The initiation of lightning in thunderclouds: The possible influence of metastable nitrogen and oxygen molecules in initiating lightning streamers [PDF]

open access: yesJournal of Geophysical Research: Atmospheres, 2015
AbstractAn examination is made of the possible role of metastable molecules of oxygen and nitrogen to contribute to the difference between the observed breakdown field in air of ~25 kV/cm and the electric fields observed in thunderclouds which generally have a maximum of ~3 kV/cm, which suggest much lower breakdown fields.

Lightning Impulse Ageing of HDPE

open access: yes, 2009
This work is concerned with the hypothesis that lightning impulses can lead to accelerated ageing of extruded polymeric cables. The behaviour of an insulation material when suffering lightning impulses is different from that for DC or power frequency ...

Rapid evolution of energetic lightning strokes in Mediterranean winter storms

open access: yesnpj Climate and Atmospheric Science
The occurrence of winter lightning concentrates in a few specific regions in the world, including the Mediterranean, where electromagnetic signatures of this interesting dangerous phenomenon have not yet been studied in detail. We investigate the initial
