               GLOBAL TROPICAL CYCLONE TRACKS - MARCH 2009

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


                            MARCH HIGHLIGHTS
                            ----------------

  --> Small cyclone forms and nears hurricane intensity in Mozambique
      Channel but doesn't affect land
  --> Intense cyclone forms off Northwestern Australia but tracks out to
      sea
  --> Very intense cyclone threatens Queensland coast but doesn't make
      landfall
  --> Two South Pacific cyclones form east of Dateline


                             GLOBAL OVERVIEW
                             ---------------

     No tropical cyclones formed in the Northern Hemisphere during March,
  but the Southern Hemisphere was very active with seven named systems
  (although one was later downgraded by BoM Perth).  Two systems were
  numbered by MFR.  The first, Tropical Depression 10, formed in the
  eastern stretches of the Southwest Indian Ocean and moved southeast-
  ward.  JTWC briefly upgraded this system to a minimal 35-kt tropical 
  storm.  Late in the month, Severe Tropical Storm Izilda formed in the
  Mozambique Channel and peaked at 60 kts (65 kts 1-min avg per JTWC)
  and threatened Madagascar, but moved erratically and weakened and
  remained in the Channel until it dissipated.

     The Australian Region was quite active with intense cyclones forming
  on both sides of the continent.  A fairly nebulous system was named
  Gabrielle by BoM Perth early in March well off the Western Australian
  coastline, but in post-analysis it was decided that Gabrielle had not
  met the criteria for a tropical cyclone as applied by BoM.  Gales must
  surround more than 50% of the circulation center for at least six 
  hours.  While Gabrielle produced gales over a period of a couple of
  days, the gales existed in only one quadrant at the time; hence, the
  system is now considered a tropical LOW.  Around mid-month, Tropical
  Cyclone Ilsa formed south of Indonesia and eventually became a 90-kt
  intense cyclone (110 kts 1-min avg per JTWC) as it moved harmlessly
  on a west-southwesterly track well out into the Southeast Indian Ocean.

     In the Coral Sea, intense Tropical Cyclone Hamish formed early in
  the month and posed a very serious threat to the Queensland coast.  
  Hamish was the first tropical cyclone in Australian waters to reached
  Category 5 status since Cyclone George in 2007.  BoM Perth estimated
  Hamish's peak 10-min avg intensity at 115 kts, while JTWC's peak 1-min
  avg MSW was 130 kts.  Fortunately, Hamish remained at sea and weakened
  without making landfall.  Two fishermen apparently perished when their
  boat capsized, and serious beach erosion occurred along extensive
  reaches of the Queensland coast.  Also, an oil spill was blamed on
  rough seas generated by the cyclone.

     Around mid-month a weak tropical LOW associated with the remnants
  of Hamish formed but never developed into a tropical cyclone.  A second
  center formed within a large trough and this center produced gales east
  of 160E in Fiji's AOR, although by that time is was likely hybrid in
  character.   The remnants of the initial tropical LOW combined with
  areas in the monsoon trough to form a new LOW center which ultimately
  developed into Tropical Cyclone Jasper.  Jasper moved eastward into
  Nadi's AOR where it soon began to weaken and dissipate.

     Much farther to the east, two tropical cyclones of moderate
  intensity, Joni and Ken, formed east of the Dateline and scooted off
  to the southeast into the wastes of the Southeastern Pacific.

                         ----------------------

     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: I have learned from Joe Courtney of BoM Perth that in post-analysis
it was determined that Gabrielle did not meet the minimum requirements of
a tropical cyclone by the Australian definition, which requires that 
gales extend more than halfway around the center for at least six hours.
Gales were observed in one quadrant or another throughout most of
Gabrielle's life, but at no one time did they extend more than halfway
around the LLCC.   Gabrielle will not be included as a cyclone event in
BoM's Best Tracks file.

Note: During the time this system was in Brisbane's AOR, I reported the
MSW at 25 kts based upon the values given in the technical bulletins,
which were issued as long as it was felt there was a chance of tropical
cyclone genesis.  Fiji also issued a gale warning at 21/0000 UTC, picking
up the easternmost of the two centers and subsequently following this
center.  The 40-kt MSW values from 21/0600 UTC onward are taken from
RSMC Nadi's warnings.  Nadi referred to this system as a 'depression' as
opposed to a 'tropical depression', likely implying hybrid features.
No 'F' number was assigned this LOW by Fiji.

                          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 Nadi, Fiji, and
  Wellington, New Zealand.  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 Southern Hemisphere centres and annotations made in the
  Remarks column when the differences in general amounted to 40-50 nm
  or more.

     Following is the link to the Wikipedia page for the 2008-2009
  South Pacific Cyclone Season.  A special detailed report for Tropical
  Cyclone Joni is available.

                  SOURCES OF TROPICAL CYCLONE INFORMATION

     The purpose of this section is to list some websites where many and
  varied types of tropical cyclone information are archived.  Many readers
  will know about these already, but for the benefit of those who don't,
  I wanted to include them. 

  (1) Aircraft Reconnaissance Information
  ---------------------------------------

     Various types of messages from reconnaissance aircraft may be
  retrieved from the following FTP site:

     ftp://ftp.nhc.noaa.gov/pub/products/nhc/recon/>

     Information regarding how to interpret the coded reconnaissance
  messages may be found at the following URL:

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

  Links are also included to websites with further information about the
  U. S. Air Force 53rd Weather Reconnaissance Squadron and the NOAA Air-
  craft Operations Center.

  (2) Archived Advisories
  -----------------------

     All the advisory products (public advisories, forecast/advisories,
  strike probabilities, discussions, various graphics) issued by TPC/NHC
  are archived on TPC's website.  For the current year (using 2004 as an
  example), the archived products can be found at:

     http://www.nhc.noaa.gov/archive/2004/index.shtml>

  Links to tropical products archives for earlier years are available at
  the following URL:

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

  JTWC warnings for past storms are archived on the NRL Monterrey website:

     http://www.nrlmry.navy.mil/tc_pages/tc_home.html>

  On the NRL site, the link to past years can be found in the upper left 
  corner of the screen.

     I am not aware at the moment of any other TCWC which archives all
  its tropical cyclone warning/advisory products for public access, but
  if I learn of any, I will add them to this list.

  (3) Satellite Imagery
  ---------------------

     Satellite images of tropical cyclones in various sensor bands are
  available on the NRL Monterrey and University of Wisconsin websites,
  courtesy of Jeff Hawkins and Chris Velden and their associates.  The
  links are:

     http://www.nrlmry.navy.mil/tc_pages/tc_home.html>

  On the NRL site, the link to past years can be found in the upper left 
  corner of the screen.  For the CIMSS site, a link to data archives is 
  located in the lower left portion of the screen.

     Additional tropical satellite imagery, along with looping ability for
  composite microwave imagery for the Western Hemisphere north of the
  equator, can be found at:

  (4) Cyclone Tracking Information
  --------------------------------

     There is a U. S. Navy site that tracks tropical cyclones at 6-hourly
  intervals which often includes pre and post-advisory positions.  The
  link to the site is:

  http://www.nrlmry.navy.mil/atcf_web/doc_archives/>

     Steve Young has compiled many of these tracks onto a single webpage
  which is very user-friendly:

              !!!!!!  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:
