Whirlwind \Whirl"wind`\, n. [Cf. Icel. hvirfilvindr, Sw.

   and {Wind}, n.]
   1. A violent windstorm of limited extent, as the tornado,
      characterized by an inward spiral motion of the air with
      an upward current in the center; a vortex of air. It
      usually has a rapid progressive motion.

            drowns the villages.                  --Bryant.

   Note: Some meteorologists apply the word whirlwind to the
         larger rotary storm also, such as cyclones.

      whirlwind of hounds and hunters.'' --Macaulay.
