Typhoon Cecil, international code 198904, international name CECIL, 1989 Northwest Pacific typhoon. Formed: 1989-05-22 00:00:00, ended: 1989-05-26 00:00:00. Peak intensity: Typhoon , minimum central pressure: 975 hPa, max wind: 38m/s.
Typhoon Cecil at 1989-05-22 00:00:00 at 11.7°N, 114.1°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Typhoon intensity with max winds of 38 m/s (~137 km/h) and a minimum central pressure of 975hPa, recorded at 1989-05-24 12:00:00.
1989-05-26 00:00:00 After, Typhoon Cecil gradually weakened and was numbered off on 1989-05-26 00:00:00 was numbered off; its lifecycle recorded 17 track points.
Typhoon Cecil (198904) 的生命周期始 at 1989年5月22日00时, 终 at 5月26日00时, 全程历时约4天. 从空间轨迹来看, 该Typhoon formed at S海中W部海域 (11.7°N, 114.1°E) , 整体呈现稳定的NW toward MovingTrend. 在初始阶段, 系统 toward WNW direction缓慢推进, During变化显著而The latitude增幅相对平缓. 随着Time推移至5月24日, 路径出现明显的转 toward 特征: 在达到最N端纬度15.8°N附近时, Moving direction逐渐由NW转为更偏 toward 正W及SW direction, 最终消散 at Vietnam以E海域 (17.8°N, 104.7°E) . 整个过程中, Typhoon 未发生Landfall, 始终在海上活动, 其路径平滑, 无剧烈折角或停滞现象, 显示出受稳定引导气流控制的特征.
Cecil的Intensity变化经历了完整的“ formed-增强-巅峰-减弱”过程. 5月22日上午, 系统由Nameless迅速 intensified into Tropical Storm, 并 at 当晚升级为Severe Tropical Storm. 5月23日至24日上午是其快速增强期, max wind 从25m/s攀升至38m/s, at 5月24日12时达到Typhoon 级别巅峰状态. 值得注意的是, 巅峰维持Time较短, 仅约6h后, 自5月24日18时起, 系统开始显著减弱, wind speed降至35m/s, 并在随后24h内迅速降级. 至5月25日00时, 已回落至Severe Tropical Storm级别, 随后进一步 weakened into Nameless, 直至最终消散. 这种快速增强后迅速衰减的模式, 反映了其生命史中能量获取与耗散的非对称性.
在“Cecil”这一命名序列的历史记录中, 1989年的这次Typhoon Intensity处 at 中等偏下水平. 其peak intensity仅为Typhoon 级 (38m/s) , 远低 at 1993年, 1985年及1982年的同名Typhoon , 后三者均达到了Super Typhoon级别, 显示出极强的破坏潜力. 相比之下, 1989年Cecil的Intensity略高 at 1990年的同名Typhoon (巅峰为Tropical Storm) . 这表明, “Cecil”这个名字所对应的Typhoon 个体间Intensity差异巨大, 既有极具威力的Super Typhoon, 也有如1989年这般Intensity有限, 未造成Landfall影响的普通Typhoon .
