Default Rain Static ?

Tom,
May I ask you to consider this?
When a water droplet is formed it is a liquid inside a closed surface.
As the droplet falls it gatheres excess energy/ electrical charges via
friction .
Since the the droplet is a closed circuit it is in equilibrium and any
additional charges or excess charges therefore by law must be attached
to the surface of the closed surface.
When the droplet impacts on anything the closed surface opens and
equilibtium is broken
thus releasing the excess charges in the same way a plate capacitor
arcs when equilibrium is broken. I have not read up on static but the
electrical laws that support the above could adequatly describe static
noise from rain. Now getting to snow static I suppose you would have to
go a different way..

environment and some other environments to believe p-noise exists because
they will not experience p-noise.

If one were to live where it never rains (or it never snows), one would
be disinclined to believe rain (or snow) exists. Many years ago (no, I am
sure I have not told this story before) I was asked by a colleague who lived
in a country south of Miami to tell him about snow. Well, I said, it is a
bit like granisado (flavored, shaved ice) without the flavoring (do not eat
the yellow snow) and heaped up everywhere. He was too polite to indicate
his disbelief.

So, what is your religion?

Warm and fond regards, Mac N8TT

Sounds like you might believe that precipitation
static exists. :-)

Faith is a powerful force for self-delusion.

It never snows around here, but no one disbelieves in snow, Mac.
Cecil's idea of the nature of precipitation static is pretty much
based on what he's made up in his head, and not on measurement and
experimentation. Moreover, he puts words in the mouths of people
who disagree with him, such as the above: if you disagree with him
he'll say you don't _believe_ in p-static, as if it were part of some
ham religion. Actually, it's Cecil's ratiocinations that aren't worth
"believing in." Anyone, even you, can investigate the phenomenon of
p-static with some simple homemade equipment, as I referenced in an
earlier post. Then you can decide for yourself how likely it is that
Cecil's ideas have merit or not.
