Typhoon Bolaven trajectory analysis
Track and Movement Characteristics
2005年第23号Typhoon “Bolaven”的生命史始 at Northwest Pacific洋面, 整体路径呈现先W行, 后NW转 toward , 最终N上的复杂形态. formed初期 (11月15日至17日) , 系统中心位 at 12.3°N-13.5°N, 128.8°E-130.5°E之间, 主要受引导气流影响 toward WSW direction缓慢Moving, 期间经度变化较小, 纬度略有波动. 11月18日凌晨至19日上午, Typhoon Go to 快速W移阶段, 中心从128°E迅速跨越至124.8°E, 同时纬度由13.6°NN抬至15.2°N, 显示出明显的NW toward Moving分量.
值得注意的是, 11月19日11:00至17:00期间, Typhoon 在124.8°E附近出现路径转折迹象, Moving direction逐渐由NW转为N. 随后系统沿123°E-124.3°E经线附近 toward N推进, 直至11月20日20:00消散 at 18.2°N, 123°E附近. 全生命周期内, 该Typhoon 未Landfall任何land, 始终在海上活动, track pointstotal 计26个, 轨迹相对平滑但转 toward 明确.
Intensity evolution and historical comparison
在Intensity变化方面, “Bolaven”经历了典型的“增强-维持-减弱”过程. 初始为Tropical Depression (14m/s, 999hPa) , 随后迅速加强, at 11月17日02:00达到Severe Tropical Storm级别. 11月18日02:00, Pressure降至最低值975hPa, max wind 达33m/s, 正式升级为Typhoon 级别. 此后约30h内 (11月18日02:00至11月19日11:00) , Typhoon 维持在peak intensity, 气压稳定在975hPa, wind speed保持33m/s, 显示出较强的结构稳定性. 11月19日17:00起, 系统开始减弱, 降级为Severe Tropical Storm, 并最终在11月20日傍晚 weakened into Tropical Depression.
Its peak air pressure was 975hPa much higher at the Super Typhoon level in 2023 (900hPa) and 2012 (935hPa), but slightly lower at the 2018 Tropical Storm level (1000hPa) . Compared to the 2000 Severe Tropical Storm, the 2005 version reached the Typhoon level standard, indicating that it gained more developmental energy in the ocean environment at the end of autumn, but did not reach extreme Intensity.
