Typhoon Winnie Trail Characteristics
Track and Movement Characteristics
Typhoon Winnie (199711) 的生命周期长达14天, 整体路径呈现典型的NW toward Moving后转 toward NE的抛物线形态. formed初期 (8月8日至10日) , 系统在低纬度海域 (11.2°N-15.4°N) 稳定 toward NW, 经度从158.9°EW移至153.8°E. 8月11日至13日为快速增强期, 路径维持WNW走 toward , Pressure急剧下降至920hPa, 达到Super Typhoon级别.
Notably, after reaching its peak intensity on August 13, the system's movement gradually shifted from NW to due N, then turned clearly toward NE after August 17. August 19 marked a critical turning point, when the system was near 30°N, 119°E. It subsequently accelerated toward NE and crossed higher-latitude waters. It did not dissipate until August 22 near 45.8°N, 131°E, having made no landfall and remaining mainly over the open ocean throughout. This long, extensive track indicates that it was significantly influenced at different stages by the steering flow of the subtropical high and the flow ahead of a trough in the westerlies.
Intensity evolution and historical comparison
Winnie exhibited both explosive intensification and gradual weakening. It developed from a tropical depression on August 8 (10m/s, 1006hPa) into a super typhoon on August 13 (60m/s, 920hPa) in just 5 days. The central pressure fell by 86hPa and the wind speed increased by 50m/s, indicating highly favorable conditions for energy uptake. Its peak intensity was brief, with intensity beginning to fluctuate and decline on August 14, but it remained a severe typhoon through August 16 (45m/s, 950hPa). After moving to higher latitudes, it weakened rapidly under the influence of cold sea waters and vertical wind shear. It was downgraded to a severe tropical storm on August 19 and ultimately dissipated as a tropical storm over temperate waters.
与历史同名Typhoon 相比, 1997年Winnie的Intensity远超以往记录. 1966年至1978年间四次名为“Winnie”的Typhoon 中, 最强者为1966 Typhoon (最低气压973hPa) , 其余均为Severe Tropical Storm级别 (最低气压在975hPa-988hPa之间) . 1997年Winnie的最低气压 (920hPa) 比历史最强同名Typhoon 低了53hPa, max wind 高出至少17m/s (基 at 1966 Typhoon 上限估算) , 是同名序列中破坏潜力最大, Intensity最高的一个系统.
