To Jeff. With search terms “ball lightning” and “St. Elmos fire” you will find more verification of the internal tree fires being plasma fires. Here are links to scienceamerica.com articles that state St. Elmos fire is PLASMA.
On link above search the terms plasma, and corona discharge on that page article is long.
The new strobe lightning in FL is producing the coronal discharges of plasma.
This wikipedia article confirms the plasma in a naturally occuring corona discharge. St elmo’s fire is coronal discharges. The new fire made of plasma.
Bottom line the corona discharges are plasma based. So very likely so too are the internal tree fires (now the new fire is being called St. Elmos fire or witches fire) are also plasma based. C.Discharges are happening in the air with no metal involved.
Sorry for the redundancy.
Strobe Lightning Is Caused by Radiation Overload on Earth’s Surface.
I walked outside of my house during a light sprinkle of rain. Thunder was about over. Yet I was startled by an eye shock of “strobe lightning”. This is the lightning that doesn’t strike as a rod high in the sky. But rather it travels close to Earth exploding like a tiny bomb. And then producing a flash of strobe with a violet to blue corona discharge.
