Typhoon Dujuan trajectory
Track and Movement Characteristics
Dujuan, the 21st typhoon of 2015, formed over the Northwest Pacific and followed a generally steady northwestward track. From its initial position at 15.3°N, 141.7°E at 20:00 on September 21 until its landfall in Taiwan on September 28, its center continued moving northwest, with latitude rising steadily from 15.3°N to 24°N and longitude shifting from 141.7°E to 122.9°E. Its track remained only slightly curved during this period, with no obvious northward turn or stagnation, indicating strong steering-flow influence.
该Typhoon 具有典型的双次Landfall特征. 首先 at 9月28日17:50在Taiwan宜兰Landfall, 随后穿越Taiwan岛Go to Taiwan海峡, intensity 迅速衰减. 紧接着 at 9月29日08:50在Fujian莆田 City秀屿区coastal 进行第二次Landfall. LandfallFujian后, Typhoon 继续 toward NNW direction深入内陆, 最终 at 9月30日下午在江W附近减弱消散. 整个生命史历时约9天, track points分布密集且连贯, 完整记录了从远洋 formed到内陆消亡的全过程.
Intensity evolution and historical comparison
“Dujuan”的Intensity演变经历了显著的快速增强阶段. 从9月23日发展为Tropical Storm (18m/s) 开始, 其Pressure在4天内从998hPa急剧下降至930hPa, max wind 从18m/s飙升至58m/s, at 9月27日20时达到巅峰状态, 认定为Super Typhoon. 值得注意的是, 在接近Taiwan前夕 (9月28日14时) , 其仍维持55m/s的Super TyphoonIntensity, 显示其在Landfall前保持了极高的能量水平. 然而, 受地形摩擦及内陆环境影响, 第一次Landfall后Intensity骤降, 至9月29日08时已 weakened into Severe Tropical Storm (30m/s) , 二次Landfall后进一步瓦解为Tropical Depression.
Compared with previous typhoons bearing the same name, Dujuan in 2015 was significantly stronger. Its minimum central pressure of 930 hPa was far lower than the 950 hPa recorded by Dujuan in 2003, 985 hPa in 2009, 990 hPa in 2021, and 970 hPa in 2026. Its peak maximum wind of 58 m/s also surpassed the peak intensity of earlier storms with the same name, most of which reached only typhoon or severe tropical storm strength. Data show that the 2015 Dujuan was the strongest same-named typhoon in the observational record, particularly notable for its explosive intensification and sustained high intensity.
