The SummaryTyphoon Ma-on (international code 200423) is a 2004 Northwest Pacific typhoon; peak intensity Severe Typhoon, max wind 50m/s, minimum central pressure 945hPa, not in China Landfall, 2004-10-10 was numbered off, recorded 26 track points.
Typhoon Ma-on, international code 200423, international name MA-ON, 2004 Northwest Pacific typhoon. Formed: 2004-10-04 14:00:00, ended: 2004-10-10 02:00:00. Peak intensity: Severe Typhoon, minimum central pressure: 945 hPa, max wind: 50m/s.
Typhoon Ma-on at 2004-10-04 14:00:00 at 16.5°N, 134.5°E over the Northwest Pacific; initial intensity: Tropical Storm.
It peaked at Severe Typhoon intensity with max winds of 50 m/s (~180 km/h) and a minimum central pressure of 945hPa, recorded at 2004-10-08 02:00:00.
2004-10 02:00:00 After, Typhoon Ma-on gradually weakened and was numbered off on 2004-10 02:00:00 was numbered off; its lifecycle recorded 26 track points.
2004年第23号Typhoon “Ma-on” formed at Northwest Pacific洋面, 整体路径呈现典型的“NW行—转 toward NE”的抛物线形态. 初始阶段 (10月4日至6日) , 系统在134.5°E附近滞留并缓慢 toward NW, The latitude从16.5°N提升至20.6°N, During略微W移, 显示其处 at 副热带高压S侧引导气流中, Moving速度较缓. 10月7日至8日为关键转折期, Typhoon 中心在到达22.8°N, 130.6°E附近后, Moving direction由NW逐渐转为NE, 随后加速 toward NE direction行进. 这一转 toward 过程伴随着显著的纬度跃升, 从10月8日20时的26.7°N迅速移至10月9日08时的31.6°N, 表明其受到W风带槽前SW气流的强力牵引. 最终, 系统深入中高纬度海域, at 10月10日消散 at 39.1°N, 145.5°E附近. 全生命周期内无Landfall记录, 主要活动区域为开阔洋面.
“Ma-on” has experienced a complete life history of intensity changes, showing the characteristics of “slow enhancement – rapid eruption – maintenance peak – rapid weakening”. initially as Tropical Storm, intensity stable at 20m/s to 23m/s. From October 7 Go to rapid enhancement period, wind speed increases from 35m/s to 50m/s within 24h, air pressure synchronized to 945hPa, reach Severe Typhoon level. peak intensityined Time longer, from October 8.05 to 20, three consecutive observation pointsined 50m/sMax Wind and 945hPa minimum air pressure, stable structure.
Its peak atmospheric pressure (945hPa) was significantly lower at 2022 “Ma-on” (970hPa) and 2016 “Ma-on” (996hPa) , showing a stronger explosive force; but slightly higher at 2011 “Ma-on” (930hPa, Super Typhoon).This suggests that although the 2004 version did not meet the Super Typhoon standard, it remains at stronger individuals in the Northwest Pacific Autumn Typhoon, its Intensity evolution is consistent with the typical climate characteristics of autumn Typhoon in warm waters rapidly strengthened, turning toward after rapid disappearance.
