Typhoon Muifa trajectory analysis
Track and Movement Characteristics
2011年第9号Typhoon “Muifa”的生命史长达13天, 整体路径呈现典型的NW行后转 toward NE的抛物线形态. formed初期 (7月27日) , 系统位 at Philippines以E洋面 (10°N, 141.6°E) , 随后稳定 toward NW. 在7月29日至8月1日期间, Typhoon 中心纬度从14°N迅速N抬至18.9°N, 经度维持在133°E-134°E附近, 显示其受副热带高压引导气流影响显著, Moving路径较为平直.
After August 3, the track took a marked turn. Once it moved north of 24°N, the typhoon's direction gradually shifted from northwest to north and then toward the northeast. From August 6 to 9, the system entered the mid- to high-latitude seas, turning eastward from 125.75°E to 126.3°E while its latitude rose sharply from 26.1°N to 43.9°N. The increasingly curved track showed that the westerlies' trough and ridge systems had begun to dominate its movement. It eventually weakened and dissipated over the northern Sea of Japan. It made no landfall and remained mainly over the open ocean.
Intensity evolution and historical comparison
“Muifa”经历了完整的生命周期, intensity 变化剧烈. 从初始的Tropical Depression (15m/s) 快速增强, at 8月1日达到巅峰状态, 成为Super Typhoon, 中心最低气压降至915hPa, max wind 高达65m/s. 此后, 随着纬度升高及环境场改变, intensity 呈波动下降Trend. 8月3日仍维持Severe Typhoon级别 (48m/s) , 但Go to 8月后半月, wind speed逐步降至35m/s左右并维持较长Time, 直至8月8日 weakened into Tropical Storm, 最终在8月9日以Tropical Depression (13m/s) 结束生命史.
MUFIFA in 2011 was significantly stronger than previous typhoons with the same name. Its peak pressure of 915hPa was much lower than that of MUFIFA in 2022 (940hPa), 2004 (960hPa), and 2017 (998hPa). The 2017 typhoon reached only tropical storm intensity, while the 2011 system attained super typhoon status and maintained high intensity for longer, indicating an exceptionally strong buildup and release of energy. It was the most intense cyclone with this name in nearly two decades.
