Unnamed North Indian Ocean cyclone of 1972
● 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 1972098N09091 / IO011972. No official Chinese name exists for this system, so the English name is shown. The intensity category follows the local agency classification for the basin, converted from 1-min sustained wind using the WMO factor, and is for reference only. Data notes · Incorrect translation?
