A nonlinear Green's function approach to the quasigeostrophic winddriven flow over sloping bottom topography

TL;DRAbstract

Varying bottom topography is an important factor affecting the dynamics of an ocean. It can be the source of waves and eddies and can influence in this way the vertical and the horizontal mass transport and mixing processes. A well known example is the irradiation of internal and inertial waves at isolated topographic features as seamounts, ridges or valleys. Moreover, if the stratification is not too strong, topographic waves can penetrate up to the surface. On oceanic scales sloping bottom is the source of Rossby waves in the spectrum of an oceanic basin. Another aspect of the influence of the bottom topography on the ocean dynamics is the bottom form stress. Considering the momentum balance of an ocean, i.e. which forces balance the momentum impact due to the wind, it turns out that the so called bottom form stress can play an important role. This is especially the case within a long or periodic channel, where no along-channel pressure gradients can balance the alongchannel momentum
