[Quick Archive Overview]Typhoon No. 4 (No.194704, historical sequence number used before 1981) was a 1947 Northwest Pacific typhoon; peak intensity: tropical depression, max wind 17m/s, minimum central pressure -hPa, did not make landfall in China, numbered off on 1947-07-09, with 6 track points recorded throughout.
Code notes: In the Northwest Pacific, the internationally standardized code has been assigned since 1981 by JMA (Japan), the Tokyo Regional Professional Meteorological Centre. This system did not exist in 1947; 194704 is the historical sequence number used by the CMA. JMA (Japan), the Joint Typhoon Warning Center of the USA, and Chinese meteorological authorities may have assigned different sequence numbers to the same typhoon that year, so they cannot be directly compared.
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.
