Southern Hemisphere 2006-2007 Tropical Cyclone Season Review [Summaries and Track Data] [Prepared by Gary Padgett] |
A REVIEW OF THE 2006-2007 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 2006 and 30 June 2007 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 ************************************************************************ SOUTHWEST INDIAN OCEAN JTWC NAME DATES CENT MSW MSW BASIN NUM PRS 1-MIN 10-MIN (mb) (kts) (kts) ------------------------------------------------------------------------ --- (MFR-01) 18-23 Oct 1002 30 25 SWI 03S Anita 26 Nov-03 Dec 994 45 35 SWI 05S Bondo 17-26 Dec 915 135 110 SWI --- (MFR-04) 25-28 Dec 1000 -- 25 SWI 06S Clovis 29 Dec-04 Jan 975 65 60 SWI --- (MFR-06) 06-08 Jan 999 30 25 SWI 10S Dora 28 Jan-12 Feb 930 115 100 SWI 13S Enok 06-11 Feb 980 55 60 SWI 14S Favio 12-23 Feb 930 125 100 SWI 15S Gamede 20 Feb-04 Mar 935 105 95 SWI 16S Humba 20-28 Feb 960 70 75 SWI/AUW 19S Indlala 10-17 Mar 935 115 95 SWI --- (MFR-13) 13-17 Mar 1000 30 25 SWI --- ----- 20-21 Mar --- 35 -- SWI (1) 22S Jaya 29 Mar-08 Apr 930 110 105 SWI --- (MFR-15) 09-12 Apr 998 -- 45 SWI (2) NOTES: (1) System was a possible subtropical storm. The tracking information was taken completely from SAB satellite fix bulletins. That agency designated the system as Invest 99S. No TCWC issued warnings on the system. (2) This system was classified as a subtropical storm by MFR. ************************************************************************ NORTHWEST AUSTRALIA / SOUTHEAST INDIAN OCEAN JTWC NAME DATES CENT MSW MSW BASIN NUM PRS 1-MIN 10-MIN (mb) (kts) (kts) ------------------------------------------------------------------------ 07S Isobel 31 Dec-03 Jan 982 40 45 AUW (1) 17S George 26 Feb-10 Mar 910 110 105 AUW/AUE 18S Jacob 05-12 Mar 954 75 75 AUW 20S Kara 24-28 Mar 942 105 105 AUW (2) NOTES: (1) In post-storm analysis, it was determined that Isobel had never completely satisfied the criteria for a tropical cyclone. By the definition used by the BoM warning centres, a system has to have gales wrapped around more than 50% of the center for at least six hours to qualify as a tropical cyclone. (2) Operationally, the highest 10-min avg MSW assigned to Kara by BoM Perth was 85 kts. This was upped to 105 kts during a post-storm review. ************************************************************************ NORTHEAST AUSTRALIA / CORAL SEA JTWC NAME DATES CENT MSW MSW BASIN NUM PRS 1-MIN 10-MIN (mb) (kts) (kts) ------------------------------------------------------------------------ 12P Nelson 31 Jan-07 Feb 980 45 55 AUE --- ----- 05-08 Feb 995 -- 45 AUE (1) --- Odette 26 Feb-07 Mar 990 -- 35 AUE 24P Pierre 16-21 May 992 35 40 AUE NOTES: (1) System was not a tropical cyclone, but rather a monsoon depression. ************************************************************************ SOUTH PACIFIC OCEAN JTWC NAME DATES CENT MSW MSW BASIN NUM PRS 1-MIN 10-MIN (mb) (kts) (kts) ------------------------------------------------------------------------ 01P Xavier 20-28 Oct 930 115 95 SPA 02P Yani 17-27 Nov 960 65 75 SPA/AUE 04P (05F) 29 Nov-04 Dec 997 35 30 SPA --- (06F) 09-17 Jan 1000 -- 30 SPA (1) 08P Zita 17-26 Jan 975 60 60 SPA 09P Arthur 21-28 Jan 975 65 60 SPA 11P (09F) 01-05 Feb 997 35 30 SPA --- (12F) 21-26 Mar 998 30 30 SPA 21P Becky 25-31 Mar 975 70 60 SPA/AUE 23P Cliff 03-06 Apr 980 55 50 SPA NOTES: (1) Some peripheral gales were associated with this system. ************************************************************************ Prepared by Gary Padgett E-mail: [email protected] Home Phone: 334-222-5327
