This paper by Handel examines spontaneous formation of horizontal space charge layers in clouds, presented at the 2nd International Symposium on Unconventional Plasmas. The research demonstrates through theoretical analysis that cloud structures containing ice crystals and water droplets are inherently unstable and will spontaneously develop multiple horizontal regions of charge separation through the polarization catastrophe mechanism, providing the foundational physics for understanding thunderstorm electrification without requiring pre-existing charge separation or external electric fields.
