NORTHEAST PACIFIC (NEP) - North Pacific Ocean East of Longitude 180

NOTE:  The tracking and intensity information for Northeast Pacific
       Basin tropical cyclones is based upon operational advisories
       from the Tropical Prediction Center/National Hurricane Center
       in Miami, Florida, for systems east of Longitude 140W; and
       from the Central Pacific Hurricane Center, Honolulu, Hawaii,
       for systems west of Longitude 140W.  The MSW are based on a
       1-min averaging period, which is used by all U.S. civilian
       and military weather services for tropical cyclone warnings.

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.

       Michael V. Padua, owner of the Typhoon 2000 webpage, sent me the 
       PAGASA and JMA tracks for Tropical Storm Cimaron/Crising--a
       special thanks to Michael for his assistance.   The track for the
       second system, an unnamed/unnumbered tropical depression, was
       compiled and sent to me by Roger Edson of the University of Guam.
       A special thanks to Roger for sending me this track.

SOUTH PACIFIC (SPA) - South Pacific Ocean East of Longitude 160E

NOTE:  The tracking and intensity information for South Pacific
       Basin tropical cyclones was taken from real-time operational
       warnings issued by the Nadi TCWC, Fiji for positions north of
       25S and from the Wellington, New Zealand office for positions
       south of 25S.  Warnings from JTWC were utilized for the purpose
       of making comparisons and for supplying information for times
       when the Nadi or Wellington warnings were unavailable.   The
       10-min avg MSW values were taken from the Fiji or New Zealand
       warnings while the 1-min avg MSW values were obtained from the

semicircle as the system moved closer to a strong ridge to the south.

             !!!!!!  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 (ATCR) 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>

     For the actual Best Tracks files, click on the link for Best Tracks
  (in the menu on the left side of the screen) and follow instructions.

     In the ATCR for 2000, the Chapter 5 tab contains verification
  statistics of JTWC warnings for all the 2000 tropical cyclones in the
  Northwest Pacific, North Indian Ocean, and the Southern Hemisphere.
  There are gaps in the Best Tracks presented here for certain cyclones
  during periods in which no warnings were being issued.
