[Quick Archive Overview]Typhoon PHYLLIS (No.197505, a historical sequence number used before 1981) was a 1975 Northwest Pacific typhoon. It peaked as a super typhoon, with maximum winds of 60 m/s and a minimum central pressure of 931 hPa. It did not make landfall in China, was numbered off on 1975-08-19, and has 29 recorded track points.
Numbering note: International numbering in the Northwest Pacific is assigned by the JMA in Japan, the Tokyo Regional Specialized Meteorological Center, beginning in 1981. This system did not exist in 1975. The number 197505 is the historical sequence number retained by the CMA. Before 1981, the JMA, the Joint Typhoon Warning Center in the United States, and China’s meteorological authorities could assign different numbers to the same typhoon, so the numbers cannot be compared directly.
