GLOBAL TROPICAL CYCLONE TRACKS - SEPTEMBER 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.

ADDITIONAL TRACKS for ATLANTIC BASIN
POSSIBLE TROPICAL CYCLONES
There were two interesting weather systems in the North Atlantic
subtropics only a few days apart in mid-September which possibly may
have been tropical cyclones. I am including preliminary tracks on
these systems which were prepared by two young and rather knowledgeable
tropical cyclone enthusiasts. Some sketchy information on each follows
the tracks. In keeping with the policy I established last month, 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: In a telephone conversation on 27 Sep, Jack Beven then informed
me that this system would likely be included as an unnumbered, non-
operational tropical depression in the annual Tropical Weather Systems
article prepared by the staff of NHC. I have since learned from Chris
Landsea that Jack is seeking surface wind observations taken in the
vicinity of this system to see if there is justification for writing it
up as an unnamed tropical storm. I know that John Wallace based his
estimate of 35-kt winds for 14-15 Sep on CIMSS low-level wind analyses
which yielded winds of 35-40 kts in the lower levels (but not necessarily
at the surface) and at some distance from the center of the cyclone.
This LOW did exhibit a very well-defined, tight LLCC but with deep
convection sheared well away to the east. In the author's opinion, it
was the lack of central convection which largely was responsible for
TPC/NHC not classifying this system at least as a tropical depression
operationally.

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: Normally when comparing positions from JTWC, PAGASA, and JMA, two
of the three will usually be fairly close together. But the synoptic
positions on 13 Sep from the three agencies diverged considerably. The
PAGASA positions are given above, and for completeness, I am listing the
JMA positions here:

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
depression listed below.)

Note: According to Alipate Waqaicelua, Chief Forecaster at the Nadi
TCWC, this system likely was a hybrid and not a purely tropical
depression. A reminder--the official definition of a tropical cyclone
in WMO Region V (Australia and the South Pacific) requires that the
center of the system be surrounded by gales (winds > 33 kts); hence,
there are often depressions with gale-force winds in only one or two
quadrants which do not qualify to be named as tropical cyclones.
