1956South Indian Ocean未命名Tropical Cyclone
● 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.
未命名 at 1956-08-27 02:00:00 (BeijingTime) 在South Indian Ocean首次被记录, peak intensity 为Tropical Depression, max wind 约 15.4 m/s (1 分钟平均) , at 1956-08-30 20:00:00前后结束, total 记录 16 track points (6 h一个) . 曾Landfall或贴近land.

Data source: NOAA National Centers for Environmental Information IBTrACS v04r01 (Knapp et al., 2010), code 1956240S11098 / SH011957. This basin has no official Chinese name, so the original English name is used. Intensity grades follow the classification by the local agency in the region, converted from 1-minute sustained winds using the WMO factor, and are for reference only.
