The mechanism of a thunderstorm [PDF]

open access: yesProceedings of the Royal Society of London. Series A, Containing Papers of a Mathematical and Physical Character, 1927
Abstract In 1909 I described a theory of the origin of the electricity in thunderstorms based on the observation that when a drop of water is broken up in the air the water obtains a positive charge while the corresponding negative charge is given to the air.
