A REVIEW OF THE 2003 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 2003, as
reported in the Monthly Global Tropical Cyclone Summaries prepared
by the author.
(1) Number - this is the sequential cyclone 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 files 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 Northwest 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
official tropical cyclone reports prepared by the
TPC/NHC Hurricane Specialists and which are available
on TPC/NHC's website: <http://www.nhc.noaa.gov> .
(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.
The value given represents the highest 10-min avg MSW assigned
by any agency. If from any warning center other than JMA, a
numbered note below identifies which center's value is given.
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) System was a non-tropical LOW which at one point had some extensive
convection east of the center.
(2) System displayed some organized convection, but was a warm-frontal
hybrid.
(3) System was non-tropical but occasionally made attempts to develop
subtropical characteristics; peak winds taken from ship reports.

NOTES:
(1) The Meteorological Department of Thailand estimated the peak MSW at
60 kts, but I do not know if this is intended as a 1-min or 10-min
average MSW.
(2) Classified as a tropical depression by IMD only.
(3) System originated as a tropical depression in the Gulf of Thailand,
hence the JTWC "W" suffix. The Thai Meteorological Department
estimated the highest winds at 30 kts, presumably a 10-min average.
(4) Minimum pressure value taken from IMD's bulletins.
