[Quick Archive Overview]Typhoon THELMA (No.195604, 1981年前的历史序号) is a 1956 Northwest Pacific typhoon; peak intensity Super Typhoon, max wind 75m/s, minimum central pressure 935hPa, 未在我国Landfall, 1956-04-25 was numbered off, 全程记录36 track points. (注: 1970年代以前的Typhoon Intensity主要依靠飞机侦察和船舶报告估算, wind speed记录普遍偏高, 此为China气象局最佳路径原始值, 与现代卫星时代数据不宜直接比较. )
Numbering note: international cyclone numbers for the Northwest Pacific have been assigned since 1981 by JMA in Japan, the Regional Specialized Meteorological Center for East Asia. This system did not exist in 1956, when 195604 was the historical number retained by the CMA. The numbers assigned that year by JMA in Japan, the Joint Typhoon Warning Center in the United States, and China’s meteorological agencies may differ and cannot be directly compared.
Path. Data sources: China Meteorological Administration Tropical Cyclone Best Track Dataset (CMA-STI); wind speed refers to 2-min sustained wind speed. Track points at intermediate times are encrypted based on original operational positioning data, while wind speed and pressure are interpolated using best-track anchor points.

FAQ
Which numbered typhoon of 1956 was Typhoon THELMA?
THELMA’s 195604 is the historical number retained by the CMA, meaning the fourth typhoon of 1956, while its international name was THELMA. International cyclone numbering for the Northwest Pacific did not begin until 1981. Before then, each agency used its own numbering system, so the numbers assigned by JMA in Japan, the Joint Typhoon Warning Center in the United States, and China’s meteorological agencies may differ and cannot be directly compared.
Where does the track data for Typhoon THELMA come from?
Path. Data sources: China Meteorological Administration Tropical Cyclone Best Track Dataset (CMA-STI); wind speed refers to 2-min sustained wind speed. Track points at intermediate times are encrypted based on original operational positioning data, while wind speed and pressure are interpolated using best-track anchor points.
What was the peak intensity of Typhoon THELMA?
Typhoon THELMA peak intensity is Super Typhoon, max wind 75m/s, minimum central pressure 935 hPa.
Did Typhoon THELMA make landfall?
According to historical records, Typhoon THELMA did not make landfall on China’s coast.
