1. Bates, Michael. A dynamic, embedded Lagrangian model for ocean climate models.

Degree: Climate Change Research Centre (CCRC), 2011, University of New South Wales

A framework is developed for embedding a Lagrangian sub-model into an ocean climatemodel that has a fixed horizontal Eulerian grid. The embedded Lagrangian model can beused to explicitly represent processes that are at the subgrid scale to the Eulerian. TheLagrangian framework has a number of potential applications. The embedded Lagrangianframework is applied to two different applications in level coordinate ocean climate models,namely open ocean deep convection and gravity driven downslope flows. Both of theseprocesses are subgrid scale in the present generation of global scale level coordinate oceanmodels.To embed the Lagrangian model in order to represent open ocean deep convection andgravity driven downslope flows, it is necessary to develop a strategy to partition the massand momentum of the model into an Eulerian component and a Lagrangian component.The Lagrangian parcels, called “blobs,” can be moved around in three dimensions usinga more appropriate set of dynamics and may also interact with the Eulerian model.The technique is not a parameterisation, but rather a framework in which a multitudeof parameterisations may be implemented. It is thus possible to develop parameterisationswhich are analogous to many existing and schemes. Initially, several existing parameterisa-tions are emulated. Then, two schemes are developed, one which models open ocean deepconvection, and the other (based on a streamtube model) models gravity driven downslopeflows.The framework is also tested in several well known idealised test cases. In the testcase for deep convection, a 100m resolution non-hydrostatic model of a deep convectivepatch is used and it is shown that the use of the Lagrangian blobs improved the fidelityof the simulation of a 2km resolution hydrostatic simulation when compared to the useof convective adjustment. Two test cases are used to examine the performance of thescheme for gravity driven downslope flows. The Lagrangain scheme significantly improvesthe representation of the physics of a plume on a uniform slope and the resultant largescale circulation.
