Windrows in Global Models. Greg Chini, Eric D'Asaro, Ramsey Harcourt, Keith Julien, Edgar Knobloch, Bill Large, Synte Peacock, Adrean Webb, Erik Stevens, and I are studying the impacts of including a parameterization of Langmuir circulations on climate, including a survey of the forcing of Langmuir circulations from satellite observations. Grants: IRP08, ROSES08, IGP09, CMG09. |

The Past, Present, and Future ENSO. Markus Jochum, Peter Molnar, Samantha Stevenson, Steve Yeager, Christine Shields and I are studying the changes to the El Nino/Southern Oscillation (ENSO) under different climate forcing scenarios, from the early Pliocene to potential future warming scenarios. Grants: NESSF. Papers: JFMS09. |

Diagnosing & Parameterizing Eddy Stirring. In collaboration with a team of scientists using the 1/10 degree global POP model, especially Frank Bryan and John Dennis, I am trying to optimally diagnose eddy tracer transport. If this transport were mapped, it would be a powerful tool in understanding and parameterizing mesoscale eddy fluxes. I have experience in eddy parameterizations, which will help for this project. Grants: PO08, FRG09. Papers: FFP03, FM08, FFH08, FF08, FDFH08, FF09. |

Submesoscale Eddies in the Ocean Mixed Layer. In collaboration with members of the climate process team on eddy-mixed layer interaction, I've been working on modeling and parameterizing submesoscale eddies in the oceanic mixed layer. Presently, I am working with Raf Ferrari and Glenn Flierl on high horizontal-resolution simulations of these submesoscale eddies and their interactions with mesoscale eddies. The model is a limited vertical-mode model based on Blumen's. A new direction (with Chini, Julien, D'Asaro and Harcourt) is the coupling (or lack thereof) between convective plumes and Langmuir turbulence and mixed layer eddies. Grants: FRG09, CMG09. Papers: BFF07, FFH08, FF08, FF09. |

Wind-Driven Ocean. My dissertation work focused on closing the vorticity budget in the wind-driven ocean. That is, if the wind spins up the ocean, how does it spin-down/equilibrate? I wrote a Chebyshev-pseudospectral model for simulating a barotropic ocean at high Reynolds number, and published a number of papers studying this model and using it to interpret the ocean. Balu Nadiga and I are presently trying to understand how and why a Lagrangian-averaged alpha model is able to reproduce some of the high-resolution effects in this model at coarser resolution. Joel Franklin and I have been talking about doing stochastics in this model for years, and might just do it some day... Papers: FP04, F04, F05, FF09. |
