Typhoon Orchid Trail Characteristics
Track and Turning Characteristics
Typhoon Orchid (199121) 的生命史始 at Northwest Pacific远洋海域, 整体路径呈现典型的“W进-N折-NE转 toward ”抛物线形态. formed初期 (10月3日至6日) , 系统稳定 toward WMoving, 纬度维持在18.5°N至19.3°N之间, 经度从142.5°E快速W移至133.8°E, 显示出受副热带高压S侧引导气流控制的特征. 10月7日至8日, Typhoon 在130°E附近达到最W端, 随后路径发生显著转折. 10月9日起, 系统开始 toward NE direction加速Moving, 经度由131.7°E迅速E扩至159°E, 纬度则从24°N一路飙升至48°N. 这一阶段路径曲率较大, 表明其受到W风带槽前气流牵引, 完成了从低纬 toward 高纬的长About 离输送. 全生命周期内无Landfall记录, 始终在海上活动, 最终 at Japan以E海域转化为温带气旋或消散.
Intensity evolution and historical comparison
该Typhoon 经历了完整的生命周期Intensity变化. 初始阶段为Tropical Depression, 随后稳步增强, at 10月7日02:00发展为Severe Typhoon (45m/s, 950hPa) . 巅峰状态出现在10月7日20:00至10月8日14:00期间, 中心最低气压降至930hPa, max wind 达50m/s, 并维持了约18h的高Intensity平台期. 10月9日后, 随着纬度升高和海温降低, intensity 逐渐减弱, 10月10日降级为Typhoon , 10月11日进一步 weakened into Severe Tropical Storm. 尽管wind speed下降, 但在N上过程中气压回升相对缓慢, 直至10月14日Go to 高纬度寒冷海域后, 仍保持Tropical Storm级别Intensity.
与历届同名Typhoon 相比, 1991年Orchid的peak intensity (930hPa) 与1994年及1983年的同名Typhoon 持平, 均达到极强水平; 优 at 1987年 (955hPa) 和1980年 (960hPa) 的同类系统. 这表明“Orchid”这一命名序列在历史上倾 toward at formed高Intensity的Typhoon 系统, 而1991年的这次过程在Intensity上属 at 该命名序列中的第一梯队, 具备典型的深秋Severe Typhoon特征.
