Typhoon Sarah, international code 197320, international name SARAH, 1973 Northwest Pacific typhoon. Formed: 1973-11-09 00:00:00, ended: 1973-11-12 06:00:00. Peak intensity: Severe Tropical Storm, minimum central pressure: 985 hPa, max wind: 28m/s.
Typhoon Sarah at 1973-11-09 00:00:00 at 11.9°N, 115.8°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Severe Tropical Storm intensity with max winds of 28 m/s (~101 km/h) and a minimum central pressure of 985hPa, recorded at 1973-11-10 12:00:00.
1973-11-12 06:00:00 After, Typhoon Sarah gradually weakened and was numbered off on 1973-11-12 06:00:00 was numbered off; its lifecycle recorded 14 track points.
Typhoon Sarah (197320) 的生命史短暂且路径清晰, 整体呈现稳定的W行Trend. 系统 at 1973年11月9日00时在S海中部海域 (11.9°N, 115.8°E) formed, 初始状态为Nameless. 在随后的36h内, Typhoon 主体维持 toward WN, The latitude从11.9°N缓慢爬升至12.5°N, During则从115.8°E快速W移至108.5°E, 平均移速较快. 值得注意的是, 系统在11月10日12时达到最N端纬度12.4°N-12.5°N区间后, 路径出现轻微转折, 随后转为 toward SW. 这种先WN, 后转SW的路径形态, 表明其受到特定引导气流的影响, 未发生典型的N上转 toward 或Landfall行为, 最终 at 11月12日06时在10°N, 100.3°E附近消散, 全程无Landfall记录.
在Intensity变化方面, Sarah经历了“增强-巅峰-迅速减弱”的典型过程. formed初期Intensity维持在12-17m/s的Nameless级别. 11月10日00时, 系统 intensified into Tropical Storm (20m/s) , 并 at 同日06时进一步发展为Severe Tropical Storm, wind speed达到25m/s. 11月10日12时, Typhoon 达到生命史中的peak intensity, max wind 录得28m/s, 定性为Severe Tropical Storm. 然而, 巅峰状态极为短暂, 仅维持6h后, 至11月10日18时, wind speed骤降至17m/s, 重新跌回Nameless等级. 此后直至消散, intensity 始终维持在12-15m/s的低位震荡, 显示其结构在达到巅峰后迅速瓦解.
Data show that in 1989 the same name Typhoon had reached the level of Super Typhoon, in 1986 also Severe Tropical Storm, and in 1973 Sarah although the same as Severe Tropical Storm, but its Max Wind (28m/s) is low at 1989 system, and the life cycle is short. compared to at 1983 and 1979 Tropical Storm level of the same name Typhoon, in 1973 Sarah overcomes the peak intensity, but given its lack of pressure data support and rapid weakening, the overall destruction potential is limited, belonging to the typical short-lived, medium-intensity thermal cycling process at S seas.
