GLOBAL TROPICAL CYCLONE TRACKS - DECEMBER 2010

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 special thanks to Michael for his efforts.

Note: The track above to 18/0600 UTC is based on NWS Honolulu high seas
forecasts. From 18/2100 through 20/0000 UTC the information was
supplied by Dr. Karl Hoarau. (A special thanks to Karl for providing
the information.) The remainder of the track is based on CPHC tropical
cyclone warnings and high seas forecasts. The 10-min avg MSW and CP
values prior to 20/0600 UTC were taken from JMA high seas bulletins,
which treated the system no higher than a 30-kt tropical depression.

Note: Karl's estimated peak intensity of 70 kts at 19/1500 UTC is
supported by SAB's rating of T4.5/4.5 at the same time. There was quite
a spread in the warning agencies' estimates at this time, ranging from
T4.5/4.5 (SAB) to apparently a T2.0/2.0 from JMA, with CPHC fitting in
with T3.5/3.5 and JTWC assigning a subtropical rating of ST3.5.

NORTHWEST AUSTRALIA/SOUTHEAST INDIAN OCEAN (AUW) - Longitude 90E to 135E
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.

********** SPECIAL NOTE **********
I now have some assistants who are helping to prepare the monthly
tropical cyclone files, and I'd like to thank them for their willing-
ness to assist me. Kevin Boyle, of Stoke-on-Trent, UK, will be
preparing the tracks for Northwest Pacific basin tropical cyclones
during the most active part of the NWP season from June through
December.
Michael Bath, of McLeans Ridges, New South Wales, Australia, is now
preparing the track files for Australian Region and South Pacific
tropical cyclones. Also, Steve Young sends me tracks with data for
the pre-warning and post-warning stages of tropical cyclones in all
basins, prepared primarily from NCEP re-analysis data or else taken
from NRL files.
A very special thanks is due to Kevin, Michael and Steve for their
assistance.

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:
http://home.earthlink.net/~shy9/tc1.htm>
*************************************************************************
!!!!!! 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://www.usno.navy.mil/JTWC>
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/>
