Typhoon Mac, international code 198914, international name MAC, 1989 Northwest Pacific typhoon. Formed: 1989-07-30 00:00:00, ended: 1989-08-08 12:00:00. Peak intensity: Typhoon , minimum central pressure: 950 hPa, max wind: 41m/s.
Typhoon Mac at 1989-07-30 00:00:00 at 23.5°N, 153°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Typhoon intensity with max winds of 41 m/s (~148 km/h) and a minimum central pressure of 950hPa, recorded at 1989-08-03 18:00:00.
1989-08-08 12:00:00 After, Typhoon Mac gradually weakened and was numbered off on 1989-08-08 12:00:00 was numbered off; its lifecycle recorded 39 track points.
Typhoon Mac (198914) 的生命周期始 at Northwest Pacific远洋海域, 整体路径呈现典型的“NW行后转NE”的抛物线型轨迹. formed初期 (7月30日至8月1日) , 系统位 at lat 20°至23.5°N, 151°至153°之间, 主要 toward WNW direction缓慢Moving, The latitude略有波动但During持续W进. 8月2日起, 随着系统Intensity提升, 其Moving速度加快并逐渐转 toward NW direction, 中心坐标从(24°N, 150.2°E)快速移至(26.8°N, 148.2°E).
A key turn toward point appeared between August 3 and August 5. During this period, the Typhoon center wandered around at 26° to 28°, stagnating in length from 145.4° EW to 143.9° E, and then began to significantly turn toward NE. On August 5th at 18:00, the system accelerated toward NE, the latitude rapidly climbing from 32.6° N to 47° N on August 8, eventually dispersing in higher latitudes.
该Typhoon 经历了完整的“ formed-发展-巅峰-衰减”过程. 7月30日以Nameless形式 formed, 初始wind speed10m/s. 经过约3天的缓慢增强, at 8月2日凌晨升级为Tropical Storm, 并在同日傍晚达到Severe Tropical Storm级别. 8月3日中午, 系统进一步 intensified into Typhoon , max wind 达到38m/s, 并在此Intensity维持至8月5日凌晨. 数据显示, 其巅峰状态持续约48h, 期间wind speed稳定在38m/s, 随后受高The latitude环境影响开始减弱. 8月5日傍晚wind speed降至35m/s, 8月6日中午降级为Tropical Storm, 最终 at 8月8日在47°N附近 weakened into Nameless并结束生命史.
与同名History相比, 1989年Mac的 peak intensity is Typhoon 级 (41m/sMax Wind记录) , 弱 at 1990年的Mac (Super Typhoon), 但强 at 1986年的Mac (仅达Tropical Storm). 与1979年同名Typhoon (Typhoon )相比, 两者巅峰等级相同, 但1989年Mac的Max Wind记录略高. 总体而言, 1989年Mac属 at 中等Intensity的远洋Typhoon , 其特点在 at 巅峰期维持Time较长且路径转 toward 清晰.
