Typhoon Ma-on, international code 200423, international name MA-ON, 2004年Northwest PacificTyphoon . formedTime: 2004-10-04 14:00:00, 结束Time: 2004-10-10 02:00:00. peak intensity: Severe Typhoon, 最低Pressure: 945 hPa, max wind : 50m/s.
Typhoon Ma-on at 2004-10-04 14:00:00 at 16.5°, lng 134.5° 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”经历了完整的生命史Intensity变化, 呈现出“缓慢增强—快速爆发—维持巅峰—迅速减弱”的特征. 初期作为Tropical Storm, intensity 稳定在20m/s至23m/s. 10月7日起Go to 快速增强期, wind speed在24h内从35m/s激增至50m/s, 气压同步下降至945hPa, 达到Severe Typhoon级别. peak intensity维持Time较长, 从10月8日05时至20时, 连续三个观测点保持50m/sMax Wind和945hPa最低气压, 结构稳固. 转 toward NE后, 受高The latitude冷海水及垂直风切变影响, intensity 迅速衰减, 10月9日20时已 weakened into Severe Tropical Storm.
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.
