Tropical Cyclone Irene
● Data reliability: ReliableWeather satellites monitored it throughout, so its track and intensity are relatively accurate (Atlantic and E. Pacific since 1966, other basins since 1980).
Irene at 2023-01-15 20:00:00 (BeijingTime) 在South Pacific首次被记录, peak intensity 为Category 2 Tropical Cyclone , max wind 约 28.3 m/s (1 分钟平均) , minimum central pressure 980 hPa, at 2023-01-20 14:00:00前后结束, total 记录 20 track points (6 h一个) .

There is no official Chinese name for this system, so the original English name is used. Intensity is classified by the local agency in the relevant basin, converted from 1-min sustained wind using the WMO factor, for reference only. Data notes · Incorrect translation?
