GLOBAL TROPICAL CYCLONE TRACKS - MAY 2009
!!!! IMPORTANT -- PLEASE SEE NOTE AT END OF FILE !!!!
MAY HIGHLIGHTS
--------------
--> Two typhoons form in Northwest Pacific--one strikes Philippines
--> Deadly cyclone strikes India and Bangladesh
GLOBAL OVERVIEW
---------------
The most active basin during May was the Northwest Pacific, where
two typhoons formed early in the month. Typhoon Kujira (Dante) formed
just east of the Philippines and tracked off to the northeast, passing
north of the Marianas and not too far south of Iwo Jima. Typhoon
Chan-hom (Emong) formed at about the same time in the South China Sea
and also moved northeastward, striking northwestern Luzon. Also,
during the first week of the month, JMA classified a system well east
of the Philippines as a tropical depression.
A severe cyclonic storm, Aila, formed in the Bay of Bengal and
struck India and Bangladesh, causing a considerable number of
fatalities. During the final week of the month, a tropical depression
formed over warm Gulf Stream waters off the U. S. East Coast but moved
on northeastward and out to sea without reaching tropical storm status.
No tropical cyclones nor significant tropical LOWs formed in the
Southern Hemisphere during May.

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 located in Miami, Florida. A 1-minute averaging
period is the standard used by all U. S. civilian and military
warning services for tropical cyclone warnings.

Note: The above information was sent to the author by Steve Young and is
based on NRL data. This system was not classified as a tropical
depression, but was close to depression status as it neared the Gulf
Coast. The LOW brought significant rainfall amounts to portions of the
southern states. The final data point in the track above is well off-
shore. The LOW's center made landfall near the Mississippi/Alabama
border around 1500 UTC 23 May. There are also some data points missing
between 19/0000 and 21/1200 UTC.

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.
Following is the link to the Wikipedia page for the 2009 Pacific
Typhoon Season. Detailed reports for Typhoons Kujira and Chan-hom are
already available.
http://en.wikipedia.org/wiki/2009_Pacific_typhoon_season>
Following are links to Michael Padua's storm logs for the two
May typhoons, plus a tropical depression (Crising) in late April.
PAGASA reported this system's winds at 30 kts, but it was not elevated
to depression status by either JMA or JTWC.

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.
Following is the link to the Wikipedia page for the 2009 North
Indian Ocean Cyclone Season. A detailed report for Severe Cyclonic
Storm Aila is already available.

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

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:

(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:

!!!!!! 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:
