[Quick Archive Overview]Typhoon Ida (No. 197518, a historical number used before 1981) was a 1975 Northwest Pacific typhoon. It peaked as a typhoon, with maximum winds of 40 m/s and a minimum central pressure of 950 hPa. It did not make landfall in China and was designated dissipated on November 13, 1975, with 28 track points recorded throughout its lifetime.
Numbering notes: International numbering in the Northwest Pacific is assigned by the JMA, the Regional Specialized Meteorological Center for East Asia, beginning in 1981. This system did not exist in 1975. The number 197518 is the historical number retained by the CMA. The numbers assigned that year by the JMA, the Joint Typhoon Warning Center in the United States, and China’s meteorological authorities may differ for the same typhoon and therefore cannot be compared directly.
