  Cyclone  \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.] 
 
  From  Webster's  Revised  Unabridged  Dictionary  (1913)  [web1913]: 
 
  Cyclone  \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. 
 
  From  WordNet  r  1.6  [wn]: 
 
  cyclone 
  n  1:  (meteorology)  rapid  inward  circulation  of  air  masses  about  a 
  low-pressure  center;  circling  counterclockwise  in  the 
  northern  hemisphere  and  clockwise  in  the  southern  [ant: 
  {anticyclone}] 
  2:  a  violent  rotating  windstorm
