Northern Hemisphere 2004 Tropical Cyclone Season Review
[Summaries and Track Data] [Prepared by Gary Padgett]


               A REVIEW OF THE 2004 TROPICAL CYCLONE SEASON

                       FOR THE NORTHERN HEMISPHERE


     Following is a tabular summary of all the tropical depressions,
  tropical storms, hurricanes, and typhoons which occurred in the
  Northern Hemisphere between 1 January and 31 December 2004, as
  reported in the Monthly Global Tropical Cyclone Summaries prepared
  by the author.

    (1) Number - this is the sequential cyclone number assigned by either
                 TPC/NHC, CPHC in Honolulu, or JTWC.  If neither of these
                 agencies issued any warnings, no number will be given.

    (2) Name - the name (if any) assigned by either TPC/NHC, CPHC, or
               JMA (and PAGASA for Western North Pacific systems in 
               their area of warning responsibility).

    (3) Dates - range of dates for which tracking information for the 
                cyclone is available in the Global Tropical Cyclone
                Tracks files prepared by the author.

    (4) Pressure - Lowest central pressure (either estimated or recorded)
                   during the lifetime of the cyclone.  For Atlantic and
                   Northeastern Pacific systems these will be the values
                   reported in operational advisories from TPC/NHC or
                   CPHC.  For Northwest Pacific systems the central
                   pressure estimates are taken from advisories issued by
                   the Japanese Meteorological Agency.  An asterisk (*)
                   following the pressure indicates the reading was an
                   actual measured pressure normally obtained by a drop-
                   sonde released during an aerial reconnaissance
                   flight.    Central pressure is given in millibars,
                   which is numerically equivalent to hectopascals.

    (5) MSW - maximum 1-minute average sustained windspeed in knots.
              For the Northwestern Pacific and North Indian Ocean
              basins, these will be the highest value assigned
              operationally by JTWC.  For the Atlantic and Northeastern
              Pacific basins, the MSW values are taken from the
              official tropical cyclone reports prepared by the
              TPC/NHC Hurricane Specialists and which are available
              on TPC/NHC's website: http://www.nhc.noaa.gov> .

    (6) Basins - tropical cyclone basins where the cyclone tracked during
                 its life:

                 ATL - North Atlantic, Gulf of Mexico, Caribbean Sea
                 NEP - North Pacific east of Longitude 180
                 NWP - North Pacific west of Longitude 180
                       (including South China Sea)
                 NIO - Bay of Bengal and Arabian Sea

     For tropical systems in the NWP basin, two additional columns of
  information are given:

     (1) The tropical storm serial number assigned by the Japanese
         Meteorological Agency to tropical depressions which are deemed
         to have reached tropical storm intensity.  This does not always
         agree with JTWC's assessment.

     (2) An estimate of the maximum 10-minute average sustained wind.
         The value given represents the highest 10-min avg MSW assigned
         by any agency.  If from any warning center other than JMA, a
         numbered note below identifies which center's value is given.

     For tropical systems in the NIO basin, a column is given referencing
  IMD's identifier for cyclonic storms:  ARB for Arabian Sea cyclones and
  BOB for Bay of Bengal systems.

     A number in parentheses (e.g. (1) ) following an entry refers to
  a note following the entries for the given basin.   A separate table
  is given for each of the four Northern Hemisphere basins.

 NOTES:

 (1) System was a subtropical storm which never developed full tropical
     cyclone characteristics.

 (2) System was initially a subtropical storm which evolved into a tropical
     storm.  The peak winds of 45 kts occurred during the subtropical storm
     stage--the highest MSW after transforming into a tropical storm was
     40 kts.

 NOTES:

 (1) Classified as a tropical storm by JTWC only.

 (2) The highest 10-min avg MSW was assigned by PAGASA. 

 (3) The highest 10-min avg MSW was assigned by HKO.

 (4) The highest 10-min avg MSW was assigned by HKO and NMCC.

 (5) The highest 10-min avg MSW was assigned by NMCC.

 (6) NMCC was the only agency to classify this system as a tropical
     storm.

 (7) Classified as a tropical depression by JMA only.

 (8) The highest 10-min avg MSW was assigned by the CWB of Taiwan.

 NOTES:

 (1) Onil was quite likely more intense than indicated in the warnings
     from JTWC.  SAB ranked the cyclone at T3.5/3.5 (55 kts) on 1 and
     2 October.

 (2) This system was treated as a depression by IMD.  No track was
     available for inclusion in the Global Tropical Cyclone Tracks
     File for October; however, a short report can be found in the
     October monthly summary.
