A Topographic-Rossby Mode Resonance over the Iceland-Faeroe Ridge

An array of current-meter moorings along 12W on the southern side of the IcelandFaeroe Ridge reveals a narrowband barotropic oscillation with period 1.8 days in spectra of velocity. The signal is coherent over at least 55km scales and propagates phase with shallow water on the right (towards the northwest). Velocity ellipses tend to be elongated (crossing contours of f=H) and rotate anticycloni...

Revisiting Queney’s Flow Over a Mesoscale Ridge

The most familiar illustrations of downstream topographic waves are the streamline plots from the original linear wave studies of Queney (1947,1948). For steady flow past a twodimensional ridge, Queney’s downstream radiation patterns were obtained through approximations of the Fourier integral which describes the dispersion of linear gravity waves. In the case of constant stratification with ro...

Laboratory experiments on diapycnal mixing in stratified fluids

Our turbulent lengthscale, velocity and diffusivity scalings are compared with data from other numerical, laboratory and field experiments. Comparison is made with reference to the turbulence intensity measure /νN. We showed that our turbulent lengthscale and velocity results are consistent with measurements from the experiments considered, and that the rms turbulent lengthscale Lt is independe...

Turbulent mixing in a stratified fluid

The strength of diapycnal mixing by small-scale motions in a stratified fluid is investigated through changes to the mean buoyancy profile. We study the mixing in laboratory experiments in which an initially linearly stratified fluid is stirred with a rake of vertical bars. The flow evolution Ž . depends on the Richardson number Ri , defined as the ratio of buoyancy forces to inertial forces. A...
