Typhoon Thad, international code 198415, international name THAD, 1984 Northwest Pacific typhoon. Formed: 1984-10-18 06:00:00, ended: 1984-10-24 00:00:00. Peak intensity: Super Typhoon, minimum central pressure: 935 hPa, max wind: 61m/s.
Typhoon Thad at 1984-10-18 06:00:00 at 8.7°N, 150.1°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Super Typhoon intensity with max winds of 61 m/s (~220 km/h) and a minimum central pressure of 935hPa, recorded at 1984-10-21 18:00:00.
1984-10-24 00:00:00 After, Typhoon Thad gradually weakened and was numbered off on 1984-10-24 00:00:00 was numbered off; its lifecycle recorded 24 track points.
Typhoon Thad (198415) 的生命史始 at Northwest Pacific远洋海域, 整体路径呈现典型的“NW-NE”抛物线型Moving特征. formed初期 (10月18日至19日) , 系统位 at 低The latitude洋面 (8.7°N, 150.1°E附近) , 受副热带高压S侧引导气流影响, 稳定 toward NW. 随着纬度逐渐升高, 至10月21日06:00左右, Typhoon 中心抵达22.7°N, 143.7°E附近, 此时Moving direction发生显著转折.
From coordinate sequence analysis, between 18:00 and 06:00 on 21 October, the length from 144.1°E rapidly moved to 146.9°E, marking the Typhoon completed the turn toward, Go to W wind belt control area. Subsequently, the system accelerated toward NE, until 24 October dispersed at 35.5°N, 165.6°E in the ocean.
Thad的Intensity演变经历了快速增强, 巅峰维持及缓慢减弱三个阶段. 从10月18日的Nameless (10m/s) 起步, 系统在48h内迅速加强, at 10月20日06:00达到Typhoon 级别 (33m/s) . 随后爆发式增强, 仅用30h便跃升为Super Typhoon, max wind 达61m/s, 并 at 10月21日18:00至22日06:00期间维持这一peak intensity长达12h. 值得注意的是, 即使在转 toward 后的高The latitude海域 (30°N以N) , 其Intensity衰减相对缓慢, 直至10月23日06:00仍保持Severe Typhoon级别 (46m/s) , 显示出深厚的暖心结构韧性.
Compared with the same name History, 1984 Thad's Intensity was significantly higher at the following year's system of the same name. Data showed that 1988 Thad (198803) peaked only at Typhoon level, 1981 Thad (198112) peaked at Severe Typhoon level.
