Modeling convection in the Greenland Sea
(Massachusetts Institute of Technology, 1998)
A detailed examination of the development of a deep convection event observed in the Greenland Sea in 1988-89 is carried out through a combination of modeling, scale estimates, and data analysis. We develop a prognostic ...
Vortices in sinusoidal shear, with applications to Jupiter
(Massachusetts Institute of Technology, 2016)
In this thesis, we have studied the existence of vortex steady states in a sinusoidal background shear flow in a 1.75 layer quasi-geostrophic model. Trying to find vortex structures by integrating the Hamiltonian system ...
Linear and nonlinear Rossby waves in basins both with and without a thin meridional barrier
(Massachusetts Institute of Technology, 2002)
The linear and nonlinear Rossby wave solutions are examined in homogeneous square basins on the [beta]-plane both with and without a thin meridional barrier. In the presence of the meridional barrier the basin is almost ...
Variability of zooplankton and sea surface temperature in the Southern Ocean
(Massachusetts Institute of Technology, 2006)
Interactions between physical and biological processes in the Southern Ocean have significant impacts on local ecosystems as well as on global climate. In this thesis, I present evidence that the Southern Ocean circulation ...
Production and analysis of a Southern Ocean state estimate
(Massachusetts Institute of Technology, 2006)
A modern general circulation model of the Southern Ocean with one-sixth of a degree resolution is optimized to the observed ocean in a weighted least squares sense. Convergence toward the state estimate solution is carried ...
Ice shelf-ocean interactions in a general circulation model : melt-rate modulation due to mean flow and tidal currents
(Massachusetts Institute of Technology, 2012)
Interactions between the ocean circulation in sub-ice shelf cavities and the overlying ice shelf have received considerable attention in the context of observed changes in flow speeds of marine ice sheets around Antarctica. ...
Comparison of wind stress algorithms, datasets and oceanic power input
(Massachusetts Institute of Technology, 2009)
If the ocean is in a statistically steady state, energy balance is a strong constraint, suggesting that the energy input into the world ocean is dissipated simultaneously at the same rate. Energy conservation is one of the ...
Winter mixed-layer development in the central Irminger Sea : the effect of strong, intermittent wind events
(Massachusetts Institute of Technology, 2006)
The impact of the Greenland tip jet on the wintertime mixed-layer of the southwest Irminger Sea is investigated using in-situ moored profiler data and a variety of atmospheric data sets. The mixed-layer was observed to ...
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 ...
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 ...
