GLOBAL TROPICAL CYCLONE TRACKS - FEBRUARY 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) 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.

SOUTHWEST PACIFIC (SWP) - South Pacific Ocean East of Longitude 160E
NOTE: The tracking and intensity information on Southwest Pacific
Basin tropical cyclones is taken from real-time operational
warnings issued by the Nadi TCWC, Fiji. The MSW 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 or NPMOC, mentioned in the Remarks
column, are 1-min average sustained winds. To convert these
to equivalent 10-min average winds, multiply by 0.87. (Thanks
to Mark Kersemakers for supplying me with some missing points
on Wes and Veli as well as the portion of Ursula's track south
of 25S for which warnings were issued by New Zealand Meteor-
ological Service at Wellington.)
JTWC = Joint Typhoon Warning Center, Guam, Marianas Islands
NPMOC = Naval Pacific Meteorology and Oceanography Center,
located at Pearl Harbor, on the island of Oahu,
Hawaii

NOTE: Winds were not actually mentioned in the discussions. I chose to
use 25 kts (10-min avg) initially since 30 kts would have implied 35 kts
1-min avg. From 13/1800 to 14/1800 gales were forecast for the southern
semi-circle (although according to Mark Kersemakers, it's debatable
whether the gales were there).
