Tropical Cyclone Lance
● 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).
Lance at 1984-04-03 08:00:00 (BeijingTime) 在South Pacific首次被记录, peak intensity 为Category 1 Tropical Cyclone , max wind 约 20.6 m/s (1 分钟平均) , minimum central pressure 992 hPa, at 1984-04-10 02:00:00前后结束, total 记录 28 track points (6 h一个) .

Data sources: NOAA National Environmental Information Center IBTrACS v04r01 (Knapp et al., 2010), code 1984094S14156 / SH311984. This area has no official Chinese name, so the original English name is used. Intensity categories follow the classifications of the local agency in the region (converted from 1-min sustained wind using the WMO factor) and are for reference only.
