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.

Note: The above track from 30/0600 UTC through 1800 UTC on 1 August
is based upon satellite fix bulletins from SAB.   I arbitrarily 
assigned the following MSW values based upon CI intensity numbers:

1.5       =  25 kts
1.0       =  20 kts
TOO WEAK  =  15 kts

                        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).  Also, Huang Chunliang of Fuzhou City, China, sends me
  each month a table comparing the maximum intensities assigned to each
  cyclone from all the applicable warning centers in the Northwest
  Pacific basin.  A very special thanks to Michael and Chunliang for
  the assistance they so reliably provide.

Note: Huang Chunliang is away in Shanghai during July and August for
a job-related training course, and is unable to provide the MSW
comparisons which he has been compiling.  If he should send these
to me at a later date, I'll include them as an addendum to a future
summary.  However, I do have available the PAGASA data for the portion
of Tropical Storm Kompasu/Julian's track which fell in that agency's
AOR.  The peak 10-min avg MSW estimated by PAGASA was 40 kts just prior
to the cyclone's exiting their region of responsibility.

Note: Huang Chunliang is away in Shanghai during July and August for
a job-related training course, and is unable to provide the MSW
comparisons which he has been compiling.  If he should send these
to me at a later date, I'll include them as an addendum to a future
summary.

Note: NMCC was the only warning agency to upgrade this system to tropical
storm status, although the satellite fix bulletin from SAB at 0225 UTC
on 27 July supported tropical storm intensity.  Some coastal stations
in China reported wind gusts in the 50 to 60-kt range which also tend to
suggest this system was of tropical storm intensity.   JMA issued one
bulletin on this LOW as a 30-kt (10-min avg) tropical depression.  (The
above NMCC track was sent by Huang Chunliang--a special thanks to
Chunliang for sending the information.)

             !!!!!!  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://199.10.200.33/jtwc.html>


  SPECIAL NOTE:  Back issues of the global tropical cyclone summaries
  and monthly cyclone track files can be obtained at the following
