            GLOBAL TROPICAL CYCLONE TRACKS - NOVEMBER 1999

ATLANTIC (ATL) - North Atlantic Ocean, Caribbean Sea, Gulf of Mexico

NOTE:  The tracking and intensity information for Atlantic Basin
       tropical cyclones is based upon operational advisories from
       the Tropical Prediction Center/National Hurricane Center,
       located in Miami, Florida, USA.  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.

be starting to develop some tropical characteristics.

Note:  Most of this track was constructed from the High Seas Warnings
issued by the Marine Prediction Center and the Tropical Prediction
Center.  The portion of the track from 1200 UTC on 29 Nov through
0000 UTC on 1 Dec was based primarily on information sent to me by
John Wallace.  This gale center was mentioned in the Tropical Weather
Outlooks issued by TPC/NHC from 24-30 Nov.  On 30 Nov, the last day of
the official Atlantic Hurricane Season, the system appeared to be
developing significant tropical characteristics, but this trend was
soon halted and the LOW began to slowly weaken.

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.

Note:  This is most perplexing!  Initially JMA was certainly tracking
the same LLCC as JTWC, but from 06/1200 UTC it appears that JMA was
following another LLCC.   Since I don't have any JMA information at
0600 UTC and since, unfortunately, JMA doesn't have any numbering or
otherwise identification scheme for tropical depressions, I have no idea
exactly what lies behind this huge discrepancy.    Since the 1200 UTC 
warning was the last from JTWC, the coordinates from that point forward 
represent whatever it was that JMA was tracking.   Perhaps this wasn't 
the best procedure to follow, but hopefully this explains it adequately.

Note:  The sudden increase in JTWC's MSW estimate from 40 kts to 65 kts
suggests that quite likely the 40-kt value at 15/1200 UTC was too low.

                          ADDITIONAL TRACKS for
                         NORTHWEST PACIFIC BASIN
                            TROPICAL CYCLONES

The following tracks are for three interesting systems which occurred
in the Northwest Pacific basin during November and for which tropical
cyclone warnings were not issued.    With the exception of the first,
the tracks 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.

In keeping with the policy I established a few months ago, I have 
chosen to unofficially refer to these systems with letters of the Greek 
alphabet.  These Greek letter designations are just for the purpose
of having some "handle" by which to refer to interesting systems which
are both unnamed and unnumbered.   Any person doing further research
or analysis on them is free to use the names if they choose--they need
not feel compelled to do so.

Note:  No regular warnings were issued by JTWC on this system, which was
a monsoon depression.   All the positions except 04/2230 UTC were taken
from daily Significant Tropical Weather Outlooks (STWO).  That position
was taken from an e-mail received from Mark Lander.   Likewise, the MSW 
values given above were taken from the STWOs.  According to Dr. Lander,
gale-force winds were occurring in the primary cloud band to the north
and east of the LLCC and were probably nearing gale-force near the core
at landfall.

Note:  This system did not reach tropical storm intensity while still
classifiable as a tropical depression.   Intensification on and after
12 Nov was as a hybrid, subtropical-type cyclone.

Note:  In contrast to "Eta" above, which was an unusual example of a
system from the deep tropics evolving into a hybrid, subtropical storm,
"Theta" represents just the opposite type of transformation--the more
usual case of a subtropical cyclone acquiring tropical characteristics.

SOUTHWEST PACIFIC (SWP) - South Pacific Ocean East of Longitude 160E

NOTE:  The tracking and intensity information for Southwest 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 (west of 180) and from
       NPMOC (east of 180) 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 JTWC or
       NPMOC warnings.  (NOTE: JTWC did not issue any warnings on the
       depressions listed below.)

Note:  Gales were experienced only in the southern semicircle.  In WMO
Region 5 (Australia and the South Pacific), the basic definition of a
tropical cyclone contains the criterion that gales more or less
surround the center.  This system was likely more of a hybrid depression
than purely tropical.

Note:  This system was never referred to in warnings from Fiji as a
tropical depression, but only as a depression, and from 13/1800 UTC
on, it was referred to simply as a LOW.  As with the previous system,
this disturbance was likely a hybrid or even primarily baroclinic sort
of depression.
