Typhoon Ma-on Route Characteristics
Track and Movement Characteristics
2004年第23号Typhoon “Ma-on”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3日至5日) , 系统位 at 16.5°N附近, 受副热带高压S侧引导气流影响, 主要 toward W direction缓慢Moving, 经度从135.3°EW移至134.4°E. 随后, 路径逐渐转为NW direction, 纬度稳步提升至20°N以N.
The key turning point occurred around October 8. Between 14:00 on October 7 and 14:00 on October 8, the typhoon center remained between 22.2°N and 25.1°N and 130.7°E and 132.2°E. This was the northernmost point in its lifetime, accompanied by a brief period of little movement before it accelerated markedly toward the northeast. From October 9 to 10, its speed increased sharply, with its latitude rising rapidly from 28.9°N to 39.6°N and its longitude advancing eastward to 150.1°E. This showed that it had fully escaped the subtropical high and merged into the westerly flow, eventually becoming an extratropical cyclone over the eastern waters of Japan and dissipating. It made no landfall and was a typical remote-ocean typhoon that recurved toward the northeast.
Intensity evolution and historical comparison
Ma-on completed a full cycle of intensification and weakening. It initially developed into a tropical depression, strengthened into a tropical storm on October 4, and rapidly intensified as it moved northwestward into warmer waters from October 6 to 7, progressing from a severe tropical storm to a typhoon. It reached severe typhoon status at 14:00 on October 7. Its peak intensity occurred at 14:00 on October 8, when the minimum central pressure fell to 940 hPa and maximum winds reached 50 m/s. It then weakened while moving north into colder waters, downgrading to a typhoon at 14:00 on October 9 and further weakening into a severe tropical storm and then a tropical storm in the early hours of October 10.
Compared with other storms of the same name, the 2004 Ma-on had above-average intensity. Its peak pressure of 940 hPa was higher than that of the sixth typhoon Ma-on in 2011 (935 hPa, super typhoon), but considerably lower than those of the ninth typhoon Ma-on in 2022 (970 hPa, typhoon) and the 24th typhoon Ma-on in 2016 (998 hPa, tropical storm). The data show substantial intensity differences among storms sharing the same name. The 2004 storm displayed strong rapid intensification, although its extreme intensity was slightly surpassed by the 2011 storm.
