Abstract

A large amplitude solitary wave was detected simultaneously by using in-situ and remote sensing observations. A theoretical velocity field inferred from the observed density field associated with the internal solitary wave and the wind speed and direction was used to calculate the spatially varying surface wave spectra over the internal solitary wave. Employing a composite surface scattering model, the modulated wave spectra were converted into theoretical radar signatures. It is found that the observed and simulated variations of the normalized radar cross section agree quite well. This agreement results from an accurate knowledge of the whole set of parameters which determine the theoretical radar signature of the internal solitary wave. Several numerical simulations elucidate the dependence of the simulated radar signatures on wind conditions, namely wave amplitude, undisturbed interface depth, and relative density difference.
