Slang for a gust front tornado. A small tornado, usually weak and short-lived, that occurs along the gust front of a thunderstorm. Often it is visible only as a debris cloud or dust whirl near the ground. Gustnadoes are not associated with storm-scale rotation (i.e. mesocyclones); they are more likely to be associated visually with a shelf cloud than with a wall cloud.
A small tornado, usually weak and short-lived, that occurs along the gust front of a thunderstorm. Often it is visible only as a debris cloud or dust whirl near the ground. It is not associated with the storm-scale rotation found in severe thunderstorms.
Colloquial expression for a short-lived, shallow, generally weak tornado found along a gust front. Gustnadoes are usually visualized by a rotating dust or debris cloud. See nonsupercell tornado.
A weak, and usually short-lived, tornado that forms along the gust front of a thunderstorm, appearing as a temporary dust whirl or debris cloud.
A Gustnado is a slang term for a type of short-lived, shallow, cyclonic circulation that can form in a severe thunderstorm. While it derives its name from the tornado, it has very little in common with tornadoes structurally.
