The generation of internal tides by flat-bump topography

摘要: Abstract A general procedure for the calculation of oceanic internal tides generated by interaction surface tide with bottom topography is derived, and applied to typical cases. The formalism restricted here essentially two-dimensional whose never tangential local direction tidal energy propagation, but has otherwise arbitrary shape. theory applicable a wide range density stratifications which permits two-parameter fit any case. Results have been calculated certain representative topographic shapes, most notably continental slopes, these indicate that rate conversion into generally increases rapidly height, also depends strongly on geometry. For instance, this model, slopes are far more effective generators than, say, Mid-Atlantic Ridge. model ocean constant Brunt-Vaisala frequency, N, wave fluxes each side slope (satisfying above criteria) approximately equal, an realistic profile flux larger shallow shelf than in deep ocean.
