Typhoon Forrest, international code 198930, international name FORREST, 1989 Northwest Pacific typhoon. Formed: 1989-10-18 00:00:00, ended: 1989-10-30 00:00:00. Peak intensity: Severe Typhoon, minimum central pressure: 940 hPa, max wind: 48m/s.
Typhoon Forrest at 1989-10-18 00:00:00 at 5°N, 157.8°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Severe Typhoon intensity with max winds of 48 m/s (~173 km/h) and a minimum central pressure of 940hPa, recorded at 1989-10-27 00:00:00.
1989-10-30 00:00:00 After, Typhoon Forrest gradually weakened and was numbered off on 1989-10-30 00:00:00 was numbered off; its lifecycle recorded 49 track points.
Typhoon Forrest (198930) 的生命史始 at 1989年10月18日, formed at Northwest Pacific低The latitude海域 (5°N, 157.8°E) . 在初始阶段, 系统呈现明显的W行Trend, 从10月18日至20日, 其Center由lng 157.8° toward WMoving至154.2°, 纬度略有S压. 自10月21日起, 路径发生显著转折, 受引导气流影响, Typhoon 转为 toward NW, 并逐渐加速. 这一NW行进态势持续至10月27日, 期间During从151.7°E快速W进至137.7°E, 纬度则N抬至22.7°N.
It is worth noting that between October 27 and 28, after the Typhoon reached lat 22.7°N, near 137.7°, the Moving direction changed critically, by NW turning toward NE. Subsequently, the system moved at a faster speed toward High latitude waters, and finally at October 30 reached lat 45.7°N, 163.6° of the ocean region.
在Intensity变化方面, Forrest经历了完整的 formed, 发展, 巅峰及衰减过程. 初期作为Nameless, wind speed维持在7-15m/s之间. 10月23日增强为Tropical Storm, 随后迅速加强, at 10月25日达到Typhoon 级别 (38m/s) . 10月26日至27日是其Intensity的巅峰期, max wind 达到48m/s, 定性为Severe Typhoon, 此时中心位 at lat 22.7°附近. 巅峰状态维持约24h后, 随着The latitude升高及Go to 高纬冷海区, intensity 开始减弱. 10月29日降级为Severe Tropical Storm (30m/s) , 直至生命末期仍保持此Intensity等级.
Data show that in 1992, 1986 and 1983 the same-name Typhoon peak intensity reached the 'Super Typhoon' level, while in 1980 it was 'Severe Tropical Storm'. 1989 Forrest's peak intensity is 'Severe Typhoon', between 1980 and the other three Super Typhoon years, showing a large annual difference of Typhoon Intensity under the name sequence, but overall, 1989 case did not reach the most intense level in the history of the name.
