Typhoon Dot, international code 198905, international name DOT, 1989 Northwest Pacific typhoon. Formed: 1989-06-02 06:00:00, ended: 1989-06-11 12:00:00. Peak intensity: Super Typhoon, minimum central pressure: 955 hPa, max wind: 51m/s.
Typhoon Dot at 1989-06-02 06:00:00 at 3.9°N, 144.4°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Super Typhoon intensity with max winds of 51 m/s (~184 km/h) and a minimum central pressure of 955hPa, recorded at 1989-06-09 00:00:00.
1989-06-11 12:00:00 After, Typhoon Dot gradually weakened and was numbered off on 1989-06-11 12:00:00 was numbered off; its lifecycle recorded 38 track points.
Typhoon Dot (198905) 的生命史始 at Northwest Pacific低The latitude海域, 整体呈现稳定的NW toward MovingTrend. formed初期 (6月2日至4日) , 系统位 at lat 3.9°至8.7°N, 144.4°至133.1°之间, 主要 toward WN direction缓慢Moving. Go to 6月5日后, 随着纬度提升至10°N以N, 其Moving路径逐渐转 toward NW, 横穿Philippines以E洋面. 值得注意的是, 该Typhoon 在整个生命周期内未发生明显的路径转折或回旋, 始终保持较为线性的NW行进路线, 最终 at 6月11日在N部湾附近减弱消散. 尽管路径直指陆地边缘, 但根据观测记录, Dot全程无Landfall记录, 主要在海上活动, 其路径终点位 at lat 22°N, 105°附近, 显示其在接近中S半岛coastal 时已显著减弱并改变性质.
Dot的Intensity演变经历了典型的“缓慢增强-爆发式加强-快速减弱”过程. 从6月2日的Nameless (10m/s) 起步, 系统经过约4天的酝酿, at 6月6日发展为Tropical Storm. 随后Go to 快速增强期, 特别是在6月8日至9日期间, 中心附近Max Wind从33m/s急剧攀升至51m/s, 达到Super Typhoon级别, 这也是其生命史中的巅峰时刻. 然而, 巅峰状态维持Time极短, 仅约半天后, 受环境因素影响, intensity 迅速回落. 6月9日18时已降为Severe Typhoon (48m/s) , 至6月10日中午进一步 weakened into Severe Tropical Storm (30m/s) , 并在最后两天内持续衰减为Nameless.
在与同名Typhoon 的横 toward 对比中, 1989年Dot的peak intensity (51m/s, Super Typhoon) 显著高 at 1990年, 1993年及1982年的同名Typhoon (均为Typhoon ), 但与1985年Dot (同为Super Typhoon) 处 at 同一Intensity量级. 这表明在“Dot”这一命名序列中, 1989年与1985年的系统具备更强的能量释放潜力, 而其余年份的同名Typhoon Intensity相对较弱.
