[Quick Archive Overview]Typhoon HELEN (No.195825, 1981年前的历史序号) is a 1958 Northwest Pacific typhoon; peak intensity Super Typhoon, max wind 85m/s, minimum central pressure 925hPa, 未在我国Landfall, 1958-09-19 was numbered off, 全程记录45 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: The internationally standardized numbering system for the Northwest Pacific has been implemented since 1981 by JMA, the Tokyo Regional Professional Meteorological Centre. This system did not exist in 1958. The number 195825 is a historical identifier retained by the CMA. Numbers assigned that year by JMA, the Joint Typhoon Warning Center in the United States, and China's meteorological authorities may differ for the same typhoon and cannot be compared directly.
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.
