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 were obtained from PAGASA's advisories if the
       storm was in PAGASA's area of responsibility; otherwise, they
       were gleaned from JMA's advisories or high seas forecasts.  In
       a few cases the 10-min MSW given by PAGASA and JMA did not agree;
       in those cases I reported the higher value.    The estimates of
       central pressure were obtained from JMA's advisories.

       Michael V. Padua, owner of the Typhoon '99 webpage sent me the 
       PAGASA and JMA tracks for these systems--a special thanks to 
       Michael for his assistance.

the fact that the previous values were taken from the PAGASA track, but
the remaining estimates were obtained from JMA's track.

                     ADDITIONAL and ALTERNATE TRACKS
                       for NORTHWEST PACIFIC BASIN
                           TROPICAL CYCLONES

This is a "first" in the series of Global Tropical Cyclone Tracks files
which have been prepared by the author since October, 1997.  Heretofore,
I have always included just one track file for each cyclone, using
the Remarks column to indicate significant differences in positions
between JTWC and other warning agencies.   During August, in the
Northwest Pacific basin, the monsoon trough intruded to rather high
latitudes, leading to a rather spectacular outbreak of small-scale
convective cyclones.  There was wide disagreement among satellite
intensity estimates and the manner in which these systems were treated
by JTWC and JMA.

The tracks below were supplied by Dr. Mark Lander, a professor at the
Water and Environmental Institute of the Pacific at the University of
Guam.    From 1988 to 1998, Dr. Lander (who earned his Doctorate from
the University of Hawaii in 1986) was funded by the Office of Naval
Research to conduct research on tropical cyclones.  During much of
this time Mark worked at JTWC alongside the forecasters and satellite
analysts, helping them to decide what basic research could best help
them solve some of the problems encountered in their day-to-day work.

Three systems are included for which neither JTWC nor JMA issued any
warnings.   Following are alternate tracks prepared by Mark for Typhoons
Tanya and Virgil and Tropical Depression 18W.   In general Mark's
intensities represent the most liberal estimates while JMA's are the
most conversative and JTWC's more or less in the middle.   It appears
that part of the problem is that the widely-used Dvorak method of
satellite analysis for tropical cyclones does not handle such midget
systems well.   A case in point--in late August in the Atlantic a
midget tropical cyclone formed in the deep tropics--Tropical Storm
Emily.   The satellite signature on 24 Aug didn't look anything like
a tropical storm, yet a reconnaissance flight found a tightly-wound
midget tropical storm only 10 kts shy of hurricane force!

It is the author's hope that by including these systems some qualified
persons will conduct further studies of these small cyclones and other
similar systems.  In order to provide a distinctive identification for
these storms since they were not assigned any name or number by any
TCWC, I have chosen to designate them with letters of the Greek
alphabet.  The regular summary will have some more information on
this.

NORTH INDIAN OCEAN (NIO) - Bay of Bengal and Arabian Sea

NOTE:  The tracking and intensity information for North Indian Ocean
       Basin tropical cyclones is based primarily upon operational
       warnings from the Joint Typhoon Warning Center of the U.S. 
       Air Force and Navy (JTWC) at Pearl Harbor, Hawaii.  For weaker
       systems not in warning status by JTWC, information gleaned from
       the twice-daily issuances of the Indian Meteorological Depart-
       ment (IMD) was used to complete the tracks.  These bulletins
       usually give analyzed center positions at either 0300 or 0600
       UTC and 1200 or 1500 UTC.
       
       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.  For synoptic observations in the North Indian
       region, both 10-min and 3-min average winds are employed, but
       IMD makes no attempt to modify the Dvorak scale for estimating
       tropical cyclone intensity; hence, a 1-min avg MSW is implied.
       In the North Indian basin JTWC usually does not initiate warnings
       until a system is well-organized and it is likely to attain
       tropical storm status within 48 hours.

       Windspeeds are usually not reported in the IMD bulletins. Systems
       are usually classified as depressions, deep depressions, or
       cyclonic storms.   For depressions I assigned a MSW of 25 kts and
       for deep depressions 30 kts.  If the early stages of a system 
       were referred to as a low-pressure area, I assigned 20 kts.

Note: The MSW estimates are my own, based upon the fact that IMD never
called this system a "deep depression", which would imply 30-kt winds.
The final two values are based upon the fact that the system was inland
and weakening.
