Typhoon Koni Trail Characteristics
Track and Turning Characteristics
2015年第15号Typhoon “Koni”的生命史长达12天, 整体路径呈现显著的“W行—NW行—转 toward NE”的复杂形态. formed初期 (8月15日) , 系统位 at Philippines以E洋面 (12.9°N, 148.2°E) , 受副热带高压引导稳定 toward WMoving. 至8月17日, Center移至17°N, 140.5°E, 随后路径逐渐 toward NW direction调整. 值得注意的是, 该Typhoon 在接近Taiwan以E海域时出现明显的路径摆动: 8月20日至22日期间, 中心纬度在19°N至21.4°N之间小幅波动, 经度在122.3°E至124.3°E之间徘徊, 显示出受周围流场牵制而产生的停滞少动特征.
8月23日后, 随着纬度N抬至22.9°N以上, Typhoon 开始加速 toward NE, 完成关键的路径转 toward . 此后, “Koni”穿越E海及Japan海, 最终 at 8月25日凌晨LandfallJapan九州岛W部coastal , 并继续N上, at 8月27日凌晨在俄罗斯海参崴附近coastal 再次Landfall后消散. 整个路径跨度极大, 从低纬热带海域一直延伸至中高纬度的44.3°N, 体现了典型的长寿命Typhoon 远途输送特征.
Intensity evolution and historical comparison
Koni’s Intensity evolution experienced two significant enhancements.The first rapid enhancement occurred on August 15 to 17, in just two days by Tropical Storm (18m/s) jumped to Super Typhoon (52m/s) and Pressure dropped to 935hPa. Then during August 19 to 21, the intensity fluctuated slightly but remained above the Severe Typhoon level.The second peak appeared on August 24, the system again strengthened during the transition toward NE, reaching its lifetime highest intensity: Max Wind55m/s, minimum pressure 930hPa,ining the Superhoon Typhoon level until August 25 before Landfall rapidly weakened.
Its peak air pressure (930hPa) was far lower at 2009 'Koni' (985hPa, only to Tropical Storm) and 2003 'Koni' (976hPa, Typhoon). Although the 2020 'Koni''s minimum air pressure was lower (905hPa), the 2015 version showed extremely strong energy maintenance capabilities with 55m/s extremely high wind speed and up to 12 days of Active period.
