A REVIEW OF THE 2004 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 2004, 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, 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, a column is given referencing IMD's identifier for cyclonic storms: ARB for Arabian Sea cyclones and BOB for Bay of Bengal systems. 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 Alex 31 Jul-06 Aug 957 * 105 ATL 02 Bonnie 03-14 Aug 1001 * 55 ATL 03 Charley 09-15 Aug 941 * 130 ATL 04 Danielle 13-24 Aug 964 95 ATL 05 Earl 13-15 Aug 1009 * 45 ATL 06 Frances 25 Aug-10 Sep 935 * 125 ATL 07 Gaston 27 Aug-03 Sep 985 * 65 ATL 08 Hermine 27-31 Aug 1002 * 50 ATL 09 Ivan 02-24 Sep 910 * 145 ATL 10 ----- 07-10 Sep 1009 30 ATL 11 Jeanne 13-29 Sep 950 * 105 ATL 12 Karl 16-28 Sep 938 125 ATL 13 Lisa 19 Sep-03 Oct 987 65 ATL 14 Matthew 08-11 Oct 997 * 40 ATL 15 Nicole 10-11 Oct 986 45 ATL (1) 16 Otto 26 Nov-05 Dec 995 45 ATL (2) NOTES: (1) System was a subtropical storm which never developed full tropical cyclone characteristics. (2) System was initially a subtropical storm which evolved into a tropical storm. The peak winds of 45 kts occurred during the subtropical storm stage--the highest MSW after transforming into a tropical storm was 40 kts. ************************************************************************ NORTHEAST PACFICIC BASIN NUM NAME DATES CENT PRS MSW BASIN (mb) (kts) ------------------------------------------------------------------------ 01E Agatha 22-26 May 997 50 NEP 02E ----- 02-05 Jul 1007 30 NEP 01C ----- 05 Jul 1007 25 NEP 03E Blas 12-19 Jul 991 55 NEP 04E Celia 19-26 Jul 981 75 NEP 05E Darby 26 Jul-01 Aug 957 105 NEP 06E ----- 29 Jul-03 Aug 1006 30 NEP 07E Estelle 19-25 Aug 989 60 NEP 08E Frank 23-27 Aug 979 75 NEP 09E ----- 23-28 Aug 1005 30 NEP 10E Georgette 26 Aug-03 Sep 995 55 NEP 11E Howard 30 Aug-10 Sep 943 120 NEP 12E Isis 08-21 Sep 987 65 NEP 13E Javier 10-20 Sep 930 130 NEP 14E Kay 04-07 Oct 1004 40 NEP 15E Lester 11-13 Oct 1000 45 NEP 16E ----- 25-26 Oct 1004 30 NEP ************************************************************************ NORTHWEST PACFICIC BASIN JTWC NAME(S) JMA DATES CENT MSW MSW BASIN NUM TROP STM PRS 1-MIN 10-MIN NUM (mb) (kts) (kts) ------------------------------------------------------------------------ 01W Ambo ---- 11-16 Feb 1000 45 30 NWP (1) 02W Butchoy ---- 16-23 Mar 998 45 45 NWP (2) 03W Sudal/Cosme 0401 03-18 Apr 940 130 95 NWP (3) 04W Nida/Dindo 0402 13-22 May 930 140 110 NWP (4) 05W ----- ---- 14-20 May 1002 35 30 NWP (1) 06W Omais/Enteng 0403 16-23 May 985 65 50 NWP 07W Conson/Frank 0404 04-11 Jun 960 95 80 NWP (5) 08W Chanthu/Gener 0405 07-15 Jun 970 75 65 NWP 09W Dianmu/Helen 0406 12-23 Jun 915 155 130 NWP (5) 10W Mindulle/Igme 0407 23 Jun-05 Jul 940 125 105 NWP (2) 11W Tingting 0408 25 Jun-06 Jul 945 80 85 NWP 12W Kompasu/Julian 0409 13-16 Jul 990 45 45 NWP 13W Namtheun 0410 24 Jul-01 Aug 945 115 100 NWP (5) --- NMCC TS-0411 ---- 26-27 Jul 990 -- 45 NWP (6) 14W Meranti 0412 03-09 Aug 960 90 75 NWP 15W Malou 0411 04-06 Aug 994 30 40 NWP --- ----- ---- 06-07 Aug 1002 -- 30 NWP (7) 16W Rananim/Karen 0413 06-13 Aug 950 90 90 NWP (5) 17W Malakas 0414 10-13 Aug 990 35 45 NWP 18W Megi/Lawin 0415 14-22 Aug 970 65 65 NWP 19W Chaba 0416 18 Aug-03 Sep 910 155 130 NWP (5) 20W Aere/Marce 0417 19-31 Aug 955 85 80 NWP 21W ----- ---- 26-31 Aug 1000 35 30 NWP (1) 22W Songda/Nina 0418 27 Aug-11 Sep 925 * 130 120 NWP (5) 23W Sarika 0419 03-09 Sep 980 60 60 NWP (5) --- NMCC TD04 ---- 08-11 Sep 1002 -- 30 NWP 24W Haima/Ofel 0420 10-14 Sep 996 30 40 NWP --- Pablo ---- 14-18 Sep 1006 -- 30 NWP --- NMCC TD06 ---- 15-16 Sep 1006 -- 30 NWP 25W Meari/Quinta 0421 20 Sep-01 Oct 940 120 100 NWP (5) 26W Ma-on/Rolly 0422 03-10 Oct 920 140 105 NWP (8) 27W Tokage/Siony 0423 12-23 Oct 940 125 100 NWP (5) 28W Nock-ten/Tonyo 0424 14-27 Oct 945 110 90 NWP (5) 29W Muifa/Unding 0425 14-26 Nov 955 115 90 NWP (5) --- Merbok/Violeta 0426 22-23 Nov 998 -- 35 NWP --- Winnie ---- 27-30 Nov 1000 -- 30 NWP 30W Nanmadol/Yoyong 0427 28 Nov-04 Dec 935 130 100 NWP (2) 31W Talas/Zosimo 0428 10-21 Dec 992 45 40 NWP 32W Noru 0429 17-23 Dec 990 55 50 NWP (5) NOTES: (1) Classified as a tropical storm by JTWC only.

No track was available for inclusion in the Global Tropical Cyclone Tracks File for October; however, a short report can be found in the October monthly summary. ************************************************************************ Prepared by Gary Padgett garyp@alaweb.com Home: 334-222-5327
