Downburst

  • abstract: A downburst is a strong ground-level wind system that emanates from a single source, blowing in a straight line in all directions from that source. Often producing damaging winds, it may be confused with a tornado, but is actually quite different: In a tornado, high velocity winds circle a central point, moving inward and upward whereas in a downburst, winds are directed downward and then outward from the surface landing point.
