====================== TYPHOON '99 ARCHIVES ====================== A REVIEW OF THE 1999 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 1999, 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 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 Arlene 11-18 Jun 1008* 50 ATL 02 ----- 02-03 Jul 1004* 30 ATL 03 Bret 18-25 Aug 944* 120 ATL 04 Cindy 19-31 Aug 944 120 ATL 05 Dennis 24 Aug-07 Sep 962* 90 ATL 06 Emily 24-28 Aug 1004* 45 ATL 07 ----- 05-07 Sep 1005 30 ATL 08 Floyd 07-17 Sep 921* 135 ATL -- "Delta" 07-11 Sep --- 25 ATL (1) 09 Gert 11-24 Sep 930 130 ATL -- "Epsilon" 13-17 Sep 1005 30 ATL (2) 10 Harvey 19-22 Sep 994* 50 ATL 11 ----- 04-06 Oct 1002* 30 ATL 12 ----- 06-08 Oct 1007 30 ATL 13 Irene 13-21 Oct 958* 95 ATL 14 Jose 17-28 Oct 979* 85 ATL 15 Katrina 28 Oct-01 Nov 999* 35 ATL -- ----- 05-07 Nov 998 30 ATL (3) 16 Lenny 13-21 Nov 933* 135 ATL -- ----- 24 Nov-03 Dec 997 40 ATL (3) NOTES: (1) After a post-season review of available data, it was determined that this system had been quite weak. But in satellite imagery it did display some features which raised the possibility that it could have been a very small midget tropical cyclone of somewhat greater intensity--hence its inclusion in the September summary. (2) This system had more to commend its possible inclusion as an unnamed tropical storm, but after a careful review of available data, it was decided not to include the system as a tropical storm. There were some winds exceeding gale force reported by ships, but these were not near the center when the LOW was best organized. This system will likely be considered as a unnumbered/non-operational tropical depression by TPC/NHC. (3) These two systems were hybrid LOWs which exhibited some subtropical characteristics but which never acquired enough organized central convection to be regarded as tropical cyclones. The gale-force winds reported in the second system were peripheral gales well removed from the central area of the LOW. ************************************************************************ NORTHEAST PACIFIC BASIN NUM NAME DATES CENT PRS MSW BASIN (mb) (kts) ------------------------------------------------------------------------ 01E Adrian 18-22 Jun 975 85 NEP 02E Beatriz 09-16 Jul 956 105 NEP 03E ----- 14-15 Jul 1007 30 NEP 04E ----- 23-25 Jul 1007 30 NEP 05E Calvin 25-27 Jul 1005 35 NEP 06E ----- 26-28 Jul 1005 30 NEP 07E Dora (9911) 06-23 Aug 943 120 NEP/NWP 08E Eugene 06-15 Aug 965 95 NEP 09E ----- 13-15 Aug 1005 30 NEP 10E Fernanda 17-22 Aug 994 55 NEP 11E ----- 23-24 Aug 1000 30 NEP 12E Greg 05-09 Sep 987 65 NEP 13E Hilary 17-21 Sep 987 65 NEP 14E Irwin 08-11 Oct 997 50 NEP NOTE: Hurricane Dora was assigned the number 9911 by the Japanese Meteorological Agency when the storm crossed longitude 180 and entered the Northwest Pacific basin. ************************************************************************ 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 Hilda/Auring ---- 03-08 Jan 1000 35 30 NWP 02W Iris/Bebeng ---- 15-18 Feb --- 35 30 NWP 03W Jacob/Karing ---- 06-10 Apr --- 35 30 NWP 04W Kate/Diding 9901 22-28 Apr 980 75 55 NWP 05W Leo 9902 27 Apr-02 May 960 110 75 NWP 06W Maggie/Etang 9903 01-08 Jun 955 105 85 NWP --- Gening ---- 04-06 Jun --- -- 30 NWP (1) 07W ----- 9904 15-18 Jul 996 30 35 NWP (2) 08W ----- ---- 21-22 Jul --- 30 -- NWP 09W Neil/Helming 9905 21-28 Jul 980 40 50 NWP 10W ---- 9906 26-27 Jul 985 25 40 NWP (2) 11W Olga/Ising 9907 28 Jul-03 Aug 970 75 65 NWP 12W Paul 9908 03-08 Aug 985 50 45 NWP 13W Rachel 9909 05-09 Aug 992 35 35 NWP 14W ----- ---- 08-10 Aug --- 30 -- NWP --- "Alpha" ---- 08-11 Aug --- 55 -- NWP (3) --- "Beta" ---- 09-11 Aug --- 45 -- NWP (3) --- "Gamma" ---- 11-17 Aug --- 35 -- NWP (3) 15W ----- ---- 16-18 Aug --- 25 -- NWP 16W Sam/Luding 9910 18-23 Aug 980 75 55 NWP 17W Tanya 9912 19-24 Aug --- 70 50 NWP (4) 18W ----- ---- 21-24 Aug --- 30 -- NWP (5) 19W Virgil 9913 24-29 Aug --- 75 45 NWP (6) 20W Wendy/Mameng 9914 30 Aug-04 Sep 996 40 40 NWP 21W York/Neneng 9915 10-17 Sep 980 70 55 NWP 22W Zia 9916 13-15 Sep 985 35 45 NWP 23W Ann 9917 15-20 Sep 980 45 50 NWP 24W Bart/Oniang 9918 17-25 Sep 930 140 90 NWP 25W Cam 9919 22-26 Sep 990 40 45 NWP 26W Dan/Pepang 9920 02-11 Oct 960 110 80 NWP 27W Eve/Rening 9921 15-20 Oct 990 45 45 NWP --- "Zeta" ---- 02-05 Nov 1003 20 -- NWP (7) 28W ----- ---- 05-07 Nov 1000 30 30 NWP 29W Frankie/Sendang ---- 06-10 Nov 994 35 40 NWP (8) --- "Eta" ---- 08-16 Nov --- 60 -- NWP (9) 30W Gloria/Trining 9922 13-16 Nov 980 65 50 NWP --- "Theta" ---- 26 Nov-01 Dec --- 50 -- NWP (A) 31W ----- ---- 01-04 Dec --- 30 -- NWP 32W ----- ---- 09-11 Dec --- 30 -- NWP 33W ----- ---- 14-16 Dec --- 30 -- NWP NOTES: (1) System was carried as a tropical depression by PAGASA only. (2) These depressions were classifed as tropical storms by JMA. (3) Tracks and intensities for these systems were provided by Dr. Mark Lander of the University of Guam. Greek letter names were assigned by the author. (4) Mark Lander's highest MSW for Tanya was 90 kts. (5) Mark Lander's highest MSW for 18W was 45 kts. (6) Mark Lander's highest MSW for Virgil was 100 kts. (7) System was a monsoon depression which brought extremely devastating floods to Vietnam. According to Mark Lander, gale-force winds were present in a peripheral cloud band to the north and east of the center, and winds were likely approaching gale force in the central region when landfall occurred. (8) Frankie/Sendang was not regarded as a tropical storm by JMA. (9) Track and intensity for this system provided by Mark Lander. The peak winds of 60 kts occurred after the initial tropical depression had weakened and had transformed into a vigorous subtropical cyclone. Estimated strongest winds while still a tropical depression were 30 kts. (A) Track and intensity for this system provided by Mark Lander. System originated east of Dateline as a typical Hawaiian Kona LOW. Peak winds of 50 kts occurred during this initial subtropical phase. After transforming into a tropical storm the highest MSW were estimated to be on the order of 40-45 kts. ************************************************************************ NORTH INDIAN OCEAN BASIN NUM NAME DATES CENT PRS MSW BASIN (mb) (kts) ------------------------------------------------------------------------ 01B ----- 01-05 Feb --- 40 NIO 02A ----- 16-22 May --- 110 NIO 03B ----- 10-11 Jun --- 35 NIO (1) --- ----- 17 Jun --- 30 NIO (2) --- ----- 27-28 Jul --- 25 NIO (3) --- ----- 06-08 Aug --- 25 NIO (2) 04B ----- 15-19 Oct --- 120 NIO 05B ----- 25 Oct-01 Nov --- 140 NIO --- ----- 08-11 Dec --- 25 NIO (2) NOTES: (1) System was intensifying at landfall and winds likely reached 40-45 kts shortly before moving inland.
