Typhoon Sepat Route Characteristics
Path and Moving Characteristics
The life cycle of Typhoon Sepat (200709) began over the Northwest Pacific at 02:00 on August 13, 2007, at an initial position of 16.9°N, 135.3°E. During its early formation, the system generally moved toward the WNW. From August 13 to 16, its latitude changed little, remaining between 16°N and 17°N, while its longitude shifted rapidly westward from 135.3°E to 127.2°E, indicating a steady westward component. Between 02:00 and 20:00 on August 16, the track turned markedly northward, with its latitude rising rapidly from 16.7°N to 18.7°N, marking a shift from a purely westward course toward the NW. It then continued moving toward the NW until gradually turning toward the north in the latter part of August 19. At approximately 02:00 on August 20, it weakened and dissipated near 27°N, 116.9°E. The typhoon made no recorded landfall and remained at sea throughout its life cycle.
Intensity Evolution Analysis
Sepat经历了典型的“快速增强-巅峰维持-逐渐减弱”过程. formed初期为Tropical Storm (18m/s, 998hPa) , 随后迅速加强, 仅用约36h便发展为Typhoon 级别. 8月16日02:00, 其Intensity已达Super Typhoon标准 (55m/s, 930hPa) . 巅峰时刻出现在8月16日20:00, 中心最低气压降至910hPa, max wind 高达65m/s. 值得注意的是, 在8月16日20:00至8月18日00:00的近40h内, Sepat长Time维持Super TyphoonIntensity, 气压稳定在910-925hPa区间, wind speed保持在55-65m/s的高位, 显示出极强的结构稳定性. 自8月18日06:00起, 随着 toward NMoving, 系统开始显著减弱, 由Severe Typhoon逐级降为Typhoon , Severe Tropical Storm, 最终在生命末期 weakened into Tropical Depression (15m/s, 997hPa) .
Same-Name Comparison
2007 Sepat peak intensity is Super Typhoon, minimum pressure 910hPa, max wind 65m/s. In comparison, 2025 , 2019 , 2013 and 2001 Sepat Typhoon peak intensity is only Tropical Storm level, minimum pressure between 990hPa to 998hPa respectively, max wind does not exceed Tropical Storm ceiling.
