Typhoon Nanmadol trajectory characteristics
Path and Moving Characteristics
2011年第11号Typhoon “Nanmadol”的生命史长达10天, 整体路径呈现典型的NW toward Moving后逐渐转 toward N上的Trend. formed初期 (8月21日) , 系统位 at Philippines以E洋面 (11.9°N, 128.8°E) , 随后稳定 toward NW direction推进. 在8月25日至26日期间, Typhoon 中心纬度从16.3°N快速N抬至17.4°N, 经度由125.2°EW移至123.45°E, 显示其在接近TaiwanE部海域时保持了较强的NW行进分量.
Notably, the typhoon slowed significantly after August 28 and made a distinct northward turn. From 10:00 on August 28 to 01:00 on August 31, its latitude increased steadily from 20.57°N to 24.6°N, while its longitude changed very little, shifting only from 121.37°E to 119.07°E. This indicates that the system nearly stalled while moving slowly northward near the Taiwan Strait, before weakening into a tropical depression on August 31 and leaving the monitored area. No landfall was recorded during its entire life cycle, with most activity concentrated over open waters and nearshore seas.
Intensity evolution and historical comparison
“Nanmadol”经历了完整的生命循环, intensity 变化剧烈. 从初始的Tropical Depression (10m/s) 迅速增强, at 8月26日17:00达到巅峰状态, 此时中心最低气压降至925hPa, max wind 达60m/s, 评定为Super Typhoon. 然而, 巅峰状态维持Time较短, 随后Intensity迅速衰减. 8月27日晚至29日凌晨, Pressure回升至965hPa以上, wind speed降至40m/s以下, 等级由Typhoon 降为Severe Tropical Storm, 直至最终 weakened into Tropical Depression.
Compared with previous storms of the same name, the 2011 Nanmadol had above-average intensity. Its peak pressure of 925hPa was higher than those of the 2004 Nanmadol (950hPa) and 2017 Nanmadol (985hPa), but slightly weaker than the 2022 Nanmadol (915hPa). The 2017 storm only reached severe tropical storm intensity, the weakest of the group, while the 2022 storm set a new intensity record for the name. Although the 2011 Nanmadol did not make landfall, its brief super typhoon phase and rapid weakening afterward demonstrated the typical intensity fluctuations of Northwest Pacific typhoons under specific environmental conditions.
