Monthly Global Tropical Cyclone Tracks January 1998 [Summaries and Track Data] [Prepared by Gary Padgett] |
GLOBAL TROPICAL CYCLONE TRACKS - JANUARY 1998
SOUTH INDIAN OCEAN (SIO) - South Indian Ocean West of Longitude 90E
NOTE: The tracking and intensity information for South Indian Ocean
Basin tropical cyclones is based upon operational warnings from
the Joint Typhoon Warning Center of the U.S. Air Force and Navy
on the island of Guam. 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.

AUSTRALIAN REGION (AUS) - From Longitude 90E Eastward to Longitude 160E
NOTE: The tracks presented below are based on operational warnings
from the Australian Tropical Cyclone Warning Centres at
Darwin (Northern Territory), Brisbane (Queensland), and Perth
(Western Australia).
The MSW in the tables below are based on a 10-min averaging
period. To convert these to equivalent 1-min average winds,
multiply by 1.15. However, the wind speed estimates by
JTWC mentioned in the Remarks column, are 1-min average
sustained winds. To convert these to equivalent 10-min
average winds, multiply by 0.87.

System merged/captured by TC Susan by 09/0000 UTC.
NOTE: There were several instances where NPMOC's 1-min MSW did not agree
too closely with Fiji's 10-min avg sustained winds. However, the peak
MSW reported by NPMOC of 155 kts, equivalent to a 10-min avg wind of 135
kts, agrees rather well with the 125 kts reported by Fiji. In fact, the
Nadi discussion at 06/0800 UTC mentioned that, based on winds reported
from Niuafo'ou, Ron might be an even more compact system with stronger
winds near the center than previously thought. Whether or not the peak
winds will be raised during post-season analyis remains to be seen.

NOTE: The maximum sustained 1-min avg wind reported by JTWC was 140 kts.
Converting 125 kts (10-min avg) to its equivalent 1-min avg MSW yields
144 kts, so this represents an excellent agreement between the two
warning centers' estimation of Susan's peak intensity.
