What causes smoke storms?

Question

How do they form, and how do they affect humans and the earth?

Answer 1

Can't say I have ever heard of a smoke storm.  The only way to get smoke is by burning something.  You can get areas of dense smoke if there is a fire in an area of light winds and/or low level inversions, which act to concentrate smoke.

Answer 2

Jesus is how they form.

Answer 3

Dry Lightning when they say its going to rain but all its come is a Lightning Strike right on the Forest with No Rain with 90 MPH Wind Gusts then you got a Wildfire lived in California for a Couple of Years in the "Fire" Season that's how I know.
