Northern Hemisphere 2001 Tropical Cyclone Season Review
[Summaries and Track Data] [Prepared by Gary Padgett]

                A REVIEW OF THE 2001 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 2001, 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 files
        prepared by the author.

    (4) Pressure - Lowest central pressure (either estimated or recorded)
        during the lifetime of the cyclone.  For Atlantic and North-
        eastern 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
        warnings issued by the Japanese Meteorological Agency.    An
        asterisk (*) following the pressure indicates the reading was an
        actual measured pressure normally obtained by a dropsonde
        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 following the table 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) Systems were hybrid-type systems which David Roth felt were possibly
     subtropical storms.  Track and intensity information were provided
     to the author by David.   The minimum central pressure and maximum
     sustained winds given in the table were obtained from actual ship
     observations and not through satellite analysis.

 (2) This system was a tropical wave which was accompanied by a broad
     LOW.  NHC chose not to classify it as a depression--the track and
     intensity were sent to the author by Roger Edson who felt that it
     did qualify as a tropical depression.

 (3) The remnants of this depression moved into the Eastern North Pacific
     and were instrumental in the development of Hurricane Juliette.

 (4) Initially identified operationally as Subtropical Storm #1.

 (5) The official post-storm "best track" identifies the earlier portion
     of Noel's track as a subtropical storm; however, the system was not
     classified operationally as a subtropical storm.

 (6) Initially identified operationally as Subtropical Storm #2.

 (7) Minimum central pressure occurred as Gabrielle was on the verge of
     becoming extratropical.  The minimum pressure at the time of peak
     intensity was estimated at 983 mb.   This was also the central
     pressure at the time of landfall near Venice, FL.

 NOTES:

 (1) System was a classic subtropical Kona LOW north of the Hawaiian
     Islands.  Track was provided by David Roth of HPC.

 (2) Juliette developed from the remnants of Atlantic TD-09.

 (3) Manuel's development was enhanced by the remnants of Atlantic
     Hurricane Iris.

 NOTES:

 (1) No warnings were issued on this system by any warning agency.  Track
     and intensity information were provided to the author by Roger
     Edgon.

 (2) PAGASA was the only agency to issue warnings on these depressions.
     Roger Edson also sent tracks for these systems to the author.
                                                    
 (3) The highest 10-min avg MSW was assigned by NMCC.

 (4) Carried as a tropical depression by JTWC only.

 (5) Carried as a tropical depression by JMA only.

 (6) The highest 10-min avg MSW was assigned by HKO.

 (7) Not treated as a tropical depression by JTWC but was by JMA and
     NMCC.

 (8) Roger Edson also sent the author tracking and intensity information
     for this system.  Roger feels that the system was a tropical storm 
     with winds peaking at 50 kts.

 (9) These systems were not carried as tropical depressions by JTWC but
     were by JMA and some of the other warning agencies.  Roger Edson
     also sent the author tracks and intensities for these systems.  The
     1-min avg MSW values are Roger's estimates.

 (A) JTWC and PAGASA both classified this system as a tropical storm, but
     no other warning center did so.

 (B) JTWC was the only warning center to classify this system as a
     tropical storm.

 (C) PAGASA estimated 10-min avg winds as high as 45 kts for this storm.

 (D) Vamei's typhoon intensity was well-attested to by some ship
     observations which apparently were available to JTWC but not
     to other centers; hence, JMA's intensity estimates were unusally
     far below JTWC's and the corresponding central pressure estimates
     well above 1000 mb.  For this reason I did not include any central
     pressure values in the cyclone tracks file.   The remnants of Vamei
     redeveloped briefly in the North Indian Ocean basin where they
     were identified as TC-05B by JTWC.
