#576245 — The cosmic start of lightning

The cosmic start of lightning
   http://phys.org/news/2015-07-cosmic-lightning.html

   Even though lightning is a common phenomenon, the exact
   mechanism triggering a lightning discharge remains elusive.
   Scientists at the Dutch national research institute for
   mathematics CWI, the University of Groningen and the
   University of Brussels now published a realistic model
   involving large ice particles and cosmic rays.

   The big picture of lightning is clear: charge separation
   occurs inside a thundercloud and is eventually
   short-circuited by a conductive tube of ionized air.
   However, the electric field inside these clouds is usually
   an order of magnitude too low to create the conductive tube.
   This is why lightning inception is first out of the 'top ten
   questions in lightning research', according to a recent
   review.

Pointy things (trees, lightning rods, etc.) cause a localized increase
in the field which lowers the flashover point.

Ever scotch tape a thumb tack to a Van de Graaff generator?

Why does lightning flash in volcanic eruptions?

  Triboelectric charging of the ash clouds.

Yes, but most lightning is cloud-to-cloud and not cloud-to-ground.

Needless to say, there are no "pointy things" within clouds.

Cloud-to-cloud distances are much shorter than cloud-to-ground.

Ever seen a cloud up close, like 500 feet?

Yes, just about a week ago.

The cloud was fog that formed over a school playground
during the early morning.  (Fog is nothing more than
a very low altitude cloud.)

So what?

There is a reason for the two words, i.e. cloud and fog.

Not all clouds, particularly those in a thunder storm, are puffy little
balls.

Jupiter is the star of lightning.Its the reason it gives off 5% more energy than it gets from the Sun.It revoves so fast.It has a red eye caused by a tornado.It has all the right stuff to create static electricity and good conductor.It also have strong magnetic field.TreBert

"Sad but true" So, Glazier give an encore to Maleki.
