Tornado plasma hypothesis

The tornado plasma hypothesis is a hypothesis that plasma effects are associated with tornadoes.

Edward Lewis has reported radio emissions that suggest rapid plasma glow discharges (silent "tornado lightning", similar to the plasma filament inside a fluorescent light bulb) on the order of 20 Hz. Lewis has associated tornadoes with plasmoids and point discharges, as well as a host of other plasma effects.

However most other researchers dismiss reports of the plasma effect, and these hypotheses remain outside the mainstream.

Plasma is possibly a factor in the creation of ball lightning.
