Webster's 1913 Dictionary
  1. \Cy"clone\ (s?"kl?n), n. [Gr.????? moving in a circle,
    p. pr. of ?????, fr. ky`klos circle.] (Meteor.)
    A violent storm, often of vast extent, characterized by high
    winds rotating about a calm center of low atmospheric
    pressure. This center moves onward, often with a velocity of
    twenty or thirty miles an hour.
    Note: The atmospheric disturbance usually accompanying a
          cyclone, marked by an onward moving area of high
          pressure, is called an anticyclone.
  2. \Cy"clone\, n.
    1. (Meteor.) In general, a condition of the atmosphere
       characterized by a central area of pressure much lower
       than that of surrounding areas, and a system of winds
       blowing inward and around (clockwise in the southern
       hemisphere and counter-clockwise in the northern); --
       called also a {low-area storm}. It is attended by high
       temperature, moist air, abundant precipitation, and
       clouded sky. The term includes the hurricane, typhoon, and
       tropical storms; it should not be applied to the moderate
       disturbances attending ordinary areas of low pressure nor
       to tornadoes, waterspouts, or ``twisters,'' in which the
       vertical motion is more important than the horizontal.
    2. A tornado. See above, and {Tornado}. [Middle U. S.]
