Turbulent convection in the anelastic rotating sphere : a model for the circulation on the giant planets
(Massachusetts Institute of Technology, 2008)
This thesis studies the dynamics of a rotating compressible gas sphere, driven by internal convection, as a model for the dynamics on the giant planets. We develop a new general circulation model for the Jovian atmosphere, ...
Arctic Ocean circulation in an idealized numerical model
(Massachusetts Institute of Technology, 2008)
The mid-to-deep Arctic Ocean is generally characterized by a cyclonic circulation, contained along shelves and ridges. Here we analyze the general Arctic circulation using an idealized numerical model consisting of a ...
On the warm bias along the South-West African Coast in coupled models : an oceanic perspective
(Massachusetts Institute of Technology, 2008)
Coupled ocean/atmosphere simulations exhibit systematic warm biases over the South West African (SWA) coastal region. Recent investigations indicate that coastal ocean dynamics may play an important role in determining the ...
Assessment of mesoscale eddy parameterizations for coarse resolution ocean models
(Massachusetts Institute of Technology, 1999)
Climate simulation with numerical oceanic models requires a proper parameterization scheme in order to represent the effects of unresolved mesoscale eddies. Even though a munber of schemes have been proposed and some have ...
Generation of mid-ocean eddies : the local baroclinic instability hypothesis
(Massachusetts Institute of Technology, 2000)
Strong wind events across Greenland's coast and their influence on the ice sheet, sea ice and ocean
(Massachusetts Institute of Technology, 2012)
In winter, Greenland's coastline adjacent to the subpolar North Atlantic and Nordic Seas is characterized by a large land-sea temperature contrast. Therefore, winds across the coast advect air across a horizontal temperature ...
A 2 1/2 dimensional thermohaline circulation model with boundary mixing
(Massachusetts Institute of Technology, 2000)
A simple quasi-two dimensional dynamical model of Thermohaline circulation (THC) is developed, assuming that the mixing only occurs near western and eastern boundary layers. When the surface density is prescribed, the ...
Shelf currents, ice and wind : a numerical modeling study
(Massachusetts Institute of Technology, 2003)
In this thesis, the effects of sea ice, downwelling favorable winds and barotropic background currents on shelf fronts are examined using numerical models. The models are configured with the characteristics of the East ...
On the role of topography and of boundary forcing in the ocean circulation
(Massachusetts Institute of Technology, 1987)
Eddy-mean flow interactions in western boundary current jets
(Massachusetts Institute of Technology, 2009)
This thesis examines the nature of eddy-mean flow interactions in western boundary current jets and recirculation gyre dynamics from both theoretical and observational perspectives. It includes theoretical studies of ...
