The effect of rotation on shoaling internal solitary waves in the northern South China Sea
The propagation of large amplitude internal solitary waves (ISWs) in the northern South China Sea (SCS) is simulated using the fully nonlinear,nonhydrostatic MIT general circulation model (MITgcm).Special attention is paid to the effects of rotation and the shoaling three-dimensional topography.It is found that for the conditions of the northern SCS,with constant depth a state of decay-reemergence process is reached.However,instead of the formation of a final localized wave packet,the frontal waves constantly attenuate by repeatedly shedding inertia-gravity waves backwards.Under the combined effects of shoaling topography and rotation,a very pronounced secondary wave train is formed near the shelf break,and it is much more remarkable in the northern cross-sections.The secondary wave train vanishes when rotation is switched off.Three-dimensional ISW shoaling experiment is performed,and the evolution of wavefronts and wave profiles are scrutinized.Spatial inhomogeneity of wave distribution is notable and the influence of rotation is re-visited..
