               GLOBAL TROPICAL CYCLONE TRACKS - APRIL 2002

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 and central pressure estimates were obtained from
       JMA's advisories.

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

NOTE:  The tracking information presented below was obtained from
       operational warnings issued by the Tropical Cyclone Warning
       Centres at Perth, Western Australia, and Darwin, Northern
       Territory.  Also, the central pressure estimates and 10-min
       avg MSW values were obtained from Perth's and Darwin's advices
       and warnings while the 1-min avg MSW was taken from JTWC's
       warnings.   For positions east of longitude 90E, the central
       pressure and 10-min avg MSW estimates were obtained from warnings
       issued by the La Reunion TCWC.

       25S and from the Wellington, New Zealand office for positions
       south of 25S.

Note: The Tropical Disturbance Summaries issued by Nadi did not give any
maximum sustained wind estimates.  However, they did note that stronger
winds were occurring on the southern flank of the system from the 18th
to the 21st due to the gradient with a strong HIGH centered near New
Zealand.  By the 22nd the HIGH had moved eastward and the winds eased.

             !!!!!!  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.
