Typhoon Seth Route Analysis
Track and Movement Characteristics
Typhoon Seth (199430) 的生命史始 at Northwest Pacific远洋海域, 整体路径呈现典型的“NW行—转 toward NE”的抛物线形态. formed初期 (10月2日至5日) , 系统位 at 低纬度海域 (11°N-13°N) , 受副热带高压S侧引导气流影响, 稳定 toward W, 横穿马里亚纳群岛以E海域. 10月6日至8日期间, 随着纬度逐渐N抬至18°N附近, 路径 direction发生显著转折, 由W转为NNW direction加速推进.
The key turning point occurred between October 9 and 10. As the system moved north into the range of 23°N to 25°N, the southwesterly flow ahead of a westerly wind-band trough caused its track to turn sharply right toward the northeast. The typhoon then rapidly crossed the waters east of the Ryukyu Islands and moved deep into the mid- to high-latitude region. After October 12, its movement speed increased markedly, with its latitude rising rapidly from 39.3°N to 49°N. It ultimately became extratropical and dissipated over the cold waters east of the Kuril Islands. No landfall was recorded, and it remained mainly over the open ocean.
Intensity evolution and historical comparison
The typhoon went through the full stages of formation, rapid intensification, maintenance, and decay. Intensity rose slowly during its initial stage, taking about three days to strengthen from a tropical depression into a severe tropical storm. After entering rapid intensification, its explosive development was remarkable: following its upgrade to a typhoon on October 6, it reached peak intensity at 02:00 on October 8 in less than 48 hours. The minimum central pressure fell to 925 hPa and the maximum sustained wind speed reached 55 m/s, making it a super typhoon. It maintained peak intensity only briefly before its intensity began declining in stages as it moved toward higher latitudes, encountering stronger vertical wind shear and cooler sea surface temperatures. It weakened into a typhoon on October 10 and further downgraded to a severe tropical storm on the 11th, eventually returning to a tropical depression late in its life.
Compared with the typhoon of the same name, the 1991 Seth had a slightly higher peak intensity than the 1994 Seth (199124). Data show that the 1991 typhoon reached a minimum central pressure of 930 hPa and attained severe typhoon status, whereas Seth in 1994 reached a minimum central pressure of 925 hPa and the higher super typhoon intensity of 55 m/s. This indicates that the 1994 Seth accumulated more energy in its core. Although neither system directly caused landfall disasters, the 1994 case exhibited stronger extreme-intensity characteristics.
