DUST DEVIL Chases Woman Across Street In Russia...
A dust devil chased a woman across the street in Russia, forcing her walk to become a sprint! Just when she finally thinks she got rid of it, the whirlwind turns on her for a second time. A dust devil is a strong, well-formed, and relatively long-lived whirlwind, ranging from small (half a meter wide and a few meters tall) to large (more than 10 meters wide and more than 1000 meters tall). They are usually harmless, but can on rare occasions grow large enough to pose a threat to both people and property.

They are comparable to tornadoes in that both are a weather phenomenon of a vertically oriented rotating column of air, but that's where it ends. Tornadoes are associated with a larger parent circulation, the mesocyclone on the back of a supercell thunderstorm. Dust devils form as a swirling updraft under sunny conditions during fair weather, rarely coming close to the intensity of a tornado.
