The SummaryTyphoon Flossie (international code 197515) is a 1975 Northwest Pacific typhoon; peak intensity Typhoon, max wind 35m/s, minimum central pressure 970hPa, not in China Landfall, 1975-10-23 was numbered off, recorded 19 track points.
Typhoon Flossie, international code 197515, international name FLOSSIE, 1975 Northwest Pacific typhoon. Formed: 1975-10-19 00:00:00, ended: 1975-10-23 12:00:00. Peak intensity: Typhoon , minimum central pressure: 970 hPa, max wind: 35m/s.
Typhoon Flossie at 1975-10-19 00:00:00 at 18.4°N, 120.4°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Typhoon intensity with max winds of 35 m/s (~126 km/h) and a minimum central pressure of 970hPa, recorded at 1975-10-22 12:00:00.
1975-10-23 12:00:00 After, Typhoon Flossie gradually weakened and was numbered off on 1975-10-23 12:00:00 was numbered off; its lifecycle recorded 19 track points.
Typhoon Flossie (197515) 的生命史始 at S海E部海域, 整体路径呈现显著的NW toward MovingTrend. formed初期 (10月19日00时至20日06时) , 系统位 at lat 15°至18°N, 116°至120°之间, 主要 toward WSW direction缓慢Moving, The latitude从18.4°N降至15.3°N, During由120.4°EW移至116°E. 10月20日12时左右, 路径出现明显转折, 系统StopS压并开始转 toward NW direction行进. 此后, Typhoon 中心稳定沿NW路径穿Vietnam海N部, 直至10月23日12时消散 at lat 21.8°N, 109.4°附近. 全生命周期内, 该Typhoon 未Landfall任何陆地, 始终在海上活动, track pointstotal 计19个, Moving轨迹相对平滑, 无剧烈摆动或异常回旋现象.
该系统经历了完整的“ formed-加强-巅峰-减弱”过程. 初始阶段为Nameless, max wind 维持在12-15m/s. 10月20日18时, wind speed增至20m/s, 升级为Tropical Storm; 随后Intensity稳步提升, at 10月21日12时达到Severe Tropical Storm级别 (25m/s) . 加速增强期出现在10月22日凌晨至中午, wind speed从30m/s迅速攀升至峰值35m/s, 并 at 10月22日12时正式达到Typhoon 级别. 巅峰状态维持约12h, 期间中心位 at lat 19°至19.7°之间. 10月23日00时起, 系统Go to 快速减弱阶段, wind speed由33m/s骤降至15m/s, 仅用12h便由Typhoon 级退化为Nameless, 最终消散. 值得注意的是, 数据中最低气压字段缺失, 仅能依据wind speed判断Intensity变化.
Looking back at the typhoon, which was previously called 'Flossie', this process in 1975 was above the intensity at a medium level. Compared with the 1972 (197212) and 1964 (196408) two times reached the typhoon level system of the same name, Flossie's peak wind speed (35m/s) in 1975 was in line with the typhoon standard, but the lack of air pressure data supported a more detailed intensity ranking. Compared with the 1969 (Severe Tropical Storm) and 1961 (Tropical Storm), Flossie's intensity in 1975 was significantly stronger, showing a more complete tropical cycle development structure.
