Typhoon Mac, international code 199025, international name MIKE, 1990 Northwest Pacific typhoon. Formed: 1990-11-06 00:00:00, ended: 1990-11-18 12:00:00. Peak intensity: Super Typhoon, minimum central pressure: 915 hPa, max wind: 77m/s.
Typhoon Mac at 1990-11-06 00:00:00 at 6.5°N, 151.9°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Super Typhoon intensity with max winds of 77 m/s (~277 km/h) and a minimum central pressure of 915hPa, recorded at 1990-11-10 18:00:00.
1990-11-18 12:00:00 After, Typhoon Mac gradually weakened and was numbered off on 1990-11-18 12:00:00 was numbered off; its lifecycle recorded 51 track points.
Typhoon Mac (199025) 的生命史始 at 1990年11月6日, formed at Northwest Pacific低The latitude海域 (6.5°N, 151.9°E) . 在初始阶段, 系统呈现稳定的W行Trend, 从11月6日至11月11日期间, 其纬度基本维持在6.7°N至8.7°N之间, During则由151.9°E快速W移至133.5°E, 显示出强劲且持续的W引导气流作用. 11月12日后, 路径出现显著转折, Typhoon 开始 toward NW, 纬度逐渐N抬. Go to 11月14日至18日的后半段生命周期, Moving direction进一步转为NNW, 最终 at 11月18日12时消散 at 22.4°N, 107°E附近. 整个路径跨度极大, 横跨超过40个经度, 且全程无Landfall记录, 始终在海上活动, 直至在Vietnam以E近海区域减弱消散.
该Typhoon 经历了极为迅猛的增强过程. 从11月6日的Nameless (7m/s) 起步, 仅用3天Time便 at 11月9日发展为Typhoon (35m/s) . 随后Intensity爆发式增长, 11月10日达到Super Typhoon级别 (56m/s) , 并 at 11月11日在8.1°N, 133.5°E附近达到peak intensity, max wind 高达77m/s. 巅峰状态维持约2天后, 自11月13日起开始持续减弱, wind speed由53m/s逐步降至11月18日的10m/s. 尽管后期Intensity大幅衰减, 但其在低The latitude长Time维持Super Typhoon等级, 体现了极高的能量密度.
In 1989 Mac (198914) peaked only typhoon level, 1979 Mac (197913) also typhoon level, and 1986 Mac (198604) only reached Tropical Storm level. in contrast, 1990 Mac not only reached Super Typhoon level, and 77m/s peak wind speed far over other years of the same name typhoon, is the most intense time in this naming series.
