A REVIEW OF THE 2006 TROPICAL CYCLONE SEASON FOR THE NORTHERN HEMISPHERE Following is a tabular summary of all the tropical depressions, tropical storms, hurricanes, and typhoons which occurred in the Northern Hemisphere between 1 January and 31 December 2006, as reported in the Monthly Global Tropical Cyclone Summaries prepared by the author. (1) Number - this is the sequential cyclone number assigned by either TPC/NHC, CPHC in Honolulu, or JTWC. If neither of these agencies issued any warnings, no number will be given. (2) Name - the name (if any) assigned by either TPC/NHC, CPHC, IMD, or JMA (and PAGASA for Western North Pacific systems in their area of warning responsibility). (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. (4) Pressure - Lowest central pressure (either estimated or recorded) during the lifetime of the cyclone. For Atlantic and Northeastern Pacific systems these will be the values reported in operational advisories from TPC/NHC or CPHC. For Northwest Pacific systems the central pressure estimates are taken from advisories issued by the Japanese Meteorological Agency. An asterisk (*) following the pressure indicates the reading was an actual measured pressure normally obtained by a drop- sonde released during an aerial reconnaissance flight. Central pressure is given in millibars, which is numerically equivalent to hectopascals. (5) MSW - maximum 1-minute average sustained windspeed in knots. For the Northwestern Pacific and North Indian Ocean basins, these will be the highest value assigned operationally by JTWC. For the Atlantic and Northeastern Pacific basins, the MSW values are taken from the official tropical cyclone reports prepared by the TPC/NHC Hurricane Specialists and which are available on TPC/NHC's website: . (6) Basins - tropical cyclone basins where the cyclone tracked during its life: ATL - North Atlantic, Gulf of Mexico, Caribbean Sea NEP - North Pacific east of Longitude 180 NWP - North Pacific west of Longitude 180 (including South China Sea) NIO - Bay of Bengal and Arabian Sea For tropical systems in the NWP basin, two additional columns of information are given: (1) The tropical storm serial number assigned by the Japanese Meteorological Agency to tropical depressions which are deemed to have reached tropical storm intensity. This does not always agree with JTWC's assessment. (2) An estimate of the maximum 10-minute average sustained wind. The value given represents the highest 10-min avg MSW assigned by any agency. If from any warning center other than JMA, a numbered note below identifies which center's value is given. For tropical systems in the NIO basin, an additional column lists the alphanumeric storm identifier assigned by the India Meteorological Department (IMD) for those systems deemed to have reached cyclonic storm (i.e., tropical storm) status by that agency. 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 Northern Hemisphere basins. ========================================================================= ATLANTIC BASIN NUM NAME DATES CENT PRS MSW BASIN (mb) (kts) ------------------------------------------------------------------------ 01 Alberto 10-19 Jun 995 * 60 ATL 02 ----- 16-19 Jul 998 45 ATL (1) 03 Beryl 18-22 Jul 1001 * 50 ATL 04 Chris 01-06 Aug 1001 * 55 ATL 05 Debby 21-28 Aug 999 45 ATL 06 Ernesto 24 Aug-04 Sep 985 * 65 ATL 07 Florence 03-19 Sep 974 * 80 ATL 08 Gordon 10-24 Sep 955 105 ATL 09 Helene 12-27 Sep 955 * 105 ATL 10 Isaac 27 Sep-03 Oct 985 75 ATL NOTES: (1) This system was added during TPC/NHC's post-season analysis and review. It was not carried operationally as a tropical cyclone. There was no track for this system in the Global Tropical Cyclone Tracks file prepared by the author. ========================================================================= NORTHEAST PACFICIC BASIN NUM NAME DATES CENT PRS MSW BASIN (mb) (kts) ------------------------------------------------------------------------ 01E Aletta 27-31 May 1002 40 NEP 02E ----- 03-05 Jun 1005 30 NEP 03E Bud 11-17 Jul 953 110 NEP 04E Carlotta 12-20 Jul 981 75 NEP 05E Daniel 16-28 Jul 933 130 NEP 06E Emilia 21-31 Jul 990 55 NEP 07E Fabio 31 Jul-05 Aug 1000 45 NEP 08E Gilma 01-05 Aug 1004 35 NEP 09E Hector 15-24 Aug 966 95 NEP 01C Ioke (1) 19 Aug-07 Sep 920 140 NEP/NWP 10E Ileana 21-29 Aug 955 105 NEP 11E John 28 Aug-04 Sep 948 * 115 NEP 12E Kristy 30 Aug-09 Sep 985 70 NEP 13E Lane 13-17 Sep 952 * 110 NEP 14E Miriam 16-21 Sep 999 40 NEP 02C ----- 18-20 Sep 1007 30 NEP 03C ----- 26-28 Sep 1006 (2) 30 NEP/NWP 15E Norman 09-15 Oct 1000 45 NEP 16E Olivia 09-14 Oct 1000 40 NEP 04C ----- 13-14 Oct 1007 30 NEP 17E Paul 21-26 Oct 970 90 NEP 18E ----- 26-29 Oct 1007 30 NEP --- ----- 30 Oct-03 Nov --- 55 NEP (3) 19E Rosa 08-10 Nov 1002 35 NEP 20E ----- 11 Nov 1007 30 NEP 21E Sergio 13-20 Nov 965 95 NEP NOTES: (1) Ioke's JMA tropical storm number after crossing into the Northwest Pacific basin was 0612. (2) The lowest CP of 1006 mb was assigned by JMA after system had moved into the Northwest Pacific basin. (3) This system's NRL invest number was '91C', and it occurred at a rather high latitude in the Central and Eastern North Pacific. The system definitely appeared to be at least subtropical in nature, and very possibly was a tropical cyclone. The intensity is based upon a track prepared by Dr. Karl Hoarau of Cergy-Pontoise University, Paris. ========================================================================= NORTHWEST PACFICIC BASIN JTWC NAME(S) JMA DATES CENT MSW MSW BASIN NUM TROP STM PRS 1-MIN 10-MIN NUM (mb) (kts) (kts) ------------------------------------------------------------------------ --- Agaton ---- 20-27 Jan 1000 -- 30 NWP (1) 01W Basyang ---- 03-13 Mar 1004 35 30 NWP 02W Chanchu/Caloy 0601 08-20 May 930 135 90 NWP 03W Jelawat/Domeng 0602 26-29 Jun 994 45 40 NWP (2) 04W Ewiniar/Ester 0603 29 Jun-12 Jul 920 130 100 NWP 05W Bilis/Florita 0604 08-15 Jul 970 55 65 NWP (3) 06W Kaemi/Glenda 0605 17-26 Jul 955 90 80 NWP 07W Prapiroon/Henry 0606 28 Jul-05 Aug 965 70 70 NWP 08W Saomai/Juan 0608 04-11 Aug 925 140 95 NWP 09W Maria 0607 04-12 Aug 975 65 60 NWP 10W Bopha/Inday 0609 05-11 Aug 985 50 50 NWP 11W Wukong 0610 12-21 Aug 980 50 45 NWP 12W Sonamu/Katring 0611 13-16 Aug 992 45 40 NWP 13W ----- ---- 23-25 Aug 1000 30 25 NWP 14W Shanshan/Luis 0613 09-22 Sep 925 120 100 NWP 15W ----- ---- 12-13 Sep 1004 30 30 NWP 16W Yagi 0614 13-27 Sep 910 140 110 NWP 17W ----- ---- 22-25 Sep 996 35 30 NWP 18W Xangsane/ (4) 0615 25 Sep-02 Oct 950 125 85 NWP 19W Bebinca/Neneng 0616 28 Sep-06 Oct 990 45 45 NWP (1) 20W Rumbia 0617 02-06 Oct 985 35 45 NWP 21W Soulik 0618 08-17 Oct 955 90 75 NWP 22W Cimaron/Paeng 0619 26 Oct-06 Nov 910 155 105 NWP (5) --- ----- ---- 06-09 Nov 1000 50 -- NWP (6) 23W Chebi/Queenie 0620 08-14 Nov 925 125 105 NWP (7) 24W Durian/Reming 0621 25 Nov-07 Dec 915 135 105 NWP 25W Utor/Seniang 0622 06-15 Dec 955 100 80 NWP 26W Trami/Tomas 0623 15-20 Dec 1000 30 35 NWP NOTES: (1) The highest 10-min avg MSW was assigned by PAGASA. (2) PAGASA classified this system as a tropical depression on 24 June, and later that same day upgraded it to tropical storm status. (3) The highest 10-min avg MSW estimated by JMA was 60 kts. PAGASA was the only warning agency (known to the author) who upgraded this system to typhoon status. (4) The PAGASA name for Typhoon Xangsane was Milenyo. (5) The peak 1-min avg MSW of 155 kts was obtained from Dvorak analyses performed by Dr. Karl Hoarau of Cergy-Pontoise University, Paris, and is in agreement with intensity estimates from SAB and AFWA. The highest 1-min avg MSW estimated by JTWC was 140 kts. (6) This system appeared to be subtropical in nature. However, it was assigned some tropical "T" Dvorak classifications by SAB who designated it as '99W'. The peak intensity is based upon QuikScat data. (7) Dr. Karl Hoarau estimated the peak intensity for Chebi/Queenie at 135 kts. I have used JTWC's peak 1-min avg MSW of 125 kts, which is good agreement with SAB's and AFWA's peak Dvorak ratings of T6.5/6.5. ========================================================================= NORTH INDIAN OCEAN BASIN NUM NAME IMD ID (1) DATES CENT PRS MSW BASIN (mb) (kts) ------------------------------------------------------------------------ 01A ----- ------- 13-17 Jan --- 40 NIO 02B Mala BOB0601 24-29 Apr --- 125 NIO 03B ----- ------- 02-04 Jul --- 35 NIO --- ----- ------- 01-05 Aug --- 30 NIO 04A Mukda ARB0601 20-25 Sep --- 60 NIO 05B ----- ------- 28-30 Sep --- 35 NIO --- Ogni BOB0602 28-30 Oct --- 45 NIO NOTES: (1) I have learned that IMD discontinued using the former alphanumeric designators when official naming of tropical cyclones in the NIO basin was initiated in 2004. The IDs listed above are unofficial and will not appear in the future in any summaries, track files, and hemisphere reviews prepared by the author. ************************************************************************* Prepared by Gary Padgett garyp@alaweb.com Home: 334-222-5327
