GLOBAL TROPICAL CYCLONE TRACKS - APRIL 2004

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 very special thanks to Michael for the assistance he
so reliably provides.

Note: The 10-min avg MSW values given in the above table were those
assigned by JMA. NMCC assigned a peak 10-min avg MSW of 100 kts for
Sudal, and 100 kts was the peak estimated by PAGASA during the four
days the typhoon was within that agency's AOR. The CWB of Taiwan's
peak 10-min avg MSW was 85 kts--the same as Japan's. HKO estimated
Sudal's peak MSW at 95 kts, but that agency did not issue real-time
warnings on the cyclone as it remained outside their AOR. The HKO
peak was taken from the "Overview of Tropical Cyclones in April 2004"
written by the agency. (A special thanks to Huang Chunliang for
compiling and sending the peak MSW information from the Asian TCWCs.)

NORTHEAST AUSTRALIA/CORAL SEA (AUE) - Longitude 135E to 160E
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 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.

Note: The initial Brisbane gale warnings forecast that gales would
develop, but apparently they did not actually occur, at least near the
center, as the system was not named. The final reference to this LOW was
in the Darwin Tropical Cyclone Outlook on 21 April, mentioning a 1009-mb
weak tropical LOW in the Arafura Sea.

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.

!!!!!! 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:
http://199.10.200.33/jtwc.html>
SPECIAL NOTE: Back issues of the global tropical cyclone summaries
and monthly cyclone track files can be obtained at the following
websites:
