====================== TYPHOON '98 ARCHIVES ====================== A REVIEW OF THE 1998 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 1998, 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). (3) Dates - range of dates for which tracking information for the cyclone is available in the Global Tropical Cyclone Tracks documents 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 Northwestern 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 preliminary seasonal summary released by TPC/NHC at the end of the official Hurricane Season on 30 November. (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) ------------------------------------------------------------------------ 01 Alex 27 Jul-02 Aug 1000 50 ATL 02 Bonnie 19-30 Aug 954* 100 ATL 03 Charley 21-22 Aug 1000* 60 ATL 04 Danielle 24 Aug-05 Sep 960* 90 ATL (1) 05 Earl 31 Aug-08 Sep 985* 85 ATL 06 Frances 08-12 Sep 990* 55 ATL 07 Georges 15-29 Sep 937* 135 ATL 08 Hermine 17-20 Sep 999* 40 ATL 09 Ivan 20-28 Sep 975 80 ATL 10 Jeanne 21 Sep-01 Oct 969 90 ATL 11 Karl 23-29 Sep 970 90 ATL 12 Lisa 05-09 Oct 995 65 ATL (1) 13 Mitch 22 Oct-08 Nov 905* 155 ATL 14 Nicole 24 Nov-02 Dec 979 75 ATL (1) There were some lower pressures for Danielle and Lisa given in advisories, but these were likely after the storm was more or less extratropical. ************************************************************************ NORTHEAST PACIFIC BASIN NUM NAME DATES CENT PRS MSW BASIN (mb) (kts) ------------------------------------------------------------------------ 01E Agatha 11-16 Jun 993 55 NEP 02E ----- 19-22 Jun 1005 30 NEP 03E Blas 22-30 Jun 943 120 NEP 04E Celia 17-21 Jul 997 50 NEP 05E Darby 23 Jul-01 Aug 958 100 NEP 06E Estelle 29 Jul-08 Aug 948 115 NEP 07E Frank 06-10 Aug 1001 35 NEP 08E Georgette 11-17 Aug 960 100 NEP 01C ----- 16-19 Aug 1010 30 NEP 09E Howard 21-29 Aug 932 130 NEP 10E Isis 01-03 Sep 987 65 NEP 11E Javier 07-12 Sep 999 45 NEP 12E ----- 01-03 Oct 1006 30 NEP 13E Kay 13-17 Oct 987 65 NEP 14E Lester 15-26 Oct 965 100 NEP (1) 15E Madeline 16-20 Oct 979* 75 NEP (1) - U.S. Air Force Reserve Hurricane Hunters made some reconnaissance flights into Hurricane Lester, but this was before the storm's most intense phase, as adjudged from satellite imagery. ************************************************************************ 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 Akang ---- 07-11 Jul 1002 30 30 NWP 02W Nichole 9801 08-12 Jul 998 45 35 NWP 03W ----- ---- 24-27 Jul 1004 30 30 NWP 04W Otto/Bising 9802 01-05 Aug 975 65 60 NWP 05W Penny/Klaring 9803 06-11 Aug 985 55 50 NWP 06W Rex/Deling 9804 24 Aug-07 Sep 955 115 75 NWP 07W ----- ---- 01-04 Sep 1002 30 30 NWP 08W Stella 9805 12-18 Sep 970 65 60 NWP 09W ----- ---- 13-14 Sep 998 25 30 NWP 10W Todd/Emang 9806 16-20 Sep 955 120 75 NWP 11W Vicki/Gading 9807 17-25 Sep 960 90 85* NWP (1) 12W ----- ---- 18-19 Sep --- 30 -- NWP 13W Waldo 9808 19-22 Sep 994 40 45 NWP 14W Yanni/Heling 9809 25 Sep-02 Oct 965 80 65 NWP 15W ----- ---- 02-06 Oct 1000 30 30 NWP 16W ----- ---- 05-07 Oct 1008 30 30 NWP 17W ----- ---- 06-07 Oct --- 30 -- NWP 18W Zeb/Iliang 9810 09-19 Oct 900 155 130 NWP 19W Alex ---- 11-12 Oct --- 40* -- NWP (2) 20W Babs/Loleng 9811 14-27 Oct 928* 135 105 NWP (3) 21W Chip 9812 11-15 Nov 994 50 40 NWP (4) 22W Dawn 9813 18-20 Nov 998 40 35 NWP 23W Elvis/Miding 9814 22-26 Nov 992 45 40 NWP 24W Faith/Norming 9815 08-14 Dec 975 90 65 NWP 25W Gil 9816 09-13 Dec 996 35 35 NWP 26W ----- ---- 17-19 Dec --- 25 -- NWP 27W ----- ---- 19-22 Dec --- 30 -- NWP (1) The 10-min MSW of 85 kts was recorded in Japan at the point where Vicki made landfall south of Osaka.
