Typhoon Rammasun trajectory
Track and Movement Characteristics
Typhoon Rammasun (201409) began its life over the Northwest Pacific and initially followed a stable west-northwest track. From its formation point (8.8°N, 152.3°E) until its first landfall in central Philippines, it moved mainly along the southern edge of the subtropical high, with relatively little change in latitude and a broad longitudinal span, indicating strong steering-flow control. After crossing the Philippine islands and entering the South China Sea, its track turned sharply northward. The coordinates show that from July 16 to 18, its latitude rose rapidly from 15.43°N to 19.82°N, indicating a marked northward acceleration over the northern South China Sea toward Hainan and the Leizhou Peninsula coast. This westbound-then-northward track pattern enabled it to strike Wenchang in Hainan, Xuwen in Guangdong, and Fangchenggang in Guangxi with extreme intensity, producing the rare impact of multiple landfalls.
Intensity evolution and historical comparison
Typhoon Rammasun exhibited the typical intensity pattern of rapid intensification, sustained peak intensity, and weakening after landfall, with exceptional explosive power. It reached super typhoon intensity on July 15 (52m/s, 938hPa). Although terrain friction caused a brief weakening, it reorganized and intensified rapidly after entering the South China Sea. Particularly before landfall in Hainan on July 18, its pressure fell to 890hPa and its maximum wind speed surged to 71m/s, approaching its lifetime peak of 888hPa and 72m/s. Maintaining super typhoon intensity so close to landfall was extremely rare. It then gradually weakened to a severe typhoon and a severe tropical storm while crossing the Qiongzhou Strait and making landfalls in Xuwen and Fangchenggang.
Compared with storms of the same name in previous years, the 2014 Rammasun was significantly more destructive. The 2002 Rammasun peaked only as a severe typhoon (950hPa). Although the 2008 Rammasun reached super typhoon intensity, its minimum pressure was 935hPa. By comparison, the 2014 Rammasun had a minimum pressure more than 47hPa lower and maximum wind nearly 20m/s stronger, demonstrating the extreme intensity that made it one of the world's most severe typhoons that year.
