摘      要：Internal waves arise in a wide array of oceanographic problems of both theoretical and engineering *** this contribution we present a newmodel,valid in the weakly nonlinear regime,for the propagation of disturbances along the interface between two ideal fluid layers of infinite extent and different ***,we present a novel high-order/spectral algorithm for its accurate and stable *** validation results and simulations of wave-packet evolution are provided.
