GLOBAL TROPICAL CYCLONE TRACKS - APRIL 2006
!!!! IMPORTANT -- PLEASE SEE NOTE AT END OF FILE !!!!
*************************************************************************
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.

Note: The starting point for the above track was JTWC's 12-hourly
warnings, issued at 0600 and 1800 UTC, beginning at 24/1800 UTC, plus
extra warnings issued at 26/1200 and 29/1200 UTC. For the other 1200
UTC times, plus all the 0000 UTC points, I utilized the satellite
bulletins from JTWC and AFWA, issued at 1130 and 2330 UTC. There is
no track point for 26/0000 UTC as I did not have the satellite bulletins
saved. I did have a warning at that time from IMD which placed Mala's
center at 10.4N/89.0E, but did not include it as the trend of JTWC's
positions at that time was eastward, and including the IMD position
would make a westward jog which I did not feel was real. One additional
thing--there was no warning issued at the peak intensity time of
28/1200 UTC. However, both JTWC and AFWA assigned Dvorak ratings of
T6.5/6.5 at that hour, so it seems likely that Mala reached a peak
intensity of 125 kts about that time.

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: There is a slight possibility that Tropical Storm Elia was a
redevelopment of a tropical LOW tracked in the Perth region on
26-27 March, but I did not have enough information to make a certain
connection; hence, I have treated Elia as a separate entity. The data
points in the above track between 08/0600 and 11/1200 UTC, inclusive,
were taken from JTWC's satellite fix bulletins as no agency was issuing
warnings on the system during that time.

!!!!!! 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:
