The SummaryTyphoon Wanda (international code 197401) is a 1974 Northwest Pacific typhoon; peak intensity Severe Tropical Storm, max wind 28m/s, minimum central pressure 992hPa, not in China Landfall, 1974-01-14 was numbered off, recording 23 track points.
Typhoon Wanda, international code 197401, international name WANDA, 1974 Northwest Pacific typhoon. Formed: 1974-01-09 00:00:00, ended: 1974-01-14 12:00:00. Peak intensity: Severe Tropical Storm, minimum central pressure: 992 hPa, max wind: 28m/s.
Typhoon Wanda at 1974-01-09 00:00:00 at 8.6°N, 129.7°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Severe Tropical Storm intensity with max winds of 28 m/s (~101 km/h) and a minimum central pressure of 992hPa, recorded at 1974-01-10 18:00:00.
1974-01-14 12:00:00 After, Typhoon Wanda gradually weakened and was numbered off on 1974-01-14 12:00:00 was numbered off; its lifecycle recorded 23 track points.
Typhoon Wanda (197401) originated at the Northwest Pacific Ocean on January 9, 1974, at its initial position at lat 8.6°N, 129.7°. Thro its life cycle, the Typhoon presented a stable and continuous NE toward MovingTrend, with no apparent path toward or stagnant phenomenon.
By observing the track points sequence is known, Typhoon in the early January 9th to 10th mainly toward NNW direction slow Moving, then turn toward more significant NE direction. especially during the January 13th 12th to 14th, the length range significantly increased (from 147°E to 157°E) , indicating its influence by the high air guided flow, Moving speed accelerated.
在Intensity变化方面, Typhoon Wanda经历了典型的“快速增强-短暂巅峰-持续减弱”过程. 系统初生时为Nameless, wind speed12m/s; 经过约30h的加强, at 1月10日00时升级为Tropical Storm, 并在同日18时达到生命史中的peak intensity, 确认为Severe Tropical Storm, max wind 录得28m/s. 值得注意的是, 其巅峰状态维持Time较短, 仅数h后便从1月11日00时开始Go to 减弱通道, 迅速降级为Tropical Storm, 并 at 1月11日12时回落至Nameless等级. 此后直至消散, 其Intensity一直维持在Nameless水平 (wind speed12-15m/s) , 结构趋 at 松散.
The data show that in 1962 Wanda had reached the Severe Typhoon level, in 1971 Wanda had reached the Typhoon level, and in 1977 Wanda was only the Tropical Storm. In 1974, although Wanda had reached the Severe Tropical Storm level, in 1977, but far less than in 1962 and 1971, the intensity level.
