Typhoon Dujuan (201521) formed at Northwest Pacific洋面, 整体路径呈现稳定的WNTrend. 从9月23日02:00的初始Position (17.7°N, 138.2°E) 至9月28日Landfall前, 其The latitude由17.7°N逐步N抬至24.3°N, During则由138.2°E持续W进至122.5°E. 观测数据显示, 该Typhoon 在接近Taiwan岛过程中未出现明显的路径折 toward 或停滞, 保持较为线性的推进态势. 9月28日17:50在Taiwan宜兰首次Landfall后, 路径继续 toward W穿越Taiwan海峡, 并 at 次日08:50在Fujian莆田 City秀屿区coastal 二次Landfall. LandfallFujian后, Typhoon 中心迅速 toward 内陆深入并转 toward NW, 最终 at 9月29日17:00在江W附近 weakened into Nameless并结束生命史. 整个生命周期历时约6天半, track points密集, 显示其Moving过程连续且规律性强.
Dujuan的Intensity演变经历了典型的“快速增强—巅峰维持—Landfall减弱”过程. formed初期为Tropical Storm, 随后在 toward WMoving过程中迅速加强, at 9月26日发展为Typhoon , 并在27日15:00达到Super Typhoon级别. 其巅峰状态维持Time较长, 从9月27日15:00至9月28日09:00, 连续多个时次保持Max Wind58m/s, 最低气压925hPa的Super TyphoonIntensity. 在首次LandfallTaiwan前, intensity 略有波动但仍维持Super Typhoon等级; LandfallTaiwan后Intensity显著下降, 降至Severe Typhoon级别; 穿越海峡后再次LandfallFujian时已 weakened into Severe Tropical Storm, 随后在内陆快速衰减.
In comparison with the historical typhoon, Dujuan's intensity in 2015 far surpassed the intensity of the typhoon in 2021 (top Tropical Storm, 990hPa) and 2009 (top Severe Tropical Storm, 980hPa). however, its peak intensity is slightly lower at 2003 Dujuan (top Super Typhoon, 916hPa).
