Analysis of Typhoon Shirley's Track Characteristics
Track and Turning Characteristics
Typhoon Shirley (196518) 的生命周期始 at Northwest Pacific低纬度海域, 整体路径呈现典型的“抛物线”型Moving特征. formed初期 (9月1日至5日) , 系统在8.6°N至17.2°N之间缓慢 toward NW, 经度从145.4°EW移至140.8°E后略有E折, 显示其在副热带高压S侧受引导气流影响较为稳定. 9月6日至9日期间, 随着纬度N抬至20°N以上, 系统加速 toward WNW direction行进, 并 at 9月7日左右在22°N, 138.8°E附近完成关键的转 toward 动作, 路径由NW转为NE direction. 此后, Typhoon 沿Japan以E海域快速 toward NE, 直至Go to 高纬度W风带. 整个过程中, 该系统未Landfall任何land, 始终在洋面上活动, 最终 at 9月13日在51.5°N, 179.9°E附近减弱消散, 全生命周期长达12天半, 路径跨度极大, 从热带延伸至副极地海域.
Intensity evolution and historical comparison
Shirley underwent a long period of development followed by a rapid intensification phase. During the tropical depression stage from September 1 to 5, its central pressure remained at 1004–1006 hPa, with little change in intensity. After upgrading to a tropical storm on September 6, the system entered a rapid intensification phase: within 48 hours, its wind speed surged from 20 m/s to 50 m/s, while its central pressure dropped sharply to 953 hPa. It reached super typhoon intensity on September 9 and peaked near 31.5°N, 133°E on September 10, with maximum winds of 70 m/s and a minimum central pressure of 936 hPa. Notably, it maintained super typhoon intensity despite its relatively high latitude of 31.5°N, indicating tremendous energy reserves. After its peak, the system weakened rapidly under the influence of cold high-latitude waters and vertical wind shear, with wind speeds halving within 48 hours. It then became a severe tropical storm before transitioning into the precursor of a temperate cyclone.
Compared with previous typhoons bearing the same name, the 1965 Shirley was significantly more intense than the 1978 tropical storm, the 1968 typhoon, and the 1974 severe typhoon of the same name. Its peak central pressure of 936 hPa was very close to the 935 hPa recorded by Shirley in 1963. Both were among the most intense typhoons historically bearing the name Shirley, demonstrating the occasional extreme severity associated with this naming series.

FAQ
Shirley was the 1965 Typhoon.
196518 is the historical identifier used by the CMA for Typhoon Shirley, meaning the 18th typhoon of 1965. Its international name was SHIRLEY. International numbering for Northwest Pacific typhoons did not begin until 1981. Before then, each agency used its own numbering system, so the identifiers assigned by the JMA in Japan, the Joint Typhoon Warning Center in the United States, and Chinese meteorological authorities may differ for the same typhoon and cannot be directly compared.
Where does the track data for Typhoon Shirley come from?
Track data sources: China Meteorological Administration Tropical Cyclone Best Track Dataset (CMA-STI); wind speeds are 2-minute sustained wind speeds.
What was the peak intensity level of Typhoon Shirley?
Typhoon Shirley peak intensity is Super Typhoon, max wind 70m/s, minimum central pressure 936 hPa.
Did Typhoon Shirley make landfall?
According to records, Typhoon Shirley did not make landfall on China's coast.
