Tropical Cyclone Jane
● 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 grades follow the classifications of the relevant local agencies in the basin, converted from 1-min sustained wind using the WMO factor, and are for reference only.
