Gravity Current Entrainment Climate Process Team
The GCE-CPT is a multi-institutional group of scientists comprised of observationalists, experimentalists, process modelers and climate centers who are working towards improving the representation of gravity current entrainment in climate models.
I am currently working at GFDL and Princeton University as part of the GCE-CPT studying shear-driven mixing and entrainment in overflows. My main focus has been developing a new parameterisation for shear-driven turbulent mixing which is suitable for use in a climate model. This has involved consulting with climate modellers and other scientists, and by studying existing literature and observational data. I conducted high resolution numerical simulations of shear-driven turbulent mixing (using MITgcm) for comparison with theories, and developed a parameterisation which is suitable for climate simulations in that it is robust and efficient, as well as being based on physical principles. I have helped to implement this in one of GFDL's ocean climate models (GOLD, formerly HIM) and have been studying its effects in coupled climate models.
Recently I have also been examining how the presence of a barotropic tide affects the mixing in the Mediterranean overflow.
The role of topography in the ocean general circulation.
I completed my PhD in Physical Oceanography at Liverpool University in 2004. My thesis involved studying flow over idealised topography to understand how large-scale ocean currents, such as the Antarctic Circumpolar Current and the Gulf Stream, are controlled by topographical features, and how the presence of these features affects momentum and vorticity balances.
