Monthly Global Tropical Cyclone Tracks December 2000 [Summaries and Track Data] [Prepared by Gary Padgett] |
GLOBAL TROPICAL CYCLONE TRACKS - DECEMBER 2000
!!!!!! 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.

NORTHWEST PACIFIC (NWP) - North Pacific Ocean West of Longitude 180
NOTE: The tracking information for Northwest Pacific Basin tropical
cyclones is based primarily upon operational warnings from the
Joint Typhoon Warning Center of the U.S. Air Force and Navy at
Pearl Harbor, Hawaii. Comparisons were made with track coordinates
given in advisories from the meteorological services of Japan
(JMA) and the Philippines (PAGASA). In general, whenever the
center position differed by more than 40-50 nm from JTWC's, an
entry was made in the Remarks column.
The 1-min avg MSW were taken from the JTWC advisories while the
10-min avg MSW were obtained from PAGASA's advisories if the
storm were in PAGASA's area of responsibility; otherwise, they
were gleaned from JMA's advisories or high seas forecasts. In
a few cases the 10-min MSW given by PAGASA and JMA did not agree;
in those cases I reported the higher value. The estimates of
central pressure were obtained from JMA's advisories.
Michael V. Padua, owner of the Typhoon 2000 webpage sent me the
PAGASA and JMA tracks for these systems--a special thanks to
Michael for his assistance.

Note: Some PAGASA positions are:
28/1800 UTC - 8.0 N, 130.0 E
29/0000 UTC - 8.3 N, 130.0 E
29/0600 UTC - 8.3 N, 129.8 E
29/1200 UTC - 8.4 N, 129.6 E
After 29/1200 UTC PAGASA positions were generally quite close to either
JTWC's or JMA's coordinates. The final JMA position, at 05/0000 UTC,
was 18.0 N, 138.2 E. The final JTWC coordinates, as annotated above,
represent a severe relocation from the previous warning position, based
no doubt upon the first visible pictures of the day. The JMV file
prepared by JTWC contains revised center coordinates and MSW estimates
for the next-to-last two entries:
04/1200 UTC - 17.5 N, 136.8 E - 55 kts
04/1800 UTC - 16.5 N, 136.3 E - 40 kts
There likely are other differences between JTWC's operational track and
the post-storm JMV file (sent to me by Michael Padua), but I included
these points because of the drastic changes made for these parameters
at the 1200 and 1800 UTC analysis times.

NORTH INDIAN OCEAN (NIO) - Bay of Bengal and Arabian Sea
NOTE: The tracking and intensity information for North Indian Ocean
Basin tropical cyclones is based upon operational warnings from
the Joint Typhoon Warning Center of the U.S. Air Force and Navy
at Pearl Harbor, Hawaii. The MSW are based on a 1-min averaging
period, which is used by all U.S. civilian and military weather
services for tropical cyclone warnings. Some information was
also obtained from the Indian Meteorological Department (IMD).

south of 25S. Warnings from JTWC were utilized for the purpose
of making comparisons and for supplying information for times
when the Nadi or Wellington warnings were unavailable. The
10-min avg MSW values were taken from the Fiji or New Zealand
warnings while the 1-min avg MSW values were obtained from the
JTWC warnings. (NOTE: No warnings were issued by JTWC for the

Note: The Tropical Disturbance Summary issued at 12/2100 UTC was intended
to be the final one on this system as the depression was moving rapidly
southeastward into an area of increasing shear and cooler SSTs. The LOW
subsequently reached the vicinity of 170W and became quasi-stationary for
a couple of days. The gales occurred over an extensive area mainly along
the southern periphery of the system. All the gale warnings from
14/0600 UTC onward did not refer to the depression as a "tropical"
depression, thereby implying that it was likely more of a hybrid system.

Note: The gales associated with this depression were occurring well north
and east of the center. In WMO Region 5 (Australia/South Pacific), by
definition, to be named as a tropical cyclone a depression must have
gales more or less surrounding the center. Some of the gale warnings for
this depression did not contain the word "tropical", so it also may have
been somewhat hybrid in character: its location certainly suggests this.
