A REVIEW OF THE 2000 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 2000, as reported in the Monthly Global Tropical Cyclone Summaries prepared by the author. (1) Number - this is the cyclone warning 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 JTWC (and PAGASA for Western North Pacific systems in their area of warning responsibility). Greek letter names were assigned to certain systems by the author for purposes of discussion in the monthly summaries. (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. These values are taken from either Japan's or Manila's warnings, whichever had the higher value. 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) ------------------------------------------------------------------------ -- ----- 19-25 May 1012* 30 ATL (1) 01 ----- 07-08 Jun 1008* 25 ATL 02 ----- 23-25 Jun 1008 30 ATL 03 Alberto 03-23 Aug 950 110 ATL 04 ----- 04-11 Aug 1009* 30 ATL -- "Lambda" 11-13 Aug 1006 35 ATL (2) 05 Beryl 13-15 Aug 1007* 45 ATL 06 Chris 17-19 Aug 1008 35 ATL 07 Debby 19-24 Aug 993* 75 ATL -- ----- 28-31 Aug 1005 35 ATL (3) 08 Ernesto 01-03 Sep 1008 35 ATL 09 ----- 08-09 Sep 1009 30 ATL 10 Florence 10-17 Sep 985 70 ATL 11 Gordon 14-21 Sep 981* 70 ATL 12 Helene 15-25 Sep 986 60 ATL 13 Isaac 21 Sep-01 Oct 943 120 ATL 14 Joyce 25 Sep-02 Oct 975 80 ATL 15 Keith 28 Sep-06 Oct 939* 120 ATL -- ----- 30 Sep-04 Oct 987 40 ATL (3) 16 Leslie 04-10 Oct 1003* 40 ATL (4) 17 Michael 15-20 Oct 979* 85 ATL 18 Nadine 19-22 Oct 999 50 ATL -- ----- 25-29 Oct 978 55 ATL (5) NOTES: (1) Information on this system was supplied by Michael Pitt and David Roth. David classified this system as a subtropical depression. (2) This system was included in the August summary based on a Dvorak rating of T2.0 from SAB and a peripheral ship report of 35 kts which suggested that it might be given some consideration for later inclusion as a tropical depression or storm. However, it now appears unlikely that this system will qualify as an unnamed tropical storm. (3) These systems had some hybrid characteristics and could possibly be added to the Best Track file as subtropical storms pending a complete review of all available data. Tracks upon which the above information was based were supplied by David Roth. (4) Before being upgraded to TS Leslie, operational advisories were issued on this system as Subtropical Depression #1. (5) This storm system was treated operationally as a non-tropical storm, but has since been officially reclassified as a subtropical storm and will be added to the Best Tracks database. ************************************************************************ NORTHEAST PACIFIC BASIN NUM NAME DATES CENT PRS MSW BASIN (mb) (kts) ------------------------------------------------------------------------ 01E Aletta 22-28 May 970 90 NEP 02E Bud 13-17 Jun 994 45 NEP 03E Carlotta 18-25 Jun 932 135 NEP 04E ----- 06-07 Jul 1007 25 NEP 01C Upana/Chanchu 20-30 Jul 994 40 (1) NEP/NWP 05E ----- 22-23 Jul 1005 30 NEP 06E Daniel 23 Jul-05 Aug 954 110 NEP 07E Emilia 26-30 Jul 994 55 NEP 08E Fabio 03-08 Aug 1000 45 NEP 09E Gilma 05-11 Aug 984 70 NEP 10E Hector 10-16 Aug 983 70 NEP 11E Ileana 13-17 Aug 991 60 NEP 16W Wene 15-17 Aug 1002 45 (2) NWP/NEP --- "Mu" 26 Aug-02 Sep --- 40 NEP (3) 12E John 28 Aug-01 Sep 994 60 NEP 13E Kristy 31 Aug-03 Sep 1004 35 NEP 14E Lane 05-14 Sep 967 85 NEP 15E Miriam 15-17 Sep 1004 35 NEP 16E Norman 20-22 Sep 998 45 NEP 17E Olivia 02-10 Oct 994 55 NEP 18E Paul 25-29 Oct 1003 40 NEP 19E Rosa 03-08 Nov 993 55 NEP NOTES: (1) TS Upana weakened in the Central Pacific and warnings were dropped by CPHC. The remnant disturbance eventually moved across the Date- line into the NWP where it re-intensified. JTWC referred to the system as 12W and it was named TS Chanchu (0007) by JMA. The highest 10-min avg winds assigned by JMA were 35 kts. (2) System formed just west of (practically straddling) the Dateline and was numbered 16W by JTWC. By the time the second warning was issued the center was just east of the Dateline and remained in the NEP basin for the remainder of its life. (3) No warnings were issued on this system by CPHC. Its inclusion here is based solely upon information supplied by Mark Lander. ************************************************************************ NORTHWEST PACIFIC BASIN JTWC NAME(S) JMA DATES CENT MSW MSW BASIN NUM TROP STM PRS 1-MIN 10-MIN NUM (mb) (kts) (kts) ------------------------------------------------------------------------ 01W Damrey/Asiang 0001 05-12 May 930 155 90 NWP 02W Longwang/Biring 0002 17-20 May 992 40 45 NWP 03W Konsing ---- 20-22 May 1002 30 30 NWP 04W ----- ---- 30 May-01 Jun --- 30 -- NWP --- "Kappa" 01-05 Jul --- 40 -- NWP (1) 05W Kirogi/Ditang 0003 02-08 Jul 940 115 90 NWP 06W Kai-tak/Edeng 0004 03-11 Jul 960 75 75 NWP 07W Gloring ---- 11-15 Jul 1000 25 30 NWP 08W ----- ---- 16-17 Jul 996 25 30 NWP 09W Tembin 0005 17-23 Jul 992 45 40 NWP 10W Bolaven/Huaning 0006 20-31 Jul 980 50 55 NWP (2) 13W Jelawat 0008 30 Jul-11 Aug 940 125 85 NWP (3) 14W ----- ---- 06-12 Aug 1012 30 30 NWP (4) 15W Ewiniar 0009 09-19 Aug 965 75 70 NWP 17W ----- ---- 17-19 Aug --- 25 -- NWP 18W Bilis/Isang 0010 18-24 Aug 915 140 110 NWP --- ----- ---- 19-20 Aug 1000 -- 30 NWP (5) 19W Kaemi 0011 20-23 Aug 985 45 45 NWP 20W Prapiroon/ (6) 0012 25 Aug-01 Sep 965 75 70 NWP 21W Maria 0013 28 Aug-01 Sep 985 55 40 NWP 22W Saomai/Osang 0014 02-18 Sep 925 140 100 NWP 23W Wukong/Maring 0016 02-10 Sep 955 95 75 NWP 24W Bopha/Ningning 0015 05-12 Sep 985 55 50 NWP --- "Nu" ---- 13-18 Sep --- 45 -- NWP (1) 25W Sonamu 0017 14-21 Sep 975 75 55 NWP 26W Shanshan 0018 17-27 Sep 930 135 95 NWP 27W ----- ---- 28-30 Sep 1008 35 30 NWP 28W ----- ---- 06-14 Oct 998 40 30 NWP --- "Xi" ---- 15-19 Oct --- 40 -- NWP (1) 29W Yagi/Paring 0019 21-28 Oct 975 105 65 NWP 30W Xangsane/Reming 0020 25 Oct-02 Nov 965 90 75 NWP 31W Bebinca/Seniang 0021 31 Oct-08 Nov 970 90 70 NWP 32W ----- ---- 08-09 Nov 1004 30 30 NWP 33W Rumbia/Toyang 0022 27 Nov-08 Dec 985 55 55 NWP --- Ulpiang ---- 06-08 Dec --- -- 30 NWP (7) 34W Soulik/Welpring 0023 28 Dec-05 Jan 945 115 80 NWP NOTES: (1) No warnings were issued on these systems by any warning agency. Their inclusion here is based solely upon information supplied by Mark Lander. (2) At one point this system weakened and warnings were dropped by JTWC. When re-intensification occurred, JTWC applied the number 11W to the rejuvenated depression which was later named TS Bolaven by JMA. PAGASA, on the other hand, had named the system Huaning during the period it was being referred to as TD-10W by JTWC, and maintained bulletins on the system during the time JTWC was not issuing warnings. (3) Mark Lander provided me with an alternate track for the first part of Jelawat's history and assessed the peak 1-min MSW at 130 kts. (4) Mark Lander provided me with an alternate track of TD-14W in which he assigned a peak 1-min MSW of 50 kts. (5) This system was carried as a tropical depression by JMA only. (6) The PAGASA name assigned to this system was Lusing. (7) PAGASA was the only agency issuing warnings on this system. ************************************************************************ NORTH INDIAN OCEAN BASIN NUM NAME DATES CENT PRS MSW BASIN (mb) (kts) ------------------------------------------------------------------------ --- ----- 27-30 Mar --- 30 NIO --- "Iota" 25 Mar-01 Apr --- 60 NIO (1) --- ----- 22-23 Aug --- 25 NIO (2) 01B ----- 15-18 Oct --- 35 NIO 02B ----- 26-28 Oct --- 35 NIO 03B ----- 26 Nov-06 Dec --- 65 NIO 04B ----- 25-28 Dec --- 65 NIO NOTES: (1) This is really another and more extended version of the first disturbance listed based upon information supplied by Roger Edson. In Roger's opinion, after the initial disturbance had weakened, a small, rather intense tropical cyclone rapidly spun up and made landfall in southeastern India. (See the March summary for more information on this possible unrecorded tropical storm.) (2) This system was a weak depression classified by IMD only. No track was given in the cyclone tracks file for August, but some information on the system can be found in the monthly summary for August. ************************************************************************ Prepared by Gary Padgett garyp@alaweb.com Home: 334-222-5327 Work: 850-882-2594 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ 05.17.01 / Typhoon2000.com
