Numbering explanation: International numbering in the Northwest Pacific has been assigned by the JMA in Japan, the regional specialized meteorological center for East Asia, since 1981. This system did not exist in 1974. The number 197409 is the historical number continued by the CMA. The numbers assigned that year by the JMA in Japan, the Joint Typhoon Warning Center in the United States, and China's meteorological agencies may differ and cannot be compared directly.
