"THUNDERSTORM ELECTRIFICATION"

  Micro-droplets(+) are generated by the freezing of a super cooled water drop,
which is followed by the ejection of electric charged(-) ice fragments,
by sublimation governed by curvature effect in a state of growth.
(rather than by mechanical fracturing, splintering & collision),
from frosty surface of the frozen drop. (ice pellet).
