The SummaryTyphoon Agness (international code 200430) is a 2004 Northwest Pacific typhoon; peak intensity Tropical Storm, max wind 23m/s, minimum central pressure 990hPa, not in China Landfall, 2004-12-21 was numbered off, recorded 3 track points.
Typhoon Agness, international code 200430, international name NORU, 2004 Northwest Pacific typhoon. Formed: 2004-12-20 02:00:00, ended: 2004-12-21 20:00:00. Peak intensity: Tropical Storm, minimum central pressure: 990 hPa, max wind: 23m/s.
Typhoon Agness at 2004-12-20 02:00:00 at 16.2°N, 146.4°E over the Northwest Pacific; initial intensity: Tropical Storm.
It peaked at Tropical Storm intensity with max winds of 23 m/s (~83 km/h) and a minimum central pressure of 990hPa, recorded at 2004-12-20 08:00:00.
2004-12-21 20:00:00 After, Typhoon Agness gradually weakened and was numbered off on 2004-12-21 20:00:00 was numbered off; its lifecycle recorded 3 track points.
Typhoon Agness (No.200430) 的生命史较短, 主要活动区域位 at Northwest Pacific远洋海域. 根据观测数据, 该Typhoon formed at 2004年12月20日02时, 初始Position为lat 16.2度, lng 146.4度. 在随后的6h内, 系统 toward NW direction轻微Moving至lat 17.4度, lng 146.2度, 此时During略微W移, 显示出受低层引导气流影响的初期特征. 然而, 从12月20日08时至12月21日20时的长时段观测来看, typhoon track发生了显著的转 toward . 系统迅速转为NE, 最终到达lat 26度, lng 154.8度附近. 这一路径变化表明, Agness在 formed后不久便受到中The latitudeW风带或副热带高压边缘气流的牵引, 加速 toward 高纬度海区Moving. 整个过程中, Typhoon 未触及任何陆地, 无Landfall记录, 始终在开阔洋面上运行.
在Intensity方面, Agness维持Tropical Storm等级, 生命史内Intensity波动较小. formed初期Max Wind为20m/s, 中心最低气压992hPa; 在12月20日08时达到巅峰状态, max wind 增至23m/s, Pressure降至最低值990hPa. 此后随着The latitude升高及可能的垂直风切变影响, 至12月21日20时消散前, intensity 略有减弱, wind speed回落至20m/s, 气压回升至992hPa. 整体而言, 该系统属 at 弱Tropical Storm级别, 结构松散且持续Time短.
Compared with the historical typhoon, the 2004 Agness Intensity is significantly weaker.Return to the previous data, the 1989 33th Typhoon Agness has developed into a Super Typhoon, very destructive; the 1983 19th Typhoon Agness has also reached the typhoon level; even the weaker 1986 23th and 1983 11th Agness, its peak intensity has also reached the Severe Tropical Storm level.
| Time | The latitude | During | Intensity | Wind (m/s) | Pressure (hPa) | Moving toward |
|---|---|---|---|---|---|---|
| 2004-12-20 02:00:00 | 16.2°N | 146.4°E | Tropical Storm | 20 | 992 | |
| 2004-12-20 08:00:00 | 17.4°N | 146.2°E | Tropical Storm | 23 | 990 | |
| 2004-12-21 20:00:00 | 26°N | 154.8°E | Tropical Storm | 20 | 992 |
