| Description | Numerical models suggest that the impact of kilometre-scale (in the horizontal) eddies may be to increase the depth of the ocean surface mixed layer as well as decrease it. Both baroclinic and symmetric instabilities are responsible for generating these eddies. Observations show a strong seasonal cycle in the vigour of this kilometre-scale turbulence. A new parameterization of vertical mixing in the surface ocean mixed-layer that takes specific account of the interaction between waves and wind gives realistic simulations of the annual cycle of mixed layer depth. |
| Exploitation Route | The new parameterization of vertical mixing in the surface ocean mixed-layer can be implemented into global ocean and then coupled climate models, where it will give better representation of the ocean and may give us a more accurate prediction of the Earth's response to increasing atmospheric C02. |
