Typhoon Peggy, international code 198917, international name PEGGY, 1989 Northwest Pacific typhoon. Formed: 1989-08-14 18:00:00, ended: 1989-08-19 06:00:00. Peak intensity: Nameless, minimum central pressure: 996 hPa, max wind: 17m/s.
Typhoon Peggy at 1989-08-14 18:00:00 at 15.8°N, 145.2°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Nameless intensity with max winds of 17 m/s (~61 km/h) and a minimum central pressure of 996hPa, recorded at 1989-08-16 12:00:00.
1989-08-19 06:00:00 After, Typhoon Peggy gradually weakened and was numbered off on 1989-08-19 06:00:00 was numbered off; its lifecycle recorded 19 track points.
Typhoon Peggy (198917) 的生命周期始 at 1989年8月14日18时, formedPosition位 at lat 15.8°N, 145.2°的Northwest Pacific洋面. 在初始阶段, 该系统呈现稳定的NW toward MovingTrend. 从8月14日至8月16日06时, 其The latitude由15.8°N迅速N抬至20.4°N, During由145.2°EE移缓慢推进至148.8°E, 表明引导气流主要推动其 toward NW direction行进.
The typhoon's notable feature is at its apparent turn toward at about 12 a.m. on August 16th. Before this, the entire path is inclined toward NW; while at lat 21.5°N, 148.7° near, the Moving direction gradually turns to W, then further adjusted to WSW direction. Especially during August 17th at 06 a.m. to August 19th, the Typhoon's center latitude changes slowly (from 23.3°N to 24.6°N), while the length is significantly toward W retreat (from 147.6°E to 142.0°E) . This 'pre-NW, after turning back to SW/W' path form, constitutes a rather reverse clock or retreat structure, ultimately at August 1906 at 24.6°N, weakened near 14
In terms of intensity, Typhoon Peggy (198917) overallined a weaker level, the whole course was only qualified as Nameless. its Max Wind reached a peak of 17m/s on August 16 at 12 andined about 48h on this Intensity (up to August 18 at 00) . Since then, the system Go to continuous weakening phase, wind speed from 17m/s gradually to 10m/s, until the end of life to 7m/s. by at lack of air pressure data support, can only be judged by wind speed its failure to develop into Tropical Storm and above.
与同名History相比, 1989年的PeggyIntensity显著偏弱. 数据显示, 1994年Peggy (199402) 曾达到Severe Typhoon级别, 1990年Peggy (199028) 与1986年Peggy (198607) 更是达到了Super Typhoon级别. 相比之下, 198917号Peggy不仅peak intensity仅为Nameless, 且生命周期较短 (约4.5天) , track points仅19个, 显示出其结构松散, 能量积累不足的特征, 属 at “Peggy”命名序列中Intensity最弱, 影响范围最小的个案之一.
