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…

Electrical properties of volcanic ash samples from Eyjafjallajökull and Grímsvötn
I. M. Houghton, K. L. Aplin, K. A. Nicoll
Volcanic ash is known to charge electrically, producing some of the most spectacular displays of lightning in nature. Here we investigate the electrical characteristics of ash from…
