1954North Atlantic未命名Hurricane
● 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.

Data sources: NOAA National Centers for Environmental Information IBTrACS v04r01 (Knapp et al., 2010), code 1954259N26271 / AL111954. This system has no official Chinese name, so the English original is used. Intensity is classified by the local agency in the relevant ocean basin, converted from 1-minute sustained winds using the WMO factor, and is for reference only. Data notes · Incorrect translation?
