[Quick Archive Overview]Typhoon IRIS (historical identifier No. 195519, used before 1981) was a 1955 Northwest Pacific typhoon. Its peak intensity was severe typhoon, with maximum winds of 45 m/s and a minimum central pressure of 965 hPa. It did not make landfall in China. It was designated No. 19 on August 25, 1955, with 27 track points recorded throughout its lifetime.
Identifier notes: International cyclone identifiers for the Northwest Pacific have been assigned by the JMA in Japan, the regional specialized meteorological center for East Asia, since 1981. This system did not exist in 1955. The identifier 195519 is a historical number retained by the CMA. The JMA in Japan, the Joint Typhoon Warning Center in the United States, and China's meteorological agencies may have assigned different numbers to the same typhoon that year, so they cannot be compared directly.
