Droplet charging in stratiform clouds
Keri A. Nicoll, R. Giles Harrison
The role of droplet charge in stratiform clouds is one of the least well understood areas in cloud microphysics and is thought to affect cloud radiative and precipitation processes…
Remote sensing of cloud base charge
R Giles Harrison, Keri Nicoll, Karen Aplin
Layer clouds are abundant in the Earth's atmosphere. Such clouds do not become sufficiently strongly charged to generate lightning, but they show weak charging along the upper and…
Measurements of the Atmospheric Electric Field through a Triangular Array and the Long-range Saharan Dust Electrification in Southern Portugal
H. G. Silva, F. Lopes, S. Pereira +4
Atmospheric electric field (AEF) measurements were carried out in three different sites forming a triangular array in Southern Portugal. The campaign was performed during the summe…
Electrical charging of ash in Icelandic volcanic plumes
Karen L Aplin, Isobel M P Houghton, Keri A Nicoll
The existence of volcanic lightning and alteration of the atmospheric potential gradient in the vicinity of near-vent volcanic plumes provides strong evidence for the charging of v…
Triboelectric charging of volcanic ash from the 2011 Grímsvötn eruption
Isobel M. P. Houghton, Karen L. Aplin, Keri A. Nicoll
The plume from the 2011 eruption of Grímsvötn was highly electrically charged, as shown by the considerable lightning activity measured by the UK Met Office's low-frequency lightni…
