Typhoon Koinu at 2023-09-30 02:00:00 at 15.7°, lng 132.2° over the Northwest Pacific; initial intensity: Tropical Storm.
It peaked at Super Typhoon intensity with max winds of 55 m/s (~198 km/h) and a minimum central pressure of 930hPa, recorded at 2023-10-04 22:00:00.
2023-10-09 17:00:00 After, Typhoon Koinu gradually weakened and was numbered off on 2023-10-09 17:00:00 was numbered off; its lifecycle recorded 178 track points.
Typhoon “Koinu” (202314) 的生命史始 at 2023年9月30日凌晨, formed at Northwest Pacific洋面 (15.7°N, 132.2°E) . 在初始阶段, 系统呈现稳定的NW toward MovingTrend. 从9月30日至10月4日, Typhoon 中心The latitude由15.7°NN抬至22.1°N, During由132.2°EW进至122.5°E, 整体路径较为平直. 值得注意的是, 10月4日至10月5日期间, Typhoon 在接近巴士海峡附近海域时, Moving速度显著放缓, 纬度在21.9°N至22.1°N之间小幅震荡, 经度继续W移, 显示出受副热带高压引导气流减弱或地形相互作用影响的特征. 10月5日之后, 路径转 toward W direction, 横穿巴士海峡Go to S海NE部, 随后持续 toward WN, 最终 at 10月9日傍晚在S海N部减弱消散. 全生命周期内未记录到Landfall行为, 主要活动区域集中在开阔洋面及海峡水域.
“Koinu”的Intensity演变经历了快速增强, 维持巅峰, 波动减弱三个阶段. formed初期为Tropical Storm (18m/s) , 随后迅速加强, 仅用约两天Time便发展为Super Typhoon. 10月3日12时, 其Pressure降至935hPa°E, max wind 达52m/s; 10月5日06时再次达到Super Typhoon级别 (52m/s, 935hPa) . 数据显示, 其历史peak intensity出现在数据记录之外或采样间隙, minimum pressure 曾达930hPa°E, max wind 55m/s, 属 at 极强的热带气旋系统. 在Go to S海后, intensity 出现波动, 10月7日曾短暂重新加强至Severe Typhoon级别 (48m/s) , 但随后受环境因素影响, 结构逐渐破坏, wind speed由48m/s逐步衰减至15m/s, 气压回升至1002hPa, 最终转化为Nameless. 相较 at 历史同名Typhoon , 2023年“Koinu”凭借930hPa的极低Pressure和55m/s的峰值wind speed, 展现出显著的Severe Typhoon特征, 其Intensity维持在Super Typhoon级别的Time较长, 能量释放充分.
