The SummaryTyphoon Iris (international code 195903) is a 1959 Northwest Pacific typhoon; peak intensity Severe Typhoon, max wind 46m/s, minimum central pressure 965hPa, not in China Landfall, 1959-08-23 was numbered off, recorded 20 track points.
Typhoon Iris, international code 195903, international name IRIS, 1959 Northwest Pacific typhoon. Formed: 1959-08-19 00:00:00, ended: 1959-08-23 18:00:00. Peak intensity: Severe Typhoon, minimum central pressure: 965 hPa, max wind: 46m/s.
Typhoon Iris at 1959-08-19 00:00:00 at 16.2°N, 128.4°E over the Northwest Pacific; initial intensity: Tropical Storm.
It peaked at Severe Typhoon intensity with max winds of 46 m/s (~166 km/h) and a minimum central pressure of 965hPa, recorded at 1959-08-22 00:00:00.
1959-08-23 18:00:00 After, Typhoon Iris gradually weakened and was numbered off on 1959-08-23 18:00:00 was numbered off; its lifecycle recorded 20 track points.
Typhoon Iris (195903)'s life begins at the Northwest Pacific ocean surface, the overall path presents a typical NW toward MovingTrend, eventually deep intoland dispersal. From formed early August 19 00, 16.2°N, 128.4°E) to the peak, the system mainlyins WN, latitude slowly rising, length continues to W. During the August 20-21 period, as the system Intensity increases, its toward N percentage gradually increases, the path curvature changes, from pure W toward toward to more significant NW toward.
The Typhoon did not record the Landfall process, but its path was close to the EAC coastal. On August 22, at 6 p.m., the system reached the nearest point of the N-end (21.4°N, 120.2°E), then continued toward NW direction deep, through the W-side waters of the Taiwan Strait Go to China Continental SEcoastal region. After August 23, the Moving speed accelerated and direction further oriented toward N to NE, finally at August 23, at 18 p.m. at 30.5°N, 108°E weakened into Nameless and ended the observation.
Iris的Intensity演变经历了“快速增强—巅峰维持—迅速减弱”的典型过程. formed初期为Tropical Storm (23m/s) , 在约36h内迅速 intensified into Typhoon (35m/s) . 8月21日18时起, 系统升级为Severe Typhoon, 并 at 8月22日00时至06时达到peak intensity, max wind 达46m/s. 值得注意的是, 巅峰状态维持Time较短, 仅约12h后, 随着系统N上靠近陆地, intensity 开始急剧下滑. 从8月22日12时的41m/s降至8月23日06时的20m/s, 短短18h内wind speed减半, 显示出Landfall或近岸后能量耗散极快.
Compared to the previous typhoon, the peak intensity (Severe Typhoon, 46m/s) of Iris in 1959 was at a medium level. Compared to the 1970s Iris (Super Typhoon) and the 1973s Iris (Severe Typhoon) , its intensity was slightly weaker; but markedly strong at the 1967s Iris (Tropical Storm) . Compared to the 1976s Iris (Typhoon ) was close, but the 1959 system had a slight advantage on peak wind speed.
