1870North Atlantic未命名Hurricane
● Data reliability: Inferred dataNo satellites or aircraft were available that year, so the record was reconstructed afterward from ships and coastal weather stations. Intensity estimates are approximate for storms before 1950.
未命名 at 1870-09-17 08:00:00 (BeijingTime) 在North Atlantic首次被记录, peak intensity 为Cat 1 Hurricane, max wind 约 41.2 m/s (1 分钟平均) , minimum central pressure 969 hPa, at 1870-09-21 02:00:00前后结束, total 记录 16 track points (6 h一个) .

Data sources: NOAA National Centers for Environmental Information IBTrACS v04r01 (Knapp et al., 2010), code 1870260N30292 / AL051870. There is no official Chinese name for this system, so the English name is used. Intensity is classified according to the local agency in the relevant maritime region, converted from 1-minute sustained wind using the WMO coefficient, for reference only.
