What are dust devils

These columns of brown, dust-filled air, which can rise dozens of feet, are not as evil as the name suggests. They are caused by warm air rising on dry, clear days. Winds associated with dust devils can reach up to 60 miles [96.5 kilometers] per hour and cause some damage, but they are not as destructive as tornadoes and usually die out pretty quickly.
