A Simple Mixing Scheme for Models that Resolve Breaking Internal Waves

reportActive / Technical Report | Accession Number: ADA531123 | Open PDF

Abstract:

Breaking internal waves in the vicinity of topography can reach heights of over 100 m and are thought to enhance basin-wide energy dissipation and mixing in the ocean. The scales at which these waves are modelled often include the breaking of large waves 10s of meters, but not the turbulence dissipation scales centimeters. Previous approaches to parameterize the turbulence have been to use a universally large viscosity, or to use mixing schemes that rely on Richardson-number criteria.
