Monthly Tropical Cyclone Tracks January 2010
[Summaries and Track Data] [Prepared by Gary Padgett]

 
              GLOBAL TROPICAL CYCLONE TRACKS - JANUARY 2010

          !!!! IMPORTANT -- PLEASE SEE NOTE AT END OF FILE !!!!

  
                   ********** SPECIAL NOTE **********

     I now have some assistants who are helping to prepare the monthly
  tropical cyclone files, and I'd like to thank them for their willing-
  ness to assist me.  Kevin Boyle, of Stoke-on-Trent, UK, will be 
  preparing the tracks for Northwest Pacific basin tropical cyclones 
  during the most active part of the NWP season from July through 
  December.  Kevin has already typed up some of the tracks from the 
  latter part of 2009.

     Michael Bath, of McLeans Ridges, New South Wales, Australia, is now
  preparing the track files for Australian Region and South Pacific
  cyclones during the active months of the Southern Hemisphere season.
  Also, Steve Young has now for a year or more been sending me tracks
  with data for the pre-warning and post-warning stages of tropical 
  cyclones in all basins, prepared primarily from NCEP re-analysis data.  

     A very special thanks is due to Kevin, Michael and Steve for their
  assistance.

NORTHWEST PACIFIC (NWP) - North Pacific Ocean West of Longitude 180


                         Sources of Information
                         ----------------------

     The track coordinates and 1-minute average maximum sustained wind
  values in general were taken from operational warnings issued by the
  Joint Typhoon Warning Center (JTWC) of the U. S. Air Force and Navy,
  located at Pearl Harbor, Hawaii.  The central pressure and 10-minute
  average maximum sustained wind estimates for most systems were obtained
  from warnings issued by the Japanese Meteorological Agency (JMA), which
  is the World Meteorological Organization's Regional Specialised Meteor-
  ological Centre for the basin.  In a few instances, information from
  warnings issued by other Asian warning centers may have been utilized.
  The center position coordinates from JMA and other centers were com-
  pared with those from JTWC and annotations made in the Remarks column
  when the differences in general amounted to 40-50 nm or more.

     Michael V. Padua of Naga City in the Philippines, owner of the
  Typhoon 2000 website, sends me cyclone tracks based upon warnings
  issued by the Japanese Meteorological Agency and the Philippines'
  Atmospheric, Geophysical & Astronomical Services Administration
  (PAGASA).  A special thanks to Michael for his efforts.

SOUTHWEST INDIAN OCEAN (SWI) - South Indian Ocean West of Longitude 90E


                          Sources of Information
                          ----------------------

     The track coordinates as well as the central pressure and 10-minute
  average maximum sustained wind estimates were obtained from warnings
  issued by Meteo France's Tropical Cyclone Warning Centre on Reunion
  Island (MFR), which is the World Meteorological Organization's Regional
  Specialised Meteorological Centre for the basin.  The 1-minute average
  maximum sustained wind estimates were taken from warnings issued by the
  Joint Typhoon Warning Center (JTWC) of the U. S. Air Force and Navy,
  located at Pearl Harbor, Hawaii.  The center position coordinates from
  JTWC were compared with those from MFR and annotations made in the
  Remarks column when the differences in general amounted to 40-50 nm
  or more.

  Note: A tropical LOW from the Australian Region tracked westward into
  the SWI basin and became the Very Intense Tropical Cyclone Edzani.
  Since the system began in Perth's AOR, I have included the track in
  the next section covering the Northwest Australia/Southeast Indian
  Ocean region.

NORTHWEST AUSTRALIA/SOUTHEAST INDIAN OCEAN (AUW) - Longitude 90E to 135E


                          Sources of Information
                          ----------------------

     The track coordinates as well as the central pressure and 10-minute
  average maximum sustained wind estimates were obtained from warnings
  issued by the Tropical Cyclone Warning Centres at Perth, Western
  Australia, and Darwin, Northern Territory.    The 1-minute average
  maximum sustained wind estimates were taken from warnings issued by
  the Joint Typhoon Warning Center (JTWC) of the U. S. Air Force and
  Navy, located at Pearl Harbor, Hawaii.  The center position coordinates
  from JTWC were compared with those from the Australian centres and
  annotations made in the Remarks column when the differences in general
  amounted to 40-50 nm or more.

     For the portion of Tropical Cyclone Edzani's track lying west of
  longitude 90E, the following applies:

     The track coordinates as well as the central pressure and 10-minute
  average maximum sustained wind estimates were obtained from warnings
  issued by Meteo France's Tropical Cyclone Warning Centre on Reunion
  Island (MFR), which is the World Meteorological Organization's Regional
  Specialised Meteorological Centre for the basin.  The 1-minute average
  maximum sustained wind estimates were taken from warnings issued by the

Note: JTWC initially issued their final warning on Edzani at 12/0000 UTC
when the cyclone appeared to have begun extratropical transition.  
However, warnings were re-initiated at 12/1800 UTC after the system
had taken on a more tropical appearance.  Following is a portion of the
remarks from the 12/1800 UTC warning:

RE-DEVELOPED OVER THE LOW-LEVEL CIRCULATION CENTER (LLCC) AND HAS WRAPPED
INTO THE NORTHWEST QUADRANT. THIS IMPROVED ORGANIZATION IS ALSO REFLECTED
IN THE AMSU CROSS-SECTIONS, WHICH SHOW A SLIGHTLY STRENGTHENED MID-LEVEL 
WARM TEMPERATURE ANOMALY.  BOTH THE 12/0454Z AND 12/1717Z ASCAT IMAGES 
AND 850MB VORTICITY PRODUCTS INDICATE A SYMMETRIC, 40-45 KNOT TROPICAL 
SYSTEM.  THE TOTAL PRECIPITABLE WATER PRODUCTS ALSO SHOW A STRENGTHENING,
SYMMETRIC DEEP MOISTURE ENVELOPE. THE LATEST DVORAK ESTIMATES FROM PGTW 
ALSO SUPPORT THE CURRENT INTENSITY OF 45 KNOTS........RE-ANALYSIS 
INDICATES THAT THE SYSTEM BEGAN THE EXTRA-TROPICAL TRANSITION (ETT) 
PROCESS BUT DID NOT COMPLETE ETT AS PREVIOUSLY EXPECTED DUE TO A 
TRANSITORY LOW- TO MID-LEVEL RIDGE, WHICH IS PRODUCING A WEST- 
SOUTHWESTWARD TRACK.  TC-07S HAS MAINTAINED TROPICAL CHARACTERISTICS 
DESPITE THE UPPER-LEVEL LOW OVER THE CENTER AND HAS SLOWLY RE- 
CONSOLIDATED AS THE UPPER-LEVEL SHORTWAVE TROUGH AND ASSOCIATED FRONT 
HAVE SEPARATED AND TRACKED AWAY FROM THE SYSTEM. EARLIER INDICATIONS OF 
COLD-AIR STRATOCUMULUS HAVE SUBSEQUENTLY WEAKENED ALONG THE WESTERN 
SEMI-CIRCLE.  OVERALL, THE PREPONDERANCE OF EVIDENCE SUPPORTS THE 
TROPICAL (WARM CORE) ASSESSMENT AND RE-ISSUANCE OF WARNINGS.

     The track coordinates as well as the central pressure and 10-minute
  average maximum sustained wind estimates were obtained from warnings
  issued by the Tropical Cyclone Warning Centres at Darwin, Northern
  Territory; Brisbane, Queensland; and Port Moresby, Papua New Guinea.
  The 1-minute average maximum sustained wind estimates were taken from
  warnings issued by the Joint Typhoon Warning Center (JTWC) of the U. S.
  Air Force and Navy, located at Pearl Harbor, Hawaii.    The center
  position coordinates from JTWC were compared with those from the
  Australian centres and annotations made in the Remarks column when the
  differences in general amounted to 40-50 nm or more.

              !!!!!!  IMPORTANT NOTE - PLEASE READ  !!!!!!

     To repeat the caveat which is included in the Author's Note
  at the end of the cyclone summaries--the tropical cyclone tracks
  I prepare are based upon the operational warnings/advisories/
  advices/bulletins which are issued by the various tropical cyclone
  warning agencies around the world.   Users of these tracks should
  be aware that they are preliminary and subject to revision during
  post-seasonal analyses of the cyclones by the forecasters and
  analysts at the several warning centers.

     For the Atlantic and Northeast Pacific basins, official tropical
  cyclone reports and "best tracks" can be found at the website of
  the Tropical Prediction Center/National Hurricane Center:

     http://www.nhc.noaa.gov>

     The Joint Typhoon Warning Center's website contains links to their
  Annual Tropical Cyclone Reports which include that agency's "best
  tracks" for tropical cyclones in the Northwest Pacific basin, the
  North Indian Ocean, and the Southern Hemisphere:

  and monthly cyclone track files can be obtained at the following
