Propagation of internal wave packets in the thermocline
نویسندگان
چکیده
Internal wave packets propagating vertically in the oceanic thermocline are investigated with numerical simulations. For a typical set of environmental and packet parameters, it is shown that linear dispersion will have a significant effect on the spreading and decay in amplitude of these packets. Sufficiently strong packets are shown to generate turbulence that forms a continuous ‘scar’ of small-scale perturbations in their wake.

Simulations of internal-wave breaking and wave-packet propagation in the thermocline
An investigation into density and velocity fluctuations in the oceanic thermocline is presented. Two kinds of numerical simulation are reported. In the first, an attempt is made to capture the transition from breaking internal waves to the small-scale turbulence they generate. The model used for this is based on a continual forcing of a large-scale standing internal-wave. Evidence is presented ...
متن کاملObservations of internal wave packets propagating along‐shelf in northern Monterey Bay
[1] Internal waves of depression were observed propagating along‐shelf and into northern Monterey Bay, California (CA) on the inner shelf. These waves had amplitudes approximately equal to the thermocline depth (∼4 m), and were unstable to shear and mix the thermocline. Isopycnal gradient spectra showed that the wave packets lead to an elevated mean dissipation rate of " = 2.63 × 10 m s for up ...
