[Quick Archive Overview]Typhoon ALLYN (No.194931, a historical number from before 1981) was a 1949 Northwest Pacific typhoon; peak intensity Severe Typhoon, max wind 50m/s, minimum central pressure 960hPa, it did not make landfall in China, it was numbered off on 1949-11-25, and 46 track points were recorded throughout its life.
Code explanation: The international unified code for the Northwest Pacific is assigned by JMA (Japan) (the E-region specialized meteorological center) from 1981 onward. In 1949 this system did not exist; 194931 is the historical number kept by CMA. JMA (Japan), the Joint Typhoon Warning Center in the USA, and China's meteorological authorities may have assigned different numbers to the same typhoon back then, so they cannot be compared directly.
