Typhoon Nat, international code 199119, international name NAT, 1991 Northwest Pacific typhoon. Formed: 1991-09-15 00:00:00, ended: 1991-10-02 06:00:00. Peak intensity: Super Typhoon, minimum central pressure: 950 hPa, max wind: 56m/s.
Typhoon Nat at 1991-09-15 00:00:00 at 19.5°N, 124°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Super Typhoon intensity with max winds of 56 m/s (~202 km/h) and a minimum central pressure of 950hPa, recorded at 1991-09-22 06:00:00.
1991-10-02 06:00:00 After, Typhoon Nat gradually weakened and was numbered off on 1991-10-02 06:00:00 was numbered off; its lifecycle recorded 70 track points.
Typhoon Nat (199119) 的生命史长达17天以上, 其Moving路径呈现出显著的复杂性与回旋特征. formed初期, 系统位 at Philippines以E洋面 (124°E附近) , 整体 toward WMoving并一度深入至118.5°E附近. 随后, 受大气环流引导, 路径发生显著转折, at 9月20日至22日期间 toward E回流至125.6°E附近, 完成了一次大尺度的逆时针回旋. 在达到生命史最E端后, Typhoon 再次转 toward W行, 并 at 9月23日左右逼近我国SEcoastal 区域. Go to 9月下旬, 系统在S海N部及Taiwan海峡S部海域徘徊, 路径呈现SN toward 摆动, 直至9月底才重新确立 toward NE的Trend, 最终在Fujian以E海域减弱消散. 全生命周期内无Landfall记录, 主要活动范围集中 at 15°至26°N, 116°至126°之间的广阔海域.
该Typhoon 的Intensity变化剧烈, 经历了从Nameless到Super Typhoon的完整发展过程. 初始阶段Intensity较弱, 维持在Nameless至Tropical Storm级别. 9月21日后迅速增强, 仅用约一天Time便由Typhoon 级 (35m/s) 跃升至Super Typhoon级, at 9月22日12时达到peak intensity, max wind 录得56m/s. 然而, 巅峰状态维持Time较短, 随后受环境因素影响快速减弱, 至9月25日已降级为Tropical Storm. 值得注意的是, 系统在9月底至10月初出现了罕见的“二次加强”现象, 从Nameless重新发展为Typhoon 级 (33m/s) , 显示出后期能量补充的特征.
Data showed that the 1994 Typhoon peak intensity of the same name was only Tropical Storm, while the 1991 Nat not only reached the Super Typhoon level, and Max Wind at 56m/s, both of which had substantial differences in the upper intensity.
