           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.

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.
