[Quick Archive Overview]Typhoon ANN (No.194501, a historical number used before 1981) was a 1945 Northwest Pacific typhoon. Its peak intensity was severe tropical storm, with maximum winds of 25 m/s and minimum central pressure of -hPa. It did not make landfall in China. It was numbered off on 1945-04-26, with 29 track points recorded throughout its lifetime.
Numbering explanation: The unified international numbering system for the Northwest Pacific was introduced by the JMA (Japan), the regional specialized meteorological center for East Asia, in 1981. This system did not exist in 1945. The number 194501 is a historical number retained by the CMA. The JMA (Japan), the Joint Typhoon Warning Center (USA), and China's meteorological authorities may have assigned different numbers to the same typhoon that year, so these numbers cannot be compared directly.
Track data source: USA Joint Typhoon Warning Center (JTWC) best-track data. China Meteorological Administration best-track dataset begins in 1949 and does not include this typhoon. JTWC wind speeds are 1-min sustained wind speeds, generally about 10% higher than the 2-min sustained wind speeds used in China.

FAQ
Which numbered typhoon of 1945 was Typhoon ANN?
Typhoon ANN's number 194501 is the historical number retained by the CMA (the first typhoon of 1945), with ANN as its international name. The unified international numbering system for the Northwest Pacific did not begin until 1981. Before that, each agency used its own numbering: the JMA (Japan), the Joint Typhoon Warning Center (USA), and China's meteorological authorities may have assigned different numbers to the same typhoon, so these numbers cannot be compared directly.
Where does the track data for Typhoon ANN come from?
Track data source: USA Joint Typhoon Warning Center (JTWC) best-track data. China Meteorological Administration best-track dataset begins in 1949 and does not include this typhoon. JTWC wind speeds are 1-min sustained wind speeds, generally about 10% higher than the 2-min sustained wind speeds used in China.
What was the maximum intensity of Typhoon ANN?
Typhoon ANN peak intensity is Severe Tropical Storm, max wind 25m/s, minimum central pressure - hPa.
Did Typhoon ANN make landfall?
According to the records, Typhoon ANN did not make landfall along China's coast.
