Northern Hemisphere 2007 Tropical Cyclone Season Review
[Summaries and Track Data] [Prepared by Gary Padgett]

                A REVIEW OF THE 2007 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 2007, 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, IMD,
               or JMA (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:  .

    (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 subtropical storm which never acquired full tropical
     characteristics.  The max winds/min pressure given above are for
     the subtropical portion of its life only.  The parent extratropical
     cyclone from which Andrea evolved produced winds exceeding hurricane
     force.

 (2) The peak winds during the lifetime of Tropical Storm Erin occurred
     during a brief and very surprising intensification episode over
     Oklahoma hundreds of miles inland and three days after landfall on
     the Texas coast.  NHC has officially not classified this phase of
     Erin's life as a tropical storm, but there are some meteorologists
     who disagree with this assessment.

 (3) Upgraded to a hurricane during post-storm analysis.

 (4) System was initially named as a subtropical storm but made the
     transition into a tropical cyclone.

 (5) Winds reached 75 kts after Noel had become, or at least was in the
     process of becoming, an extratropical cyclone.

 (6) System was a non-tropical LOW south of the Azores that developed
     organized convection.  It looked best on 29 December when satellite
     intensity estimates were 35-40 kts, and may have been a subtropical
     storm that day before merging with a front and weakening on the 30th.
     (Comments from Jack Beven.)  Drifting buoy 62901 reported a pressure
     of 1004.6 mb at 31/0000 UTC very near the low-level center, and an
     ASCAT pass around the same time revealed a few 45-kt wind vectors
     near the swath edge in the northwestern semicircle, where the
     pressure gradient would be tightest due to high pressure centered
     to the northwest.

 NOTES:

 (1) Dr. Karl Hoarau performed his own analysis of Typhoon Man-yi and
     does not believe that it reached 130 kts, but rather peaked at
     125 kts (1-min avg).

 (2) Classified as a tropical depression by JMA only.

 (3) The times of JTWC's and JMA's respective peak intensities do not
     coincide.  When JMA was estimating 65 kts (10-min avg), JTWC's peak
     MSW was 80 kts (1-min avg).  At the time of JTWC's peak 1-min avg
     MSW of 85 kts, JMA's 10-min avg MSW was 60 kts.

 (4) This system was classified as Tropical Storm Hanna well before it was
     officially named Lekima by JMA, by which time it had moved westward
     out of PAGASA's AOR.

 (5) No warnings were issued on TS Haiyan by JTWC.  The 1-min avg MSW
     estimates were sent to the author by Dr. Karl Hoarau.

 (6) No warnings were issued on TS Podul by JTWC.  The 1-min avg MSW
     estimates were sent to the author by Dr. Karl Hoarau.

 (7) The peak 1-min avg MSW of 45 kts was estimated by Dr. Karl Hoarau
     during a time prior to warnings being issued on this system by any
     agency.   The peak operational 1-min avg MSW assigned by JTWC was
     35 kts, concurrent with the peak 10-min avg of 45 kts assigned by
     JMA.

 (8) Dr. Karl Hoarau performed a Dvorak analysis of TY Kajiki and estimates
     the peak 1-min avg MSW at 125 kts.

 (9) The times of JTWC's and JMA's respective peak intensities do not
     coincide.  When JMA was estimating 80 kts (10-min avg), JTWC's peak
     MSW was 90 kts (1-min avg).  At the time of JTWC's peak 1-min avg
     MSW of 95 kts, JMA's 10-min avg MSW was 75 kts.

 (10) While JTWC's peak 1-min avg MSW was only 25 kts, several SAB
      satellite fix bulletins rated the system at T2.0/2.0, suggesting
      that the depression produced 30-kt winds at some point.  JMA never
      referenced this system in their High Seas bulletins, even as a
      low-pressure area.  According to Dr. Karl Hoarau, microwave imagery
      clearly indicated the presence of a LLCC.

 (11) JTWC issued only two warnings on this system, and the highest MSW
      was only 25 kts.   Rather unusual, given that the translational speed
      was 29 kts!  Dr. Karl Hoarau estimates that the MSW peaked at 35 kts,
      and I included that value in the track I prepared.  The Dvorak
      estimates from JTWC's own satellite analyst reached T2.5/2.5 for
      several hours, and one SAB rating reached T3.0/3.0.  There was ample
      evidence from satellite imagery, plus the rapid forward motion, to
      believe that this system was a tropical storm.  JMA never elevated
      the system above weak depression status.

 NOTES:

 (1) This system was not officially named operationally by IMD, who has
     official naming responsibility for the NIO basin.  However, the
     Pakistani Meteorological Service unofficially named the storm Yemyin
     and this name was given wide dissemination by the press.  Later, IMD
     re-analyzed the system to have been of cyclone intensity and made
     the decision to officially let the name Yemyin stand.  The highest
     MSW assigned to Yemyin by JTWC was 50 kts, but based on most Dvorak
     intensity estimates, microwave imagery, and at least one SLP
     observation a few hours after landfall, the storm was likely of
     hurricane intensity when it made landfall in Pakistan.

 (2) Dr. Karl Hoarau believes that Sidr peaked at 140 kts.
