[Quick Archive Overview]Typhoon ANNA (No.194701, the historical number used before 1981) was a 1947 Northwest Pacific typhoon. Its peak intensity was tropical depression, with maximum winds of 17m/s and minimum central pressure of -hPa. It did not make landfall in China and was decommissioned on 1947-03-20. The full track contains 6 track points.
Numbering system: The internationally unified numbering system for the Northwest Pacific has been assigned by the JMA (Japan), the Ejing regional specialized meteorological center, since 1981. This system did not exist in 1947. The 194701 is the historical number still used by the CMA. The JMA (Japan), Joint Typhoon Warning Center in the USA, and Chinese meteorological agencies 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.
