Northern Hemisphere 1998 Tropical Cyclone Season Review
[Summaries and Track Data] [Prepared by Gary Padgett]

               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.

 (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.

       flights into Hurricane Lester, but this was before the storm's
       most intense phase, as adjudged from satellite imagery.

 (1) The 10-min MSW of 85 kts was recorded in Japan at the point where
     Vicki made landfall south of Osaka.

 (2) The 1-min MSW of 40 kts was recorded on Rota as the very small
     center passed by the island.

 (3) The 927.9 mb pressure was recorded at Virac on Catanduanes Island.

 (4) The remnants of Tropical Storm Chip crossed over the Malay Peninsula
    and redeveloped in the Bay of Bengal, becoming Tropical Cyclone 07B.

 (1) These depressions were not classified by JTWC.    The MSW were
     inferred from comments in the daily Tropical Weather Outlooks
     from the Indian Meteorological Department.

 (2) This cyclone was a redevelopment of Tropical Storm Chip which had
     formed in the South China Sea (NWP Basin) and moved across the
     Malay Peninsula.
