Typhoon Chaba, international code 200417, international name CHABA, 2004 Northwest Pacific typhoon. Formed: 2004-08-20 14:00:00, ended: 2004-08-31 20:00:00. Peak intensity: Super Typhoon, minimum central pressure: 910 hPa, max wind: 65m/s.
Typhoon Chaba at 2004-08-20 14:00:00 at 13.8°N, 157°E over the Northwest Pacific; initial intensity: Tropical Storm.
It peaked at Super Typhoon intensity with max winds of 65 m/s (~234 km/h) and a minimum central pressure of 910hPa, recorded at 2004-08-23 14:00:00.
2004-08-31 20:00:00 After, Typhoon Chaba gradually weakened and was numbered off on 2004-08-31 20:00:00 was numbered off; its lifecycle recorded 75 track points.
Typhoon Chaba (200417) 的生命史始 at Northwest Pacific远洋海域, 整体路径呈现典型的“W行—NW行—转 toward NE”的抛物线形态. formed初期 (8月20日至22日) , 系统稳定 toward WMoving, The latitude维持在13.8°N至14.4°N之间, During从157°E快速W移至146.3°E, 显示出稳定的引导气流作用. 8月23日起, 路径逐渐转为NW direction, 纬度开始显著N抬, 从14.9°N升至18.5°N.
关键的转 toward 过程发生在8月24日至26日期间. 虽然此阶段Intensity维持巅峰, 但Moving direction由NW逐渐过渡为N, 随后在8月27日后明显转 toward NE. 8月30日, Center到达34.1°N, 131.8°E, 标志着其完全Go to 中高The latitudeW风带控制区. 最终 at 8月31日消散 at 46.7°N, 145.7°E的远海区域. 整个生命周期长达11天, track points多达75个, 且全程无Landfall记录, 属 at 典型的远洋长寿命Typhoon .
From Tropical Storm (20m/s) to Super Typhoon only in about 3 days, minimum pressure rapidly drops to below 925hPa. From August 23, 14 to August 27, 20, the systemins Super Typhoon intensity with max winds of 55-65m/s for up to 4 days, minimum pressure stable in the range of 910-915hPa, of which August 24, 20 reaches the minimum atmospheric pressure of 910hPa, Max Wind65m/s peak state. This long Timeins extremely high intensity characteristics is more rare in Northwest Pacific Typhoon.
Chaba peaked only at Typhoon level (965hPa) in 2022, Chaba at Severe Typhoon level (940hPa) in 2010, although Chaba's lowest air pressure (910hPa) in 2004 was lower than Chaba's lowest air pressure (920hPa) in 2016, which also reached Super Typhoon level (920hPa), and max wind greater (65m/s vs. not specifically given but usually 920hPa corresponds to wind speed slightly lower or equivalent), showing that the 2004 system has a deeper correlation core and stronger energy reserves.
