Tropical Cyclone Gertie
● 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.
Gertie at 1971-02-11 08:00:00 (BeijingTime) 在South Pacific首次被记录, peak intensity 为Category 2 Tropical Cyclone , max wind 约 33.4 m/s (1 分钟平均) , at 1971-02-16 14:00:00前后结束, total 记录 22 track points (6 h一个) . 曾Landfall或贴近land.

There is no official Chinese name for this basin, so the original English name is used. Intensity categories follow the classifications of local agencies in the basin, converted from 1-min sustained wind using the WMO scale factor, and are for reference only.
