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.

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: 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.

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>
http://cimss.ssec.wisc.edu/tropic/tropic.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:
(1) For the Eastern North Pacific:
http://www.ssd.noaa.gov/PS/TROP/trop-epac.html>
(2) For the Atlantic, Gulf of Mexico and Caribbean Sea:
http://www.ssd.noaa.gov/PS/TROP/trop-atl.html>
(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:
http://home.earthlink.net/~shy9/tc1.htm>
***************************************************************************
*************************************************************************
!!!!!! 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:
https://metocph.nmci.navy.mil/jtwc.php>
SPECIAL NOTE: Back issues of the global tropical cyclone summaries
and monthly cyclone track files can be obtained at the following
websites:
ftp://ftp.aoml.noaa.gov/hrd/pub/landsea/padgett/>
http://australiasevereweather.com/cyclones/>
