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.

(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.
