Typhoon Thad, international code 198112, international name THAD, 1981 Northwest Pacific typhoon. Formed: 1981-08-16 12:00:00, ended: 1981-08-23 18:00:00. Peak intensity: Severe Typhoon, minimum central pressure: 955 hPa, max wind: 43m/s.
Typhoon Thad at 1981-08-16 12:00:00 at 19.6°N, 131.8°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Severe Typhoon intensity with max winds of 43 m/s (~155 km/h) and a minimum central pressure of 955hPa, recorded at 1981-08-19 06:00:00.
1981-08-23 18:00:00 After, Typhoon Thad gradually weakened and was numbered off on 1981-08-23 18:00:00 was numbered off; its lifecycle recorded 30 track points.
Typhoon Thad (198112) 的生命史始 at Northwest Pacific洋面, 整体路径呈现典型的“NW—NE”抛物线型转 toward 特征. formed初期 (8月16日至17日) , 系统位 at lat 19.6°至20.4°N, 131.8°至133.1°之间, 主要 toward NW direction缓慢Moving. 随后, 受副热带高压引导气流影响, Typhoon 逐渐转为N, 并在8月18日至19日期间维持较为稳定的N上Trend, The latitude从21.5°N迅速推进至25.1°N.
The key turn toward point appeared between August 20 and 21. During this period, after the Typhoon center crossed the lat 26° line, the Moving direction gradually shifted from N to NE direction. After August 22, as the latitude continued to rise to 30°N by N, the system accelerated toward NE, finally on August 23 Go to High latitude waters, at the end point at lat 49.3°N, 140.7° near. During the entire life cycle, the Typhoon did not landfall any land, has always been active at sea, the pathway span is extremely large, from the low latitude tropical waters has been extending to the mid-high latitude W wind zone.
在Intensity变化方面, Typhoon Thad经历了完整的“增强—巅峰—减弱”过程. 初始阶段为Nameless (17m/s) , 随后在48h内快速加强, at 8月18日凌晨达到Typhoon 级别 (33m/s) . 经过约一天的持续增强, 系统在8月19日12时达到peak intensity, 此时Max Wind为43m/s, 等级判定为Severe Typhoon. 巅峰状态维持Time较短, 随后Intensity开始波动下降. 8月20日至22日, 虽然wind speed维持在35-41m/s的Typhoon 级别, 但整体呈缓慢减弱Trend. Go to 8月23日后, 随着系统深入高The latitude冷海区, intensity 急剧衰减, 迅速降格为Severe Tropical Storm及Tropical Storm, 最终消散.
Compared to History, the Peak intensity of Thad in 1981 (Severe Typhoon, 43m/s) was weak at 15th Typhoon Thad (Super Typhoon) in 1984, but strong at 3rd Typhoon Thad (Typhoon) in 1988.
