Monthly Global Tropical Cyclone Tracks November 1998 [Summaries and Track Data] [Prepared by Gary Padgett] |
GLOBAL TROPICAL CYCLONE TRACKS - NOVEMBER 1998
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.

the information was supplied by TPC/NHC. The extratropical portion of
Nicole's track from 1800 UTC on 1 Dec onward was based upon the HSF.

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: MSW (10-min) at 24/0000 UTC from PAGASA. At 24/0600 UTC PAGASA
was reporting 40 kts (10-min), but JMA's MSW was 30 kts, and JTWC's
1-min MSW was only 25 kts; hence, I subjectively reported 35 kts at this
point for continuity. PAGASA ceased issuing advisories after 24/1200
UTC.

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.

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 Centre
at Perth, Western Australia. JTWC warnings were utilized for
making comparisons and supplying information for times when the
Perth warning was unavailable. The 10-min MSW values were
obtained from the Perth 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.
