Tropical Cyclone Angela
● 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.

There is no official Chinese name for this system, so the original English name is used. Intensity categories follow the local agency classification for the region, converted from 1-minute sustained winds using the WMO factor, and are for reference only.
