Tropical Cyclone Emma
● Data reliability: Generally reliable——Aircraft entered typhoons for in situ measurements, but satellites were not yet widespread: tracks are generally accurate, while intensities may be biased, with weaker cyclones potentially going unrecorded from 1950 until the advent of satellite coverage.
Emma at 1970-02-27 14:00:00 (BeijingTime) 在South Pacific首次被记录, peak intensity 为3级Tropical Cyclone , max wind 约 38.6 m/s (1 分钟平均) , minimum central pressure 965 hPa, at 1970-03-06 08:00:00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 1970058S15200 / SH201970. There is no official Chinese name for this system, so the original English name is used. Intensity categories follow the classifications of the local agency in the region where it occurred (converted from 1-minute sustained wind using the WMO factor), for reference only.
