Typhoon Merbok trajectory
Path and Moving Characteristics
Typhoon Merbok, the 27th typhoon of 2004, had a relatively short life cycle, lasting only about 42h from formation to dissipation. According to observational data, its overall movement followed a stable westward path with a slight northward trend. During the initial stage, from 18:00 on November 21 to 06:00 on November 22, the system center remained at a latitude of approximately 15.6°N to 15.7°N, while its longitude moved rapidly westward from 124.9°E to 122.5°E, indicating strong westward steering flow. Its path then showed a slight increase in the northward component, with the center gradually moving north to 17°N. Throughout its life cycle, the typhoon did not undergo any obvious recurvature or loop, and its track was smooth and continuous. Notably, although its path crossed waters east of the Philippines, the data show no recorded landfall. It eventually weakened and dissipated near 119.2°E, making it a typical remote-ocean-passage tropical cyclone.
Intensity Evolution Analysis
Merbok的Intensity变化经历了“快速增强—维持巅峰—迅速减弱”三个典型阶段. formed初期为Tropical Depression, Pressure1006hPa, max wind 10m/s. 在随后的18h内, 系统经历显著加强过程, 气压降至最低值998hPa, wind speed提升至18m/s, at 11月22日12时达到Tropical Storm级别. 巅峰状态维持了约12h (11月22日12时至23日00时) , 期间气压稳定在998hPa, wind speed保持18m/s不变, 表明此时系统结构相对稳定, 能量收支平衡. 然而, 自11月23日06时起, intensity 开始回落, 气压回升至1000hPa, wind speed降为15m/s, 重新降级为Tropical Depression, 直至生命史结束. 这种短生命期, 弱Intensity的特征, 反映了其所在环境可能缺乏持续的能量供给或受到垂直风切变的不利影响.
Same-Name Comparison
Compared with previous typhoons bearing the same name, the 2004 Merbok was clearly weaker. Its peak intensity was only tropical storm strength, with a pressure of 998hPa and wind speed of 18m/s. By contrast, the 2011 Merbok, 201110, and the 2017 Merbok, 201702, both reached severe tropical storm strength, with minimum pressures of 980hPa and 984hPa, respectively. The 2022 Merbok, 202213, developed further to typhoon strength, with a minimum pressure of 965hPa. The data show that the 2004 Merbok was the weakest of recent typhoons with this name. Its peak wind speed was far below the average for same-named typhoons in other years, making it a relatively weak tropical cyclone.
