Web29 de dez. de 2015 · The South China Sea is another ocean area where very large-amplitude and long-crested solitary internal waves are encountered (e.g., Liu et al., 1998), probably the largest in the world’s ocean.They are generated by the interaction of the tidal current with shallow underwater bottom topography located in the Luzon Strait (between … WebThe shallow-water wave velocity c = ( g h) 1 / 2 can only predict the arrival time of the early signals accurately but can hardly estimate that of ridge-trapped waves. The present study provides a fast analytic prediction method to estimate the arrival time of the subsequent large trapped waves.
