GLOBAL TROPICAL CYCLONE TRACKS - JUNE 2011
!!!! IMPORTANT -- PLEASE SEE INFORMATION AT END OF FILE !!!!
+++++ IMPORTANT NOTE BY AUTHOR -- PLEASE READ +++++
Effective this month, I am making a change in the manner in which
I report the coordinates and MSW/CP for the Atlantic and Northeast
Pacific basin tropical cyclones. NHC (and CPHC) issue advisories at
three hours past the standard synoptic hours of 0000, 0600, 1200, and
1800 UTC. (In the following discussion, I refer to the advisory times
as SynHr+3.) Whenever any coastline is under a tropical storm watch
(or higher) intermediate bulletins are issued at the synoptic hours.
The regular advisories issued at SynHr+3 contain a line giving the
position coordinates for the previous synoptic hour.
My procedure has always been to time stamp each line with synoptic
hour and report the coordinates for that hour, but taken from the
regular advisory issued at SynHr+3. However, there is no MSW estimate
included for the previous synoptic hour; the MSW is always the best
estimate available at SynHr+3. Hence, in the case of TCs with rapidly
changing intensities, this can result in a discrepancy which could be
significant in some cases.
Whenever intermediate bulletins were being issued, I would glean the
coordinates from the regular advisory at SynHr+3 (which might not match
exactly the values reported in the intermediate advisory three hours
earlier), but would take the MSW directly from the intermediate
advisory issued at the synoptic hour. Whenever a hurricane is
approaching the U. S. coastine and moves into radar range, NHC's
procedure is to issue two intermediate advisories at SynHr-1 and
SynHr+1 hours. In these situations, I would still use the coordinates
for the synoptic hour taken from the SynHr+3 advisory, but average the
MSW and CP from the two intermediate advisories and report those
averages for the particular synoptic hour under consideration.
My procedure now is going to be to time stamp the entries in the
tabular tracks with the actual advisory time (SynHr+3) and report both
coordinates and intensity parameters at the stated time. Whenever an
initial (or otherwise) special advisory upgrading or downgrading a
system is issued at an intermediate hour, I will include an extra entry
to document that event. This will give the advantage of having the
position estimate and MSW/CP estimates relate to the same time, plus
will save me much time in that I won't have to store and then later
click open all the intermediate bulletins--only those few I need to
save for documenting an upgrade or downgrade or some other noteworthy
event.

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.

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 highest Dvorak ratings from SAB and JTWC on 16 June prior to
the system's moving inland were T2.0/2.0. JTWC rendered a rating of
T2.5/2.5 at 16/2330 UTC after the depression had moved inland. The
track above is based entirely on bulletins issued by the IMD.
Following is an alternate track for Invest 99B, sent to the author by
Steve Young. The position, pressure and MSW are based upon NRL data.
Another value for pressure, based upon NCEP reanalysis data, is included

********** 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/>
