Typhoon Nancy, international code 197001, international name NANCY, 1970 Northwest Pacific typhoon. Formed: 1970-02-20 00:00:00, ended: 1970-02-27 12:00:00. Peak intensity: Super Typhoon, minimum central pressure: 950 hPa, max wind: 61m/s.
Typhoon Nancy at 1970-02-20 00:00:00 at 8.6°N, 149.1°E over the Northwest Pacific; initial intensity: Tropical Storm.
It peaked at Super Typhoon intensity with max winds of 61 m/s (~220 km/h) and a minimum central pressure of 950hPa, recorded at 1970-02-24 00:00:00.
1970-02-27 12:00:00 After, Typhoon Nancy gradually weakened and was numbered off on 1970-02-27 12:00:00 was numbered off; its lifecycle recorded 31 track points.
Typhoon Nancy (197001) formed at Northwest Pacific低The latitude海域, 初始Position位 at 8.6°N, 149.1°E. 在生命史初期, 系统呈现明显的W行Trend, 从2月20日至2月24日, 其During由149.1°E快速W移至131.2°E, 纬度维持在8°N至10°N之间小幅波动, 表明其主要受低层信风引导, Moving路径平直且稳定. 2月24日00:00达到最W端后, 路径出现显著转折. 自2月24日12:00起, Typhoon 中心开始 toward NW, 随后逐渐转为N乃至NE direction. 至2月27日消散前, Center已N抬至21.4°N, E退至126.8°E. 整体路径呈现典型的“W行-NW转N-NE”的抛物线型特征, 转 toward 点大致位 at 131°E附近. 全生命周期内无Landfall记录, 始终在洋面上活动.
该Typhoon Intensity演变迅速且峰值极高. 从2月20日的Tropical Storm (20m/s) 起步, 仅用时约54h便增强为Typhoon (41m/s) , 并在2月23日00:00进一步发展为Super Typhoon (51m/s) . 2月24日00:00, Nancy达到peak intensity, max wind 录得61m/s, 维持Super Typhoon等级长达近3天 (2月23日00:00至2月25日12:00) . 此后, 随着The latitude升高及环境场变化, intensity 开始减弱, 2月26日00:00降为Severe Typhoon, 最终 at 2月27日12:00 weakened into Nameless并结束监测.
与同名History相比, 1970年Nancy的Intensity表现尤为突出. 相较 at 1989年, 1986年及1979年的同名Typhoon (peak intensity分别为Typhoon , Typhoon , Tropical Storm) , 1970年Nancy达到了Super Typhoon级别. 虽然1982年Nancy (198221) 也达到了Super Typhoon级别, 但1970年Nancy以61m/s的极大wind speed展现了极强的破坏潜力. 其快速增强过程及长Time维持超高Intensity的特征, 使其在同期Typhoon 中具备显著的极端性.
