The generation of internal waves by flow over the rough topography of a continental slope

摘要: Internal gravity waves generated as standing lee by the flow, V , of a uniformly stratified fluid over small-scale topography on an inclined slope are examined in particular case which flow is parallel to mean isobaths. Attention given magnitude and direction energy flux its dependence Vl / N α β where l wavenumber topography, buoyancy frequency fluid, defines orientation two-dimensional slope. In general there greater probability transfer towards shallow water, but regions depends For scale for fixed longslope current, stratification, drag associated with greatest when = 0 (when oriented normal isobaths) it can be large turbulent stress sea bed. The may induce variations currents surface. It found that although stationary formed sloping reflected at surface subsequently scattered from produce propagate flow.
