Typhoon Wynne, international code 198706, international name WYNNE, 1987 Northwest Pacific typhoon. Formed: 1987-07-20 12:00:00, ended: 1987-08-01 12:00:00. Peak intensity: Super Typhoon, minimum central pressure: 920 hPa, max wind: 64m/s.
Typhoon Wynne at 1987-07-20 12:00:00 at 4.3°N, 178.9°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Super Typhoon intensity with max winds of 64 m/s (~230 km/h) and a minimum central pressure of 920hPa, recorded at 1987-07-26 06:00:00.
1987-08-01 12:00:00 After, Typhoon Wynne gradually weakened and was numbered off on 1987-08-01 12:00:00 was numbered off; its lifecycle recorded 49 track points.
Typhoon Wynne (198706)'s history began at 12 a.m. on July 20, 1987, in the Northwest Pacific Ocean, at its initial position at 4.3°N, 178.9°E. During the period formed from the beginning to July 26, the system mainly showed a stable NW toward MovingTrend.
路径的显著转折点出现在7月27日至28日之间. 7月27日12时, Typhoon 中心位 at 21.3°N, 136.8°E, 随后 at 7月28日Moving至24.8°N, 133.2°E, 此时Moving direction逐渐由NW转为N. Go to 7月29日后, 路径发生明显NE toward 转折, Center从29.4°N, 132.4°E快速Moving toward 32.2°N, 138.3°E, 并最终 at 8月1日到达36.2°N, 154.2°E的高The latitude海域. 整个生命周期中, Wynne未Landfall任何陆地, 始终在洋面上活动, 最终在高纬度地区减弱消散.
Wynne的Intensity演变经历了快速增强, 巅峰维持及逐渐减弱三个阶段. 系统从Nameless起步, at 7月22日增强为Tropical Storm, 7月24日发展为Typhoon . 最为显著的爆发式增强发生在7月25日至26日, max wind 从56m/s跃升至64m/s, 达到Super Typhoon级别, 这也是其生命史中的peak intensity. 此后, Super Typhoon状态维持至7月28日, 期间wind speed虽略有波动 (61m/s至53m/s) , 但核心Intensity依然强劲. 7月29日起, 随着The latitude升高及环境场变化, intensity 开始显著衰减, 由Typhoon 级降为Severe Tropical Storm, 并最终在8月1日 weakened into Nameless.
Compared to the 1984 Wynne (198402) only reached the peak intensity of Severe Tropical Storm, in 1987 Wynne reached the higher Super Typhoon grade. although the 1980 Wynne (198019) is also recorded as Super Typhoon, but in 1987 Wynne with 64m/s Max Wind showed extremely strong destruction potential.
