Typhoon Iris, international code 197619, international name IRIS, 1976 Northwest Pacific typhoon. Formed: 1976-09-14 00:00:00, ended: 1976-09-29 12:00:00. Peak intensity: Typhoon , minimum central pressure: 975 hPa, max wind: 38m/s.
Typhoon Iris at 1976-09-14 00:00:00 at 15.7°N, 118.4°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Typhoon intensity with max winds of 38 m/s (~137 km/h) and a minimum central pressure of 975hPa, recorded at 1976-09-18 12:00:00.
1976-09-29 12:00:00 After, Typhoon Iris gradually weakened and was numbered off on 1976-09-29 12:00:00 was numbered off; its lifecycle recorded 63 track points.
Typhoon Iris (197619) 的生命史始 at Philippines以E洋面, 整体路径呈现显著的“W进-折返”复杂形态. formed初期 (9月14日至17日) , 系统受引导气流影响, 稳定 toward NW, 从15.7°N, 118.4°E逐渐逼近S海N部海域. 在9月19日达到最W端Position (21°N, 112.9°E) 后, 路径发生关键转折. 随后系统并未如典型秋台般继续深入内陆或N上, 而是在S海N部近海区域出现停滞并转 toward E移. 9月20日至21日期间, 其中心During从110.2°E回撤至108.9°E, 显示出明显的 toward W深入后的折返迹象. 9月22日后, 路径进一步 toward S调整至18.3°N附近, 随后在S海中部海域 (18°N-20°N, 110°E-113°E之间) 进行长Time的小范围回旋振荡. 直至生命末期, 系统才缓慢 toward NE direction漂移, 最终 at 9月29日在20.5°N, 113.4°E附近消散. 全生命周期长达15天半, 且全程无Landfall记录, 属 at 典型的远洋及近海回旋型Typhoon .
在Intensity变化方面, Iris经历了完整的“增强-巅峰-减弱-维持”过程. 系统从Nameless起步, 快速加强, at 9月17日发展为Typhoon 级别, 并在9月19日达到peak intensity, max wind 录得38m/s. 然而, 巅峰状态维持Time较短, Go to S海N部后迅速减弱, 9月20日降为Severe Tropical Storm, 次日即衰减为Nameless. 值得注意的是, 在随后的近一周Time内 (9月22日至29日) , 尽管系统结构松散, 但仍以Nameless形态在海上存活, wind speed维持在7-15m/s之间, 表现出较强的残余环流生命力.
Compared with the previous Typhoon, Iris' Intensity in 1976 was at a medium low level. Compared to the 1970 (Super Typhoon) and 1973 (Severe Typhoon) systems, its peak wind speed 38m/s was significantly weaker; but at the 1967 Tropical Storm level.
