This system did not exist in 1947. The number 194725 is a historical number used by the CMA, and the numbers assigned to the same typhoon that year by JMA (Japan), the Joint Typhoon Warning Center (USA), and China’s meteorological agencies may differ and cannot be directly matched.
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.
