Typhoon Namtheum, international code 200410, international name NAMTHEUM, 2004年Northwest PacificTyphoon . formedTime: 2004-07-25 20:00:00, 结束Time: 2004-08-01 02:00:00. peak intensity: Severe Typhoon, 最低Pressure: 945 hPa, max wind : 50m/s.
Typhoon Namtheum at 2004-07-25 20:00:00 at 23.6°, lng 149.3° over the Northwest Pacific; initial intensity: Tropical Storm.
It peaked at Severe Typhoon intensity with max winds of 50 m/s (~180 km/h) and a minimum central pressure of 945hPa, recorded at 2004-07-27 02:00:00.
2004-08-01 02:00:00 After, Typhoon Namtheum gradually weakened and was numbered off on 2004-08-01 02:00:00 was numbered off; its lifecycle recorded 26 track points.
Typhoon Namtheum (200410) 的生命史始 at Northwest Pacific洋面, 整体路径呈现典型的“NW行转NE”的抛物线形态. formed初期 (7月25日20时) , 系统位 at 23.6°N, 149.3°E, 随后稳定 toward NW. 在7月25日至7月28日期间, Typhoon 中心The latitude从23.6°N迅速N抬至31.4°N, During由149.3°EW进至140.8°E, 显示出较强的NW toward 引导气流作用.
路径的关键转折点出现在7月29日前后. 数据显示, 7月29日08时至20时, Typhoon 中心The latitude维持在31.5°N不变, 而During继续W移, 表明此时系统处 at 转 toward 前的停滞或缓慢调整期. 随后, 自7月30日08时起, 路径明显转为NE direction, 纬度持续N抬直至35.2°N, 经度则 toward E回撤至130.7°E附近. 整个过程中, Typhoon 未Landfall任何陆地, 始终在海上活动, 最终在高纬度海域减弱消散.
Namtheum的Intensity变化经历了“快速增强—巅峰维持—逐渐减弱”三个阶段. 从7月25日20时的Tropical Storm (20m/s, 995hPa) 起步, 系统在不到48h内急剧加强. 至7月26日20时, 已升级为Severe Typhoon (45m/s, 950hPa) ; 7月27日08时达到生命史巅峰, 中心最低气压降至945hPa°E, max wind 达50m/s, 确认为Severe Typhoon级别. 巅峰状态维持约12h后, 自7月27日20时起开始缓慢减弱, 气压回升, wind speed下降. Go to 8月后, 随着The latitude升高, 系统进一步 weakened into Tropical Storm.
Compared to the same name History, 2004 Namtheum's Intensity was significantly higher at most years. 2021 Namtheum (202119) and 2010 Namtheum (201008) peaked only for Tropical Storm, minimum pressure is 995hPa, far weak at 2004 individuals. It is worth noting that 2016 Namtheum (201612) also reached Severe Typhoon level, minimum pressure is also 945hPa, with 2004 Namtheum's peak intensity equal.
