Hurricane Anna
● 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.
Anna at 1956-07-26 02:00:00 (BeijingTime) 在North Atlantic首次被记录, peak intensity 为Cat 1 Hurricane, max wind 约 38.6 m/s (1 分钟平均) , minimum central pressure 991 hPa, at 1956-07-27 20:00:00前后结束, total 记录 8 track points (6 h一个) . 曾Landfall或贴近land.

Data sources: NOAA National Environmental Information Center IBTrACS v04r01 (Knapp et al., 2010), code 1956208N21268 / AL021956. No official Chinese name exists for this basin, so the original English name is used. Intensity is classified by the relevant local agency in the basin, based on 1-minute sustained wind converted using the WMO factor, for reference only. Data notes · Incorrect translation?
