[Quick Archive Overview]Typhoon OLGA (No.194820, historical numbering before 1981) was a 1948 Northwest Pacific typhoon; peak intensity: severe tropical storm, maximum wind: 28 m/s, minimum central pressure: -hPa, did not make landfall in China, final advisory on 1948-10-19, with 14 track points recorded throughout its lifetime.
Code explanation: International uniform numbering in the Northwest Pacific has been assigned by JMA (Japan), the Regional Specialized Meteorological Center for East Asia, since 1981. This system did not exist in 1948. 194820 is the historical number retained by the CMA. The numbers assigned that year by JMA (Japan), the Joint Typhoon Warning Center (USA), and China's meteorological authorities may differ for the same typhoon and cannot be directly compared.
Track data source: USA Joint Typhoon Warning Center (JTWC) best-track data. China Meteorological Administration best-track dataset begins in 1949 and does not include this typhoon. JTWC wind speeds are 1-min sustained wind speeds, generally about 10% higher than the 2-min sustained wind speeds used in China.
