Tropical Cyclone Aurore
● 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.
Aurore at 1977-11-18 14:00:00 (BeijingTime) 在South Indian Ocean首次被记录, peak intensity 为Severe Tropical Cyclone , max wind 约 50.9 m/s (1 分钟平均) , minimum central pressure 927 hPa, at 1977-11-29 14:00:00前后结束, total 记录 45 track points (6 h一个) .

There is no official Chinese name for this area, so the original English name is used. Intensity grades follow the classifications of the local agency in the relevant sea area (converted from 1-minute sustained winds using the WMO factor) and are for reference only.
