Observation of Typhoon Trami(2024)-induced energy cascade from near-inertial waves to diurnal internal tides
台风期间内波间的能量传递特征及机制尚未得到清晰揭示.本研究利用2024年南海北部"潭美"台风期间获取的高分辨率潜标观测数据,发现全日内潮与近惯性内波之间存在显著的垂直能量串级现象.台风作用下,观测发现在近惯性波能量显著增强的同时,全日内潮能量亦出现激增;在120-170米深度范围的水层,观测到台风强迫下近惯性波向全日内潮的平均净能量传递率达1 × 10-7 Wkg-1.双谱分析结果进一步证实,这一能量传递过程由非线性波-波相互作用主导驱动.上述结果揭示了"大气强迫至全日内潮"这一全新的内波能量传递路径,进而重新界定了极端天气事件作用下内波能量的再分配规律.
