                GLOBAL TROPICAL CYCLONE TRACKS - MAY 2010

      !!!! IMPORTANT -- PLEASE SEE INFORMATION AT END OF FILE !!!!


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.

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: Roger Edson expressed a very firm feeling that Laila was 
considerably more intense than any of the agencies were estimating.
Based on an integrated MI and Dvorak technique, Roger estimates that
Laila's intensity around 18/1200 UTC was around 90 to 105 kts (1-min
avg).

                   ********** 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 July 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/>
