Baroclinic Turbulence in the Ocean: Analysis with Primitive Equation and Quasigeostrophic Simulations
This paper examines the factors determining the distribution, length scale, magnitude, and structure of mesoscale oceanic eddies in an eddy-resolving primitive equation simulation of the Southern Ocean [Modeling Eddies in the Southern Ocean (MESO)]. In particular, the authors investigate the hypothesis that the primary source of mesoscale eddies is baroclinic instability acting locally on the m...
متن کاملCovariate-based stochastic parameterization of baroclinic ocean eddies
Abstract: In this study we investigate a covariate-based stochastic approach to parameterize unresolved turbulent processes within a standard model of the idealised, wind-driven ocean circulation. We focus on vertical instead of horizontal coarse-graining, such that we avoid the subtle difficulties of horizontal coarsegraining. The corresponding eddy forcing is uniquely defined and has a clear ...
متن کاملLagrangian Data Assimilation in Multilayer Primitive Equation Ocean Models
Because of the increases in the realism of OGCMs and in the coverage of Lagrangian datasets in most of the world’s oceans, assimilation of Lagrangian data in OGCMs emerges as a natural avenue to improve ocean state forecast with many potential practical applications, such as environmental pollutant transport, biological, and naval-related problems. In this study, a Lagrangian data assimilation ...
متن کاملParameterization of mixed layer eddies. III: Implementation and impact in global ocean climate simulations
A parameterization for the restratification by finite-amplitude, submesoscale, mixed layer eddies, formulated as an overturning streamfunction, has been recently proposed to approximate eddy fluxes of density and other tracers. Here, the technicalities of implementing the parameterization in the coarseresolution ocean component of global climate models are made explicit, and the primary impacts...
متن کاملAssimilation of drifter observations in primitive equation models of midlatitude ocean circulation
[1] Motivated by increases in the realism of OGCMs and the number of drifting buoys in the ocean observing system, a new Lagrangian assimilation technique is implemented in an idealized, reduced-gravity configuration of the layered primitive equation model MICOM. Using an extensive set of twin experiments, the effectiveness of the Lagrangian observation operator and of a dynamical balancing tec...
