Typhoon Seth Route Analysis
Path and Moving Characteristics
Typhoon Seth (199124) began over the open waters of the Northwest Pacific and followed a typical westward track, with no significant turns or landfall. From its formation position (7°N, 164°E) to its dissipation position (18.5°N, 119.4°E), it was mainly steered by the easterly flow on the southern side of the subtropical high, moving steadily westward. Its latitude gradually increased from an initial 7°N to a maximum of about 19.7°N, then fluctuated between 17°N and 19°N.
路径轨迹显示, Typhoon 在11月5日至6日期间到达最N端 (约19.7°N) , 此时经度约为139.5°E至140.9°E区间. 此后, 系统虽继续W行, 但纬度出现小幅S落再N抬的震荡, 最终在Taiwan以E海域减弱消散. 全生命周期长达14天以上, track points多达59个, 表明其Moving速度相对平稳, 且在广阔洋面上拥有较长的Active期. 由 at 全程无Landfall记录, 该Typhoon 主要对海上航线及远洋作业构成潜在影响, 未直接造成land灾害.
Intensity evolution and historical comparison
Seth’s intensity followed a complete formation, intensification, peak, maintenance, and weakening cycle. Initially a tropical depression, it rapidly intensified into a tropical storm within 48h and became a typhoon on November 3. It then entered a rapid intensification phase, rising from typhoon strength (35m/s) to severe typhoon strength (50m/s) in just two days, with its minimum central pressure falling to 930hPa. Notably, it maintained peak intensity (50m/s, 930hPa) for at least 24h from November 5 to 6, indicating a stable core structure.
11月7日起, intensity 开始波动下滑, 短暂减弱后 at 11月9日至11日再次回升至Severe Typhoon级别 (45m/s, 940hPa) , 形成“二次峰值”特征, 这在深秋Typhoon 中较为少见. 最终在Go to S海N部前夕, 受环境因素影响迅速减弱, at 11月14日消散.
与同名Typhoon 对比, 1994年的Seth (199430) peaked at Super Typhoon级别, minimum pressure 为925hPa, 略低 at 1991年Seth的930hPa. 尽管1991年Seth未达到Super Typhoon标准, 但其长达两周的生命史和稳定的Severe Typhoon级维持Time, 体现了其深厚的热力结构和良好的海洋环境支持.
