Typhoon Winnie, international code 199711, international name WINNIE, 1997 Northwest Pacific typhoon. Formed: 1997-08-05 00:00:00, ended: 1997-08-23 00:00:00. Peak intensity: Super Typhoon, minimum central pressure: 915 hPa, max wind: 71m/s.
Typhoon Winnie at 1997-08-05 00:00:00 at 5.6°N, 168°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Super Typhoon intensity with max winds of 71 m/s (~256 km/h) and a minimum central pressure of 915hPa, recorded at 1997-08-12 00:00:00.
Typhoon Winnie gradually weakened and was numbered off on 1997-08-23 00:00:00 was numbered off; its lifecycle recorded 73 track points.
Typhoon Winnie (199711) 的生命史长达18天, 其路径呈现出典型的NW行进而后转 toward NE的抛物线形态. formed初期, 系统位 at W太平洋低The latitude海域 (5.6°N, 168°E) , 随后稳定 toward NW. 在8月5日至8月12日期间, Typhoon 中心纬度从5.6°N迅速N抬至18°N, During由168°EW进至144.9°E, 显示出强劲的NW推进动力.
路径的关键转折点出现在8月中旬. 随着The latitude继续N抬, Moving direction逐渐由NW转为N, 进而转 toward NE. 8月18日位 at (28.2°N, 121.4°E) 时, 系统仍维持Typhoon Intensity, 随后加速 toward NE, 穿越较高纬度海域. 最终 at 8月23日在47.2°N, 135.5°E附近消散. 整个过程中, 该Typhoon 未记录到Landfall行为, 主要在开阔洋面上活动, 路径平滑且连续, 涵盖了从Nameless到Super Typhoon再到温带气旋转化的完整生命周期.
Winnie's Intensity evolution experienced rapid enhancement, peak maintenance and slow weakening in three phases. After developing into Tropical Storm on August 9, the intensity sharply climbed, and in less than two days Time reached Super Typhoon level (51m/s) on August 11 . on August 12 at 12:00, which reached life history peak near (18°N, 144.9°E), max wind up to 71m/s, confirmed as Super Typhoon.
Go to High latitude, influenced by the environmental field, intensity began to decline continuously. August 15 decreased to Severe Typhoon, August 17 further weakened into Typhoon. August 20, when the system Moving to 35.4°N, has degraded to Nameless, and finally dispersed at 40 degrees to the Shanghai region.
Looking back to the four 'Winnie' Typhon in 1966, 1969, 1972 and 1978, its peak intensity is only Severe Tropical Storm level.
