Internal Gravity Waves at Abrupt Topography. ARI: Flow Over Abrupt Topography
Abstract
Research goals of this study include: Identification and modeling of the dynamical processes that determine the oceanic internal gravity wave spectrum, its evolution, and its variability; and Understanding the role that internal waves play in the redistribution and mixing of momentum, potential vorticity, heat and salt. Objectives were: Identification and modeling of the effects that irregular ocean bottom topography exerts on internal gravity waves; Determining the significance of these effects by comparison with other known processes; Testing the idea that reflection and scattering of internal gravity waves at bottom topography and the subsequent (nonlinear) adjustments enhance wave breaking and mixing near topography. Tasks completed were: Derivation of the scattering integral in the limit that (i) the height of the topography is smaller than the internal wave vertical wavelength; and (ii) the slope of the topography is smaller than the slope of the internal wave characteristic.
