Typhoon Sally, international code 197221, international name SALLY, 1972 Northwest Pacific typhoon. Formed: 1972-11-30 00:00:00, ended: 1972-12-05 00:00:00. Peak intensity: Typhoon , minimum central pressure: 985 hPa, max wind: 41m/s.
Typhoon Sally at 1972-11-30 00:00:00 at 7.4°N, 115.4°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Typhoon intensity with max winds of 41 m/s (~148 km/h) and a minimum central pressure of 985hPa, recorded at 1972-12-02 00:00:00.
Typhoon Sally gradually weakened and was numbered off on 1972-12-05 00:00:00 was numbered off; its lifecycle recorded 21 track points.
Typhoon Sally (197221) formed at SHainan部海域, 整体路径呈现稳定的WNTrend. 从1972年11月30日00:00在(7.4°N, 115.4°E) formedNameless开始, 系统持续 toward NW direction推进. 初期Moving速度较快, During变化显著, 至12月1日06:00到达最S端The latitude6.8°N附近. 随后, 路径出现轻微的 toward N转折, 纬度从6.7°N逐步回升至10°N, 但经度始终保持 toward W递减的Trend, 最终 at 12月5日00:00在(10°N, 99.2°E) weakened into Tropical Storm. 整个生命周期内, 该Typhoon 未Landfall任何陆地, 始终在海上活动, 路径轨迹平滑, 无明显的打转或停滞现象, 主要受引导气流影响横跨S海SW部并 toward 中S半岛以E海域靠近.
Sally的Intensity发展经历了典型的“快速增强-巅峰维持-逐渐减弱”过程. formed初期, 系统在24h内由Nameless迅速 intensified into Severe Tropical Storm, max wind 从12m/s提升至25m/s. 12月1日12:00, 系统进一步发展为Typhoon , wind speed达到38m/s. 12月2日00:00至06:00期间, Typhoon 达到peak intensity, max wind 维持在41m/s. 值得注意的是, 在巅峰状态维持约12h后, 自12月2日12:00起, 中心Max Wind开始下降至35m/s, 并在此后三天内持续减弱. 至12月3日12:00, 系统降级为Severe Tropical Storm, wind speed降至30m/s; Go to 12月4日后, 减弱Trend加速, 最终在生命末期降回Tropical Storm级别, wind speed仅为20m/s. 整个过程显示其在S海暖水域获得了足够的能量支持以达到Typhoon 级Intensity, 但后期可能受环境场变化影响而迅速衰减.
In the sequence of names 'Sally', the 1972 SallyTyphoon Intensity was relatively weak. data showed that its peak intensity was only typhoon level (41m/s) . In comparison, the same-name 1996 Sally (199615) , 1976 Sally (197608) and 1964 Sally (196416) reached Super Typhoon level, showing great destruction potential. even in 1961 Sally (196125) , its peak intensity also reached typhoon level.
