Typhoon Chebi's final best-track value differs from its live value. The live value reflects operational data during the typhoon's active period. After Typhoon Chebi ended, the CMA used more complete observational data to produce final best-track data, which is generally used for academic research and historical rankings. Data sources: CMA Tropical Cyclone Best Track Dataset (compiled using IBTrACS v04r01); wind speed converted from knots to m/s and rounded.
Characteristics of Typhoon Chebi
Track Movement and Recurvature Characteristics
The life cycle of Typhoon Chebi (202417) began over the open waters of the northwest Pacific, and its overall track showed a pronounced trend toward the NNE. From its initial position at (18.2°N, 145°E) to its final position at (38°N, 144.4°E), the system remained at sea throughout, with no recorded landfall. In terms of movement, from September 27 to 28, the system initially moved slowly toward the NW, with its latitude increasing from 18.2°N to 20.9°N and its longitude shifting westward by about 2.7 degrees, indicating guidance by flow along the southern side of the subtropical high.
Go to September 29th, the path showed a noticeable shift. As the latitude broke 22°N, the system gradually turned to positive N, and accelerated toward NE direction between September 30th and October 1st. Especially between September 30th, 14:00 and October 1st, 08:00, the latitude jumped rapidly from 27.6°N to 32.6°N within 18h, indicating its Go to the W wind zone front zone, Moving speed significantly accelerated. Ultimately, the system reached the high latitude area near 38°N on October 1st, 23:00 and ended observations, the path shape showed a typical “push line” toward shift characteristic, but there was no sharp halt or stagnation phenomenon.
Intensity evolution and historical comparison
在Intensity变化上, “Chebi”表现出缓慢增强且后期趋 at 稳定的特点. formed初期至9月29日上午, Pressure维持在998hPa, max wind 保持18m/s的Tropical Storm等级. 9月29日20:00起, 系统开始微弱加强, 气压降至995hPa, wind speed增至20m/s. 随后在9月30日, 气压进一步下降至990hPa, wind speed提升至23m/s. 直至10月1日08:00, 系统达到peak intensity, 定为Severe Tropical Storm, 中心The minimum air pressure.为985hPa, max wind 25m/s. 此后直至生命史结束, intensity 未再发生显著变化, 保持在巅峰状态.
In comparison with previously the same name Typhoon, 2024 'Chebi' Intensity is clearly weak. 2018 21st Typhoon 'Chebi' has developed into Super Typhoon, minimum pressure to 905hPa; 2001 2nd Typhoon 'Chebi' also reached Super Typhoon level, minimum pressure is 944hPa. Even 2013 9th Typhoon 'Chebi', its peak air pressure is also low to 980hPa. In comparison, 2024 'Chebi' is only for Severe Tropical Storm level, peak air pressure exceeds the historical number of 10hPa, belonging to the weaker member of the same name Typhoon Intensity, mainly limited to at its higher latitude to reach peak, not getting sufficient ocean energy support to develop the higher-level Cyclone .
