. .A. D. Moore, University of
Michigan, Professor Emeritus of Electrical Engineering, and
one of the world’s foremost authorities on
electrostatics, says what could be the big ‘breakthrough’
in knowledge of what causes electrical discharges during thunder
storms.....
.the best explanation yet of the electrical discharges we
hear as thunder and see as lightning...”

. .recent observation by Roger Cheng of the University of

almost certainly has an important bearing on how thunderclouds
become charged to their high voltages....”

from the State University of New York at Albany (Cheng, 1970)
have been studying the freezing of super cooled water drops.
suggestion that this mechanism might be important in the generation
of thunderstorm electricity....”

I believe that separation of liquid droplets, rather than ice splinters, may be a basic process causing electrification during riming of super cooled droplet....”

it could well be that this is one of
the main sources of thunderstorm electrification—
especially since it has been shown that B.J.
Mason’s splintering theory has proven inadequate..,
you have made a most interesting discovery.

9. Dr. C. L. Andrews, Professor of Physics, SUNYA,
-
.....
it is the most beautiful combination of mechanics, thermodynamics,
electricity and magnetism and optics... you have initiated
a field worthy of a few lifetimes of study...

Chairman:
Section of Ice and Snow Crystals, International
Conference on Cloud Physics, 1968 in his keynote paper
at the conference, .... .Cheng (1967) observed many clumped
ice crystals and considered that the clumping was caused by
Coulomb force. The author also observed clumped ice crystals...and
found that the clumping seemed to occur under a microscope
by Coulomb force...”

Vol. 50, No. 5, October, 1972, “......it
is noted.. .that the ice crystals observed were in a state
of growth in which the charge separation could occur within
an ice crystal, as pointed out by Cheng (1967).”
