Southern Hemisphere 2004-2005 Tropical Cyclone Season Review [Summaries and Track Data] [Prepared by Gary Padgett]

              A REVIEW OF THE 2004-2005 TROPICAL CYCLONE SEASON

                         FOR THE SOUTHERN HEMISPHERE

     Following is a tabular summary of all the tropical depressions
  and tropical cyclones which occurred in the Southern Hemisphere
  between 1 July 2004 and 30 June 2005 as reported in the Monthly
  Global Tropical Cyclone Summaries prepared by the author.

    (1) Number - this is the sequential cyclone number assigned by JTWC
        in Hawaii.

    (2) Name - the name (if any) assigned by the responsible Tropical
        Cyclone Warning Centre.  For systems in the South Indian Ocean
        west of 90E and in the Southwest Pacific east of 160E which were
        unnamed, the alphanumeric designator applied by La Reunion or
        Fiji, respectively, is given in this column.

    (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.  The dates given in most cases refer to
        the time the system was in warning status and generally do not
        include the pre-depression stages of the disturbance.

    (4) Pressure - Lowest central pressure (either estimated or recorded)
        during the lifetime of the cyclone.  An asterisk (*) following
        the pressure indicates the reading was an actual measured
        pressure.   Central pressure is given in millibars, which is
        numerically equivalent to hectopascals.

    (5) MSW 1-min avg - maximum 1-minute average sustained windspeed in 
        knots as assigned by JTWC.  An asterisk (*) following the MSW
        indicates that it was an actual measured value.

    (6) MSW 10-min avg - maximum 10-minute average sustained windspeed
        in knots as assigned by the responsible Tropical Cyclone Warning
        Centre.  An asterisk (*) following the MSW indicates that it was
        an actual measured value.

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

        SWI - Southwest Indian Ocean - West of 90E
        AUW - Northwest Australia/Southeast Indian Ocean - 90E to 135E
        AUE - Northeast Australia/Coral Sea - 135E to 160E
        SPA - South Pacific Ocean - East of 160E
        SAT - South Atlantic Ocean

     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 Southern Hemisphere basins.

     Abbreviations for Tropical Cyclone Warning Centres:

  JTWC -    Joint Typhoon Warning Center, formerly on Guam, now at
            Pearl Harbor, Hawaii
  MFR -     Meteo France Reunion (RSMC La Reunion)
  RSMC -    Regional Specialised Meteorological Centre

 NOTES:

 (1) This system had two lives:  the first as a weak but well-defined
     tropical LOW inland over the Cape York Peninsula.  The latter
     portion occurred over water and peripheral gales were reported,
     but the system did not then have the structure of a true tropical
     cyclone.

 (2) System occurred in Port Moresby's AOR but no warnings were issued by
     that agency.  The CP and MSW reported above were taken from gale
     warnings issued by BoM Brisbane.

 NOTES:

 (1) This system drifted westward in the early days of November into
     Brisbane's AOR.  That warning centre mentioned the LOW in its daily
     tropical weather outlook for several days but gave no coordinates.

 (2) Some peripheral gales were associated with these systems.

 (3) No MSW specified in the Tropical Disturbance Summaries issued by
     RSMC Nadi for these systems.
