Malaysia and Florida
2010 30th International Conference on Lightning Protection (ICLP), 2010In this paper, the preliminary breakdown pulse (PBP) trains preceding the negative first return strokes recorded using a broad band antenna system in Johor Bahru, Malaysia and Florida, United States were analyzed. In lightning flashes observed in Malaysia, the ratio between the amplitude of the largest preliminary breakdown pulse (PBP) and the peak ...

PRELIMINARY EVIDENCE FOR SELF-FOCUSING IN GAS BREAKDOWN PRODUCED BY PICOSECOND LASER PULSES
Applied Physics Letters, 1969An investigation of the sparks produced by picosecond pulses from mode-locked Nd:glass and ruby lasers indicates the existence of breakdown regions of diameter less than 5 μ. These results support the hypothesis that self-focusing of the beam may be involved in the breakdown process.

Characteristic pulse trains of preliminary breakdown in four isolated small thunderstorms
Journal of Geophysical Research: Atmospheres, 2017AbstractUsing a low‐frequency six‐station local network, preliminary breakdown (PB) pulses not followed or followed by negative return stroke (RS), which are defined as PB‐type and PB cloud‐to‐ground (PBCG)‐type flashes, are analyzed based on four isolated small thunderstorms for the first time.

2014 International Conference on Lightning Protection (ICLP), 2014
The first stroke leader in a cloud-to-ground lightning discharge is thought to be preceded by the initial or preliminary breakdown process which produces a train of relatively large microsecond-scale electric field pulses. In addition to producing the information used to geolocate various types of lightning events (cloud-to-ground return strokes, M ...

In this paper, the characteristics of electric fields due to preliminary breakdown pulses (PBP) that precede the first return strokes (FRS) are presented. These pulses exist due to the electrical activity formed inside the clouds prior to the occurrence of the stepped leader.
