Typhoon Dianmu, international code 200406, international name DIANMU, 2004年Northwest PacificTyphoon . formedTime: 2004-06-13 20:00:00, 结束Time: 2004-06-21 20:00:00. peak intensity: Super Typhoon, 最低Pressure: 910 hPa, max wind : 65m/s.
Typhoon Dianmu at 2004-06-13 20:00:00 at 9.5°, lng 136° over the Northwest Pacific; initial intensity: Tropical Storm.
It peaked at Super Typhoon intensity with max winds of 65 m/s (~234 km/h) and a minimum central pressure of 910hPa, recorded at 2004-06-17 08:00:00.
2004-06-21 20:00:00 After, Typhoon Dianmu gradually weakened and was numbered off on 2004-06-21 20:00:00 was numbered off; its lifecycle recorded 39 track points.
Typhoon “Dianmu” (200406) 的生命史始 at 2004年6月13日20时, formed at Northwest Pacific低The latitude海域 (9.5°N, 136°E) . 在初始阶段, 系统呈现缓慢的NW toward MovingTrend. 随着Intensity的迅速增强, 其Moving路径发生显著偏转. 从6月16日02时至6月17日14时, Typhoon 中心坐标由 (13.5°N, 136.8°E) 移至 (17.4°N, 133.6°E) , During持续W移而纬度N抬, 显示出稳定的NW特征.
值得注意的是, 该Typhoon 在达到peak intensity后, 路径出现明显的转 toward 迹象. 6月18日之后, Moving direction逐渐转为N, 随后在6月20日20时左右, 坐标变为 (29.4°N, 131.2°E) , 相较 at 前一时次 (25.6°N, 129.3°E) , During开始 toward E回流, 表明系统在中高The latitude受W风带引导气流影响, 完成了从NW行到NE行的转 toward . 最终, Typhoon at 6月21日20时在 (37.9°N, 137.3°E) weakened into Tropical Storm并结束观测. 整个生命周期内, 该系统未Landfall任何陆地, 全程在洋面上活动.
“Dianmu” showed extremely rapid explosive enhancement process. From the 13th of June’s Tropical Storm (18m/s, 998hPa) start, only in about 52h intensified into Super Typhoon. especially during the 16th to 17th of June, Pressure dropped sharply from 935hPa to the minimum of 910hPa°E, max wind climbed to 65m/s, to the Super Typhoon level.
然而, 巅峰状态维持Time较短. 自6月17日14时达到极值后, 系统开始减弱, 至6月18日08时, wind speed降至55m/s, 气压回升至930hPa. Go to 中高The latitude后, 受海温降低及垂直风切变增大等因素影响, intensity 持续衰减, 最终转化为温带气旋前消散.
Its lowest air pressure (910hPa) is much lower at 2021 (998hPa), 2016 (978hPa) and 2010 (980hPa) of the same name Typhoon .
