GLOBAL TROPICAL CYCLONE TRACKS - APRIL 2009
!!!! IMPORTANT -- PLEASE SEE NOTE AT END OF FILE !!!!
APRIL HIGHLIGHTS
----------------
--> First Northern Hemisphere cyclone of year forms--makes landfall
in Bangladesh
--> Tropical cyclones affect Madagascar and Tonga
GLOBAL OVERVIEW
---------------
As is typical for the transition months, tropical activity occurred
in both hemispheres during April. In the Northern Hemisphere, Cyclonic
Storm Bijli formed in the west-central Bay of Bengal and initially
moved northward, intensifying to 50 kts (per JTWC). Bijli then turned
toward the northeast, paralleling the Indian coastline, and began to
weaken as it neared its landfall in Bangladesh. Several fatalities
were attributed to Bijli. Late in the month, a low-pressure area in
the South China Sea was dubbed Tropical Depression Crising by PAGASA,
but was not elevated to depression status by either JTWC or JMA. I did
not prepare a track for Crising, but following is a link to Michael
Padua's PAGASA track for this system:
http://www.typhoon2000.ph/stormarchives/2009/stormlogs/03crising09_log.htm>
The only Southwest Indian Ocean system to form during the month was
Severe Tropical Storm Jade, which struck eastern Madagascar just shy
of cyclone (i.e., hurricane) intensity, leaving 15 dead and nearly
23,000 homeless. MFR's peak intensity for Jade was 60 kts, and JTWC
briefly elevated their 1-min avg MSW to 65 kts.
One minimal tropical cyclone formed in the Australian Region, and in
a very unusual location. Tropical Cyclone Kirrily formed in the
northern Arafura Sea very deep in the tropics in a region where few
cyclones form. The system made landfall in the Aru Islands and
weakened thereafter. Around mid-month a non-tropical LOW formed in
subtropical latitudes just east of 160E in Fiji's AOR. This system
over the next several days drifted westward into Brisbane's AOR and
produced gales. The LOW exhibited subtropical cyclone characteristics
in satellite imagery and may have briefly become a tropical cyclone.
(See the comments following the track for this system below.)
One tropical cyclone formed east of 160E--Tropical Cyclone Lin. The
predecessor of Lin moved eastward through the islands of Fiji before
turning south-southeastward and intensifying. Lin reached a peak
intensity of 60 kts (10-min avg) and passed through the Kingdom of
Tonga where minor damage was reported. A track is also included below
for a system in mid-April well east of the Dateline which exhibited
some subtropical features in satellite imagery. Following Lin, another
system was numbered Tropical Disturbance 15F by Nadi but was not
accorded depression status.

NORTH INDIAN OCEAN (NIO) - Bay of Bengal and Arabian Sea
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. Occasionally some information may
have been gleaned from the daily tropical weather outlooks and other
bulletins issued by the Indian Meteorological Department (IMD), which
is the World Meteorological Organization's Regional Specialised Meteor-
ological Centre for the basin.
The reported maximum sustained winds are based on a 1-minute
averaging period, which is used by all U. S. civilian and military
weather services for tropical cyclone warnings. For synoptic
observations in the North Indian Ocean region, both 10-minute and
3-minute average winds are employed, but IMD makes no attempt to
modify the Dvorak scale for estimating tropical cyclone intensity;
hence, a 1-minute average MSW is implied.

Indian Ocean Cyclone Season. A detailed report on Cyclonic Storm
Bijli is available.

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

Note: The information prior to 18/0600 UTC was based on BoM analysis and
was supplied to the author by Steve Young. The positions and CP values
from 22/1200 UTC onward were also sent by Steve Young and were based upon
NCEP re-analyses. An e-mail from Derrick Herndon on 23 April noted that
the AMSU intensity algorithm suggested a CP of 970 mb and winds of
70 kts. Derrick also noted that recent QuikScat imagery indicated wind
flags of 60 kts for the "at least" intensity. The LOW at this time
sported a large eye-like feature, and since it appeared to be warm core
and driven by convective instead of baroclinic processes, Derrick was
of the opinion that it qualified as a tropical cyclone.

Note: The above track was sent to the author by Steve Young, and was
based upon NCEP reanalysis data. The wind speed values are given only
for occasions where there was a satellite bulletin from SAB available.
Satellite composites and a BOM analysis at 15/0000 UTC showed convection
associated with the South Pacific Convection Zone (SPCZ) reaching from
10S/180E to 38S/155W where it merged with a old frontal zone. To the
west was a separate, disorganized cloud mass. By 16/0000 UTC there was
a small circulation with clouds about 5 degrees from the SPCZ. The
cloud mass remained separate from the SPCZ, and was disorganized through
the life of the system.

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:

!!!!!! 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/>
