| Zusammenfassung |
| Spatio-temporal evolution of rogue waves measured in Taiwanese coastal
waters is reconstructed by means of numerical simulations. Their lifetimes
are up to 100 s. The time series used for reconstructions were measured at
dimensionless depths within the range of kh = 1.3–4.0, where k is the
wave number and h is the depth. All identified rogue waves are surprisingly
weakly nonlinear. The variable-coefficient approximate evolution equations,
which take into account the shoaling effect, allow us to analyze the
abnormal wave evolution over non-uniform real coastal bathymetry. The
shallowest simulated point is characterized by kh ≈ 0.7. The
reconstruction reveals an interesting peculiarity of the coastal rogue
events: though the mean wave amplitudes increase as waves travel onshore,
rogue waves are likely to occur at deeper locations, but not closer to the
coast. |
