Northern Hemisphere 1999 Tropical Cyclone Season Review
[Summaries and Track Data] [Prepared by Gary Padgett]

               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.

 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.

 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.

 NOTES:

 (1) System was intensifying at landfall and winds likely reached
     40-45 kts shortly before moving inland.

 (2) Treated as a depression by only IMD.

 (3) Treated as a depression by only IMD.  System was strengthening at
     landfall and winds were likely 30 kts as it moved inland.
