Southern Hemisphere 2007-2008 Tropical Cyclone Season Review
[Summaries and Track Data] [Prepared by Gary Padgett]


                         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 2007 and 30 June 2008 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

 (1) No warnings were issued by any agency for this system.  JTWC
     rendered one Dvorak rating of T2.5/2.5, but intensity estimates
     from SAB were at T2.5/2.5 for about 24 hours, suggesting that the
     system was as least a strong tropical depression and possibly a
     minimal tropical storm based on a 1-min avg criterion.

 (2) Meteo France issued no warnings on this system.  BoM Perth in real
     time assigned a peak MSW of 30 kts, but in post-storm analysis the
     intensity was upped to 40 kts based upon QuikScat data.  Therefore,
     the system is now officially considered as an unnamed tropical

 (3) JTWC issued no warnings on this system--in the track I prepared I
     obtained the 1-min avg MSW values from the JTWC and SAB satellite
     fix bulletins.

 (4) JTWC's estimated peak 1-min avg MSW of 65 kts was at 19/1800 UTC,
     at which time MFR was reporting 50 kts (10-min avg).  MFR's peak
     10-min avg MSW of 60 kts occurred at 22/0600 UTC, at which time
     JTWC was reporting a 1-min avg MSW of 55 kts.

 (5) The highest 10-min avg MSW assigned by MFR was 60 kts at 27/0600 and
     1200 UTC.  The MFR warning issued at 27/1800 UTC, after the center
     had moved inland in Madagascar, indicated that Fame had briefly
     reached the tropical cyclone stage with winds of 65 kts shortly
     before moving onshore.

 (6) In the JMV file, JTWC has upped Gula's peak 1-min avg MSW to 100 kts.

 (1) TC Lee formed in the Australian Region and moved westward into the
     Southwest Indian Ocean basin, where it was renamed Arial by Mauritius.
     Both BoM Perth and Metro France estimated the peak 10-min avg MSW at
     50 kts.

 (2) BoM Perth forecast peripheral gales for this system, but it was not
     named as it did not meet the structural requirements for a tropical
     cyclone that gales be wrapped around more than 50% of the center for
     at least six hours.

 (3) TC Durga formed north of 10S in the AOR of the Jakarta TCWC, which
     became operational in January, 2008, and was the first cyclone to be
     named by that agency.

 (1) The name Guba was assigned by the TCWC at Port Moresby, Papua New

 (2) This LOW was not a tropical cyclone, but was perhaps at least
     partially a hybrid system.

 (3) System was not a tropical cyclone but rather a vigorous monsoon LOW.

 (4) Brisbane treated this system as a tropical LOW with peripheral gales.
     JTWC issued only two warnings, and the significant deltas between
     JTWC's and Brisbane's center fixes suggest that JTWC was perhaps
     following a different LLCC.

 (1) Dvorak satellite intensity estimates on 1 December reached T2.5/2.5
     from JTWC and T3.0/3.0 from SAB, suggesting that the system was
     possibly a minimal tropical storm based on a 1-min avg MSW criterion.

 (2) Dr. Karl Hoarau estimates that Daman reached a peak 1-min avg MSW of
     130 kts at 1800 UTC 6 December.

 (3) Some peripheral gales associated with this system.

 (4) System was a large, monsoon-gyre circulation with an extensive area
     of peripheral gales at times reaching storm force.  A Brisbane
     bulletin on the 22nd noted that the system was similar to the famous
     June, 1994, storm which destroyed a cruising fleet.

 (5) Dvorak ratings from CPHC and Brisbane reached T3.0/3.0 early on the
     18th.  JTWC's ratings peaked at T2.5/2.5 at 17/2330 UTC and were
     coming down by 18/0530 UTC.  The highest noted from SAB was T2.0/2.0.
     The satellite intensity estimates from CPHC and Brisbane seem to
     support this system being a minimal "10-min avg" tropical cyclone.
     RSMC Nadi did forecast peripheral gales for the system.
