NORTHEAST PACIFIC (NEP) - North Pacific Ocean East of Longitude 180
Sources of Information
----------------------
The track coordinates, central pressure and 1-minute average
maximum sustained wind values were obtained from the operational
forecast/advisories issued by the Tropical Prediction Center/National
Hurricane Center in Miami, Florida, for locations east of longitude
140W, and from the Central Pacific Hurricane Center in Honolulu,
Hawaii, for locations west of longitude 140W. A 1-minute averaging
period is the standard used by all U. S. civilian and military
warning services for tropical cyclone warnings.

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). Also, Huang Chunliang of Fuzhou City, China, sends me
each month tracks obtained from warnings issued by the National
Meteorological Center of China (NMCC), the Central Weather Bureau
of Taiwan (CWBT) and the Hong Kong Observatory (HKO). A very
special thanks to Michael and Chunliang for the assistance they so
reliably provide.

Note: NMCC did not issue any warnings on this system, as they normally
only do so for systems which reach tropical storm intensity. However,
the Guangzhou Regional Meteorological Center (GRMC) did issue bulletins
on the tropical depression, and Huang Chunliang sent me their track.
No intensities were indicated, but the coordinates compared remarkably
well with those from JTWC, and the final one, at 29/1800 UTC, was very
close to PAGASA's position. Since the coordinates from PAGASA's track
at times differed significantly from both JTWC's and JMA's, I am
including them in the table below along with PAGASA's 10-min avg MSW

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: In the case of the third system included below, the LOW was
classified as a tropical depression only by the Meteorological
Department of Thailand. Huang Chunliang sent me their track for
this depression--a special thanks to Chunliang for sending the
information.

Note: IMD never classified this system as a cyclonic storm (i.e., a
tropical storm), at least through early on 9 May, the highest Dvorak
classification being T2.0. However, I do not have available any IMD
bulletins from late on the 9th and early on the 10th as the system
re-intensified and reached its peak intensity as it approached Oman.

inland at 18/0900 UTC near the location annotated above--in western
Myanmar. I do not know if the MSW estimates in the track from TMD
supplied by Chunliang represent 1-min avg or 10-min avg values, but
since JTWC estimated the highest 1-min avg MSW in this system at only
20-25 kts, I chose to treat them as 1-min avg winds. The two central
pressure estimates given above were obtained from JTWC's TCFA and
subsequent STWO.

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 Perth, Western
Australia, and Darwin, Northern Territory. 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: Normally for Southern Hemisphere tropical cyclones, I obtain the
coordinates from the official responsible warning agency. In the case
of Tropical Cyclone Upia, the track presented above was taken from
JTWC's warnings except for the last three positions. The reasons for
excepting my normal procedure were: (1) Port Moresby had computer
problems which prevented their earlier warnings from being received,
(2) Brisbane apparently placed some of their own analyses of Upia on
BoM's website for certain synoptic hours due to the unavailability of
Port Moresby's warnings, and (3) even with Brisbane helping out, I
still missed some of the warnings, which explains the gaps in the
Central Pressure and 10-min avg MSW columns. However, the center
position coordinates in general agreed quite well with those from
JTWC with only three annotations needed in the Remarks column.

!!!!!! IMPORTANT NOTE - PLEASE READ !!!!!!
It has been brought to my attention that I should repeat in the
cyclone tracks file the caveat which is included in the Author's
Note at the end of the cyclone summaries. The tropical cyclone
tracks which I prepare are based upon the operational warnings/
advisories/advices/bulletins from 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>
In the near future I shall contact the other tropical warning
centers to see if I can locate any links to sites where their "best
tracks" might be archived.
