Typhoon Fran Trail Characteristics
Track and Movement Characteristics
Typhoon Fran (197617) 的生命史长达12天, 整体路径呈现典型的NW行后转 toward NE的抛物线形态. formed初期 (9月4日至6日) , 系统位 at 低纬度海域, 受副热带高压S侧引导气流影响, 稳定 toward NW, 纬度从9.4°N迅速N抬至15.9°N, 经度由149.2°EW移至141.8°E. 9月7日至9日期间, Typhoon 维持高Intensity并 toward WNW direction推进, 抵达25.9°N, 129°E附近时达到路径最W端. 随后, 受中纬度W风带槽前气流影响, 路径发生显著转折. 9月10日至11日, 系统在30°N附近近乎停滞并缓慢E移, 完成转 toward 过程. 9月12日后, Typhoon 加速 toward NE, 穿越Japan以S海域, 最终 at 9月16日在42.5°N, 138.2°E weakened into Tropical Depression并结束观测. 全生命周期无Landfall记录, 主要在开阔洋面上活动.
Intensity evolution and historical comparison
Fran’s intensity evolved through three phases: rapid intensification, a period of peak intensity, and gradual weakening. It began as a tropical depression and rapidly intensified into a severe tropical storm within 48 hours. On September 7, the system underwent explosive intensification into a super typhoon near 20°N, with maximum winds reaching 65 m/s and pressure falling to 930 hPa. On September 8, it reached peak intensity, with minimum pressure dropping further to 912 hPa and maximum winds remaining at 65 m/s. It retained super typhoon status for the following two days. Beginning September 10, Fran steadily weakened as it moved northward over cooler waters, successively downgrading to a severe typhoon, a typhoon, and a severe tropical storm. By September 14, after reaching 41.6°N, it had weakened into a tropical storm.
Compared with previous typhoons of the same name, Fran in 1976 was significantly stronger. The 1973 Fran peaked only as a tropical storm, with a central pressure of 1000 hPa. The 1970 Fran reached severe tropical storm status, with a central pressure of 976 hPa, while the 1967 Fran attained typhoon status but had a minimum pressure of 970 hPa. By contrast, the 1976 Fran reached super typhoon status, and its minimum pressure of 912 hPa was far lower than those of the other storms with the same name, demonstrating the system’s exceptional energy accumulation and explosive development.

FAQ
Typhoon Fran was the 1976 Typhoon.
Fran’s number 197617 is the historical number retained by the CMA, meaning the 17th typhoon of 1976. Its international name was FRAN. International typhoon numbering for the Northwest Pacific did not begin until 1981. Before then, agencies maintained separate numbering systems, so the numbers assigned by the JMA in Japan, the Joint Typhoon Warning Center in the USA, and China’s meteorological authorities may differ and cannot be compared directly.
Where does the track data for Typhoon Fran 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 is the highest level of Typhoon Fran?
Typhoon Fran peak intensity is Super Typhoon, max wind 65m/s, minimum central pressure 912 hPa.
Is the Typhoon FranLandfall?
According to records, Typhoon Fran is not in our coastal landfall.
