GLOBAL TROPICAL CYCLONE TRACKS - FEBRUARY 1999
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 on
the island of Guam. 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.

Note: I was not able to retrieve JMA bulletins for this system; hence,
all the 10-min MSW estimates are taken from the PAGASA track supplied me
by Michael V. Padua. Since JMA warnings were unavailable, there are
no central pressure estimates except for the ones given by JTWC in their
Significant Tropical Weather Outlooks during the formative stages.

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) on the island of Guam. 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.

SOUTH INDIAN OCEAN (SIO) - South Indian Ocean West of Longitude 90E
NOTE: The tracking coordinates, 10-min avg MSW, and estimates of
central pressure were obtained from the RSMC La Reunion's
advisories, while the 1-min avg MSW were taken from JTWC's
advisories. In the case of TS Chikita and TD D19899, the
coordinates and 10-min MSW were taken from an analyzed
Best Track prepared by the La Reunion TCWC. A special
thanks to Philippe Caroff for sending the track to me.

AUSTRALIAN REGION (AUS) - From Longitude 90E Eastward to Longitude 160E
NOTE: The tracking information presented below was obtained from
operational warnings issued by the Tropical Cyclone Warning
Centres at Perth, Western Australia; Darwin, Northern Territory;
and Brisbane, Queensland. JTWC warnings were utilized for
making comparisons and for supplying information for times when
the Australian warnings were unavailable. The 10-min MSW values
were obtained from the Australian warnings while the 1-min MSW
values were assigned by JTWC.
The tropical cyclone warnings from Perth report the analyzed
cyclone positions at 0400, 1000, 1600, and 2200 UTC instead of
the more familiar 0000, 0600, 1200, and 1800 UTC utilized by most
TC warning agencies. I have made no attempt to interpolate the
coordinates to standard synoptic hours as I did last season.

Note: JTWC obviously tracked "something" inland while Brisbane has
Rona's remnants staying near the coast, later moving back out into
the Pacific and subsequently re-developing into Tropical Cyclone Frank
in the Fiji AOR. This last position was taken from JTWC's final
warning. Based upon comments in the last JTWC warning, the "something"
was likely the upper-level (convective) portion of the circulation
while the lower-level portion got caught up in the Great Dividing Range
and later drifted back out to sea.

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.

south of where Fiji's track begins. I included them because they
represent the earliest information I had available on this cyclone.

Note: Two positions above were posted to a discussion list by Dr. Mark
Lander of the University of Guam, who was unaware that any agency was
issuing warnings on this system. According to some e-mail from Steve
Ready of the New Zealand Meteorological Service, it is very possible
that Gita was declared extratropical a bit prematurely. Also, the
monthly write-up I received from Alipate Waqaicelua of the Fiji TCWC
stated that probably Gita should have been upgraded to a tropical
cyclone at 27/0000 UTC.
