It especially shows up in the 300 inches a year lake effect snowfalls in
northern NY. You can hear it on 6 and 2 quite well. These were DC
grounded yagi antennas on all elements, so no corona available here,
thank you.

What makes you think the charge gradient and corona goes away with a
grounded element? Because there is never lightning and lightning never
hits a grounded object? Where dod you get that idea?

The earth is one terminal, the air and things in the air (like clouds)
have a charge difference.

So this is an inverse form of corona? Where it comes from the
surrounding charged air and particles (whatever type they are)? Because
it's not the form I'm familiar with where the end of the antenna has a
high voltage on it.

I am genuinely asking a question here. If this is the way that noise
occurs, I'd like to know the physical method involved.

It still sounds like it matches the description of what is commonly
called precipitation static, and it still makes a lot of noise, unless
you'd like me to disbelieve my lieing ears.
