Typhoon Thad Route Analysis
Track and Movement Characteristics
Typhoon Thad (198415) 的生命周期始 at Northwest Pacific低纬度海域, 整体路径呈现显著的“先NW, 后NE”的抛物线型转 toward 特征. formed初期 (10月17日至19日) , 系统在8.7°N至12.9°N之间缓慢 toward NW, 经度在145.9°E至148.6°E之间小幅摆动, 显示其受副热带高压S侧引导气流影响较大, Moving速度相对迟缓. 10月20日起, 随着纬度N抬至15°N以上, 系统开始加速 toward NNW direction推进.
The key turning point occurred around October 22. At 02:00 on October 22, the system was at 24.8°N, 144.2°E, then moved to 27.2°N, 146.7°E after 12h, showing a clear eastward shift in longitude and marking a turn from a NW toward to a NE toward. The typhoon then rapidly moved toward higher latitudes, eventually weakening into a severe tropical storm near 36.6°N, 167°E by 08:00 on October 24, when observations ended. Throughout its lifecycle, the typhoon made no landfall and remained over the open ocean.
Intensity evolution and historical comparison
Thad的Intensity演变经历了典型的“快速增强-巅峰维持-迅速减弱”过程. 从10月17日的Tropical Depression (12m/s, 1000hPa) 起步, 系统在N上过程中持续整合能量. 特别是在10月20日至22日期间, intensity 爆发式增长: wind speed从20m/s飙升至55m/s, Pressure从985hPa骤降至925hPa, at 10月22日14:00达到Super Typhoon级别, 这也是其生命史中的巅峰状态.
However, it maintained its peak intensity for only a very short time. After moving into the cold waters of the higher latitudes, its structure rapidly deteriorated. At 02:00 on October 23, only 12h after its peak, wind speed had fallen to 35m/s and central pressure had risen to 965hPa, downgrading it to a typhoon. By 08:00 on October 24, wind speed had further decreased to 25m/s.
Compared with previous storms of the same name, Thad in 1984 was significantly stronger. Its peak central pressure was 956hPa in 1981 and 965hPa in 1988, while the 1984 storm reached a minimum central pressure of 925hPa and maximum winds of 55m/s. These peak typhoon intensities far exceeded those of the other two storms, indicating that the Northwest Pacific had highly favorable conditions for typhoon development that autumn.
