Typhoon Prapiroon, international code 201221, international name Prapiroon, 2012年Northwest PacificTyphoon . formedTime: 2012-10-07 20:00:00, 结束Time: 2012-10-18 02:00:00. peak intensity: Severe Typhoon, 最低Pressure: 940 hPa, max wind : 48m/s.
Typhoon Prapiroon at 2012-10-07 20:00:00 at 17.8°, lng 136.6° over the Northwest Pacific; initial intensity: Tropical Storm.
It peaked at Severe Typhoon intensity with max winds of 48 m/s (~173 km/h) and a minimum central pressure of 940hPa, recorded at 2012-10-12 08:00:00.
Typhoon Prapiroon gradually weakened and was numbered off on 2012-10-18 02:00:00 was numbered off; its lifecycle recorded 76 track points.
Typhoon Prapiroon (201221) 的生命史始 at Northwest Pacific远洋海域, 整体路径呈现典型的“W行—N折—NE转 toward ”的抛物线形态. formed初期 (10月7日至10日) , 系统稳定 toward WMoving, The latitude基本维持在17.8°N至18.8°N之间, During从136.6°E快速W移至129.7°E. 10月11日至12日期间, 路径出现轻微N翘并伴随经度回撤 (从128.4°E移至128.8°E) , 显示引导气流发生微妙变化. 随后, Typhoon Go to 转 toward 阶段, 自10月13日起持续 toward NE, 直至10月18日消散 at 26.2°N, 130.4°E附近. 全生命周期长达10天以上, 途经76 track points, 但始终在海上活动, 无Landfall记录, 属 at 典型的远洋型Typhoon .
该Typhoon 经历了完整的“增强—巅峰—减弱”过程. 初始为Tropical Storm (18m/s) , 在W行过程中迅速加强, 10月10日凌晨升级为Typhoon , 当晚即达到Severe Typhoon级别. 10月12日11时, Prapiroon达到生命史巅峰, 中心最低气压降至940hPa°E, max wind 达48m/s, 维持Severe TyphoonIntensity. 巅峰期后, 随着路径N折, 环境条件转差, intensity 开始波动下滑. 10月13日至15日期间, intensity 在Typhoon 与Severe Typhoon之间震荡 (wind speed40-42m/s, 气压950-955hPa) . 10月16日后, 受高The latitude冷空气或风切变影响, intensity 显著衰减, 迅速降格为Severe Tropical Storm, 最终在N上过程中逐渐消亡.
It peaked at Severe Typhoon level (940hPa, 48m/s) , far beyond the typhoon level peak of 2018 (201807) (970hPa) . Although 2000 Prapiroon (200012) lacks specific air pressure data, but only in terms of existing data, 2012 Prapiroon showed a deeper corrosion core and a stronger wind force structure, being one of the strongest "Prapiroon" in recent decades.
