Tropical Cyclone Jacqueline
● 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 1978043S16072 / SH191978. There is no official Chinese name for this system, so the original English name is used. Intensity is classified by the local agency for the region, converted from 1-minute sustained winds using the WMO factor, and is for reference only. Data notes · Incorrect translation?
