Typhoon Bolaven trajectory analysis
Track Movement and Recurvature Characteristics
2023年第15号Typhoon “Bolaven”的生命史始 at Northwest Pacific远洋海域, 整体路径呈现显著的“先W后N再NE”的抛物线型轨迹. formed初期 (10月7日至9日) , 系统位 at 低纬度海域 (约10°N附近) , 受引导气流影响, 主要 toward W direction缓慢Moving, 经度从153.9°EW移至149°E. 10月9日14时至10月11日02时期间, typhoon track发生关键转折, Moving direction逐渐由W转为NW, 纬度迅速从11.6°N提升至16.1°N.
After reaching maturity, the typhoon’s center crossed 18°N at 14:00 on October 11 and turned further toward the NNE. Especially after 14:00 on October 12, as it moved beyond 21.8°N, the system accelerated toward the NE and resumed its eastward expansion, rapidly advancing from 143.5°E to 155.8°E. Throughout this period, the typhoon made no landfall, remained over open waters, and ultimately weakened to typhoon intensity near 33.5°N, 155.8°E at 05:00 on October 14, when observations ended.
Intensity evolution and historical comparison
“Bolaven”经历了极为剧烈的爆发式增强过程. 从10月7日的Tropical Storm (18m/s, 998hPa) 起步, 仅用不到4天Time, Pressure骤降98hPa至900hPa, max wind 激增50m/s达到68m/s, at 10月11日14时晋升为Super Typhoon. 值得注意的是, 该Intensity峰值维持了约36h (10月11日14时至10月12日14时) , 期间气压稳定在900hPa, wind speed保持68m/s, 显示出极强的结构稳定性. 10月13日02时后, 随着纬度升高至24°N以N, 系统开始减弱, 气压回升至970hPa, wind speed降至35m/s.
Its lowest air pressure (900hPa) is much lower at 935hPa of the 2012 type Typhoon, even stronger at 2018 (1000hPa), 2005 (975hPa) and 2000 records. 2018 'Bolaven' is only Tropical StormIntensity, and the 2023 version not only reached the Super Typhoon level, but the core indicators are record highs in the sequence of the name, reflecting its rare extreme Intensity characteristics in the same list.
