A terrifying dust devil ripped through a charred field in Thailand.

Footage shows the vortex whipping up dried grass from the scorched field in the Wichian Buri district of Phetchabun province on April 6.

The twister turned black as it picked up burnt dust and soil before crossing onto the road.

Dust devil tornadoes are types of whirlwinds that form when the sun heats a patch of land and the air above becomes warmer and rises quickly.

Cooler air then moves into the low-pressure gap left by the rising warm air. The new drafts of cooler air also heat up and rise and the cycle continues, picking up dust and debris and making the spiral visible.

They are not as dangerous as supercell tornadoes, which can cause severe damage.
