Southern Hemisphere 2009-2010 Tropical Cyclone Season Review [Summaries and Track Data] [Prepared by Gary Padgett] |
A REVIEW OF THE 2009-2010 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 2009 and 30 June 2010 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 five 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) Operationally, JTWC assigned a peak MSW of 115 kts to Anja, but this
was reduced to 105 kts in the working "best track" file.
(2) System was classified as a "subtropical depression".
(3) The major SWI system of January was Tropical Cyclone Edzani, which
began in the Australian Region. For information on this very
intense cyclone, see the section below.
(4) System was classified as a "subtropical depression". The 1-min avg
MSW for Joel were obtained from satellite intensity estimates as
JTWC issued no warnings.
