Windrows in Global Models. The group has been working with many collaborators to study the impacts of wave-driven (Langmuir) mixing of the ocean surface boundary layer on climate. To date, this project has included a surveys of Langmuir forcing from satellite observations and wave models, coupling the NOAA WaveWatch-III model into the NCAR Community Earth System Model, doing theory and Large Eddy Simulations of the wave-Langmuir and wave-submesoscale interactions, and improving parameterizations of Langmuir turbulence for use in global climate models (particularly in non-equilibrium wind-wave conditions). Review paper: CFH12, Grants: IRP08, ROSES08, IGP09, CMG09, NSF13. Papers: WF11, VRF12, CFH12, BG12, MF13, DT14.

The Past, Present, and Future of Climate Variability. With collaborators, our group has been 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: NESSF09, IRP10. Papers: JFMS09, SFJRY10, SFJNDM12, PNFFR12, SFJ12, SMPF13.

Stochastic Models of Climate Variability With collaborators, we are studying nonequilibrium thermodynamics as a possible root cause of climate variability and whether this conceptual approach sheds any light into the quantitative aspects of climate variability and its sensitivity to forcing. Grants: WFKZ13. Papers: SBF13.

Diagnosing & Parameterizing Eddy Stirring. With collaborators, our group is trying to optimally diagnose and parameterize ocean mesoscale eddy tracer transport. So far, we have mapped these eddy transports in a 1/10 degree global ocean simulation using POP and the MITgcm. Work on implementing eddy parameterizations in both of these models and others is underway. Grants: PO08, FRG09, CAREER14. Papers: FFP03, FM08, FFH08, FF08, FF09, GJF11, FLB13, BF13. The datasets for global 0.1degree eddy-induced diffusivities and streamfunctions and grid descriptions from FLB13 are available through the preceding links.

Submesoscale Physics in the Ocean Mixed Layer. With collaborators, our group has been working on modeling and parameterizing submesoscale eddies and other submesoscale dynamics in the oceanic mixed layer. New work centers on the coupling between convective plumes, Langmuir turbulence, Stokes Coriolis and vortex forces, and mixed layer eddies, fronts, and filaments. Grants: FRG09, CMG09. Papers: BFF07, FFH08, FF08, FDFH08, FF09, Fetal.11, Hetal.12.

Wind-Driven Ocean. Baylor's 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? Papers: FP04, F04, F05, FF09, GJF11.

Ocean Climate Modeling Advances. In collaboration with model development centers, our group works to improve the physical underpinnings of the ocean components of global climate models. This work is the primarily application of the basic research detailed above. Grants: All. Papers: Aetal.04, FFH08, FF08, FDFH08, FM08, JFMS09, SFJRY10, Getal.10, Setal.10, Fetal.11, GJF11, BFJLSY12, FLB13, BF13, SMPF13.
