Unnamed North Indian Ocean cyclone of 1998
● 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).
未命名 at 1998-10-26 20:00:00 (BeijingTime) 在North Indian Ocean首次被记录, peak intensity 为Depressions, max wind 约 15.9 m/s (1 分钟平均) , minimum central pressure 1002 hPa, at 1998-10-29 14:00:00前后结束, total 记录 12 track points (6 h一个) .

Data source: NOAA National Environmental Information Center IBTrACS v04r01 (Knapp et al., 2010), code 1998299N11090. There is no official Chinese translated name for this system, so the original English name is used. Intensity is classified by the local agency for the relevant sea area, based on 1-min sustained wind converted using the WMO factor, for reference only. Data notes · Incorrect translation?
