The SummaryTyphoon Iris (international code 196426) is a 1964 Northwest Pacific typhoon; peak intensity Typhoon, max wind 33m/s, minimum central pressure 996hPa, not in China Landfall, 1964-11-04 was numbered off, recorded 9 track points.
Typhoon Iris, international code 196426, international name IRIS, 1964 Northwest Pacific typhoon. Formed: 1964-11-02 12:00:00, ended: 1964-11-04 12:00:00. Peak intensity: Typhoon , minimum central pressure: 996 hPa, max wind: 33m/s.
Typhoon Iris at 1964-11-02 12:00:00 at 13.7°N, 114.8°E over the Northwest Pacific; initial intensity: Tropical Storm.
It peaked at Typhoon intensity with max winds of 33 m/s (~119 km/h) and a minimum central pressure of 996hPa, recorded at 1964-11-04 00:00:00.
1964-11-04 12:00:00 After, Typhoon Iris gradually weakened and was numbered off on 1964-11-04 12:00:00 was numbered off; its lifecycle recorded 9 track points.
Typhoon Iris (196426) 的生命史相对短暂, 主要活动区域位 at S海中W部海域. 从路径采样数据来看, 该Typhoon 整体呈现稳定的WN至正WTrend. formed初期 (11月2日12时至11月3日00时) , 系统中心位 at lat 13.7°至14.3°N, 114.8°至113.6°之间, Moving direction主要为NW toward , The latitude缓慢抬升, During持续W移.
It is worth noting that between 06:00 and 12:00 on November 3, the typhoon track showed a noticeable turn toward feature.After the peak of the latitude reached 14.8°N, the system began toward S twisting, then turning to the Moving path of almost W. On November 3, 18 to 12:00 on November 4, the central latitude gradually dropped from 14.2°N to near 13.8°N, while the length moved from 110.4°E fast W to 108.3°E. Thro the process, the Typhoon did not touch any land, no Landfall records, alwaysined life history at sea until disintegrated.
在Intensity变化方面, Iris经历了一个典型的“增强-巅峰-迅速减弱”过程. 初始阶段为Tropical Storm (23m/s) , 维持约18h后, at 11月3日06时 intensified into Severe Tropical Storm (25m/s) . 随后Intensity持续攀升, 12时wind speed达28m/s, 18时增至30m/s. 11月4日00时, 系统达到peak intensity, 升级为Typhoon intensity with max winds of 录得33m/s, 并在随后的6h内维持这一Intensity. 然而, 其巅峰状态极为短暂, 11月4日12时观测数据显示, 系统已迅速 weakened into Nameless (17m/s) , 表明其在生命末期遭遇了不利的环境条件或内部结构崩溃.
Compared with previously identified Typhoon, the 1964 Iris's Intensity was at a medium downward level. Compared with the 1970 Iris (Super Typhoon), 1973 Iris (Severe Typhoon) and 1976 Iris (Typhoon), the 1964 system's peak intensity was only the ordinary Typhoon level, and Max Wind33m/s low at the following most typical Typhoon's Intensity. Compared only to the 1967 Iris (Tropical Storm), the 1964 system's Intensity was slightly higher.
