The features include\r\ninternal waves, thermohaline intrusions, and details of fronts. In practice, regional models\r\npredict internal tides at many locations, but the nonlinear steepening of these waves and\r\ntheir conversion to short nonlinear waves is often improperly modeled, because\r\ncomputationally prohibitive nonhydrostatic pressure is needed. To include the small-scale\r\ninternal waves of tidal origin, a nested hybrid model is under development. The approach\r\nis to extract long-wavelength internal tide wave information from tidally forced regional\r\nmodels, use ray methods or mapping methods to determine internal-tide propagation\r\npatterns, and then solve two-dimensional high-resolution nonhydrostatic wave models to\r\n\u201cfill-in\u201d the internal wave details. The resulting predicted three-dimensional environment\r\nis then input to a fully three-dimensional parabolic equation acoustic code.
