Southern Hemisphere 2000-2001 Tropical Cyclone Season Review [Summaries and Track Data] [Prepared by Gary Padgett]

             A REVIEW OF THE 2000-2001 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 2000 and 30 June 2001 as reported in the Monthly
  Global Tropical Cyclone Summaries prepared by the author.

    (1) Number - this is the cyclone warning 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
               west of 90E and in the Southwest Pacific east of 160E
               which were unnamed, the alphanumeric designator applied
               by La Reunion (MFR) 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 documents 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 or NPMOC.  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

     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.

 NOTES:

 (1) For the Best Track for Bindu, JTWC's peak 1-min avg MSW has been
     reduced to 100 kts.

 (2) Although outside the Australian region, Perth issued a satellite
     bulletin at 02/1800 UTC, assessing the midget cyclone's intensity
     (10-min mean) at 55 kts.  The initial JTWC warning at the same time
     remarked that the system was extremely compact and could be more
     intense than Dvorak analysis implied.

 (3) System was initially referred to in warnings from Reunion as a
     subtropical depression, but the classification was later changed
     to tropical depression.  The highest 1-min mean MSW reported by
     JTWC was 45 kts; the 65 kts above was taken from an analysis
     performed by Dr. Karl Hoarau of Paris--also, Roger Edson reported
     that QuikScat was indicating 60 kts and he expressed the opinion
     that winds of 65 kts were likely occurring in the system around
     1200 UTC on 21 June.     This tiny system displayed a satellite
     signature very similar to Subtropical Cyclone #13 of April, 2000.
     The maximum winds reported by Reunion operationally for that storm
     were 40 kts, but in the Best Track file were upped to 50 kts; and
     Philippe Caroff, the Chief Forecaster at the Reunion TCWC, stated
     that the system could have been classed as a tropical storm.

 NOTES:

 (1) According to Andrew Burton, a meteorologist at Perth, there was a
     slight doubt as to whether the 60 kts reported at Pardoo was a peak
     wind strength or a 10-min mean.  However, three hours earlier the
     same station had reported 55-kt winds--presumably sustained--with
     a pressure of 984 mb.

 NOTES:

 (1) System was not a tropical cyclone but possibly was some sort of
     hybrid system.

 (2) This system also was not a tropical LOW but more hybrid in nature.
     The maximum 10-min mean winds were recorded at Cape Moreton at
     19/1234 UTC.

 (3) System was a subtropical (hybrid) cyclone but acquired significant
     tropical-like features before moving inland.  The maximum 10-min
     mean wind of 54 kts was recorded by the Evans Head AWS at 0652 UTC
     on 8 March.

 (4) System originated in Brisbane's AOR; Fiji assigned a number after
     the center had crossed 160E.

 NOTES:

 (1) None of these systems were true tropical depressions but rather
     hybrid in nature.  The associated gales were well-removed from the
     center in one or two quadrants.

 (2) For the Best Track for Paula, JTWC's peak 1-min avg MSW has been
     increased to 105 kts.
