Editing Dust devil (section)

=== Ash devils ===
Hot cinders underneath freshly deposited ash in recently burned areas may sometimes generate numerous dust devils. The lighter weight and the darker color of the ash may create dust devils that are visible hundreds of feet into the air.

Ash devils form similar to dust devils and are often seen on [[Atmospheric instability|unstable]] days in burn scar areas of recent fires.

Coal devils are common at the [[coal town]] of Tsagaan Khad in [[Ömnögovi Province|South Gobi Province]], [[Mongolia]]. They occur when dust devils pick up large amounts of stockpiled coal. Their dark color makes them resemble some tornadoes.
