[Quick Archive Overview]Typhoon Iris (No.195903, the pre-1981 historical number) was a 1959 Northwest Pacific typhoon. It peaked as a severe typhoon, with maximum winds of 50m/s and a minimum central pressure of 965hPa. It did not make landfall in China and was numbered off on 1959-08-23, with 19 track points recorded throughout its lifetime.
Code explanation: The internationally unified numbering system for the Northwest Pacific has been assigned by JMA (Japan), the E-region specialized meteorological center, since 1981. This system did not exist in 1959. 195903 is the historical number continued by the CMA, and the numbers assigned that year by JMA (Japan), the USA Joint Typhoon Warning Center, and China's meteorological authorities may differ and cannot be directly compared.
