Tropical Cyclone Donaline
● Data reliability: ReliableWeather satellites monitored it throughout, so its track and intensity are relatively accurate (Atlantic and E. Pacific since 1966, other basins since 1980).
Donaline at 1998-03-04 20:00:00 (BeijingTime) 在South Indian Ocean首次被记录, peak intensity 为Severe Tropical Storm, max wind 约 28.3 m/s (1 分钟平均) , minimum central pressure 988 hPa, at 1998-03-12 14:00:00前后结束, total 记录 32 track points (6 h一个) .
