Validation of Vertical Mixing in an Equatorial Ocean Model Using Large Eddy Simulations and Observations
Vertical Mixing Equatorial Ocean Model Eddy Simulations
2008/7/8
A nonlocal K-profile parameterization (KPP) of the upper-ocean boundary layer is tested for the equatorial regions. First, the short-term performance of a one-dimensional model with KPP is found to co...
The Effects of Subgrid-Scale Parameterizations in a Zonally Averaged Ocean Model
Subgrid-Scale Parameterizations Zonally Averaged Ocean Model
2008/7/3
Isopycnal diffusion and an additional transport velocity parameterizing the effect of mesoscale eddies are implemented in the ocean component of a 2.5-dimensional zonally averaged coupled ocean–atmosp...
Assimilation of Surface Current Measurements in a Coastal Ocean Model
Assimilation Surface Current Measurements Coastal Ocean Model
2008/7/3
An idealized, linear model of the coastal ocean is used to assess the domain of influence of surface type data, in particular how much information such data contain about the ocean state at depth and ...
Decadal Variability in a Simplified Wind-Driven Ocean Model
Decadal Variability Simplified Wind-Driven Ocean Model
2008/7/2
The impact of an unsteady wind forcing on oceanic low-frequency variability is conceptually studied using a reduced-gravity shallow-water model. A time-averaged wind forcing and a simple ocean–atmosph...
Diagnoses of an Eddy-Resolving Atlantic Ocean Model Simulation in the Vicinity of the Gulf Stream. Part II: Eddy Potential Enstrophy and Eddy Potential Vorticity Fluxes
Eddy-Resolving Atlantic Ocean Gulf Stream Eddy Potential Vorticity Fluxes
2008/6/9
Output of an eddy-resolving model of the North Atlantic is diagnosed in the vicinity of the Gulf Stream (GS), using quasigeostrophic potential vorticity (QGPV), quasigeostrophic potential enstrophy (Q...
Spurious Diapycnal Mixing of the Deep Waters in an Eddy-Permitting Global Ocean Model
Spurious Diapycnal Mixing Deep Waters an Eddy-Permitting Global Ocean Model
2008/6/6
Recent idealized studies have shown that both explicit horizontal diffusion and the implicit diffusion associated with the advection scheme in high-resolution z-coordinate models may drive unrealistic...
On the Role of Sea Ice and Convection in a Global Ocean Model
Role of Sea Ice Convection Global Ocean Model
2008/6/6
An earlier estimate regarding the possible impact of sea ice on deep-ocean water mass properties and the global thermohaline circulation in a coupled sea ice–ocean general circulation model (OGCM) is ...
Effects of Bottom Boundary Layer Parameterization on Reproducing Deep and Bottom Waters in a World Ocean Model
Bottom Boundary Layer Parameterization Reproducing Deep Bottom Waters World Ocean Model
2008/6/6
A simple bottom boundary layer (BBL) model is developed to be incorporated into a z-coordinate medium resolution ocean general circulation model. In the BBL model, velocity is calculated from the pres...
An equatorial ocean model with the Kelvin and first six Rossby waves and n vertical modes is developed to simulate the equatorial sea surface temperature anomalies (SSTAs) and, more importantly, zonal...
The Australian Community Ocean Model (AusCOM) is an initiative by the Australian climate sciences community (including government and academic research laboratories) towards a unified coupled ocean-se...
Reconciling surface ocean productivity,export fluxes and sediment composition in a global biogeochemical ocean model
surface ocean productivity export fluxes sediment composition biogeochemical ocean model
2010/1/13
This study focuses on an improved representation of the biological soft tissue pump in the global three-dimensional biogeochemical ocean model PISCES. We compare three parameterizations of particle dy...
