Western Boundary Current Separation Sensitivity Studies Using a Quasigeostrophic Ocean Model

Monitoring Ocean-atmosphere Interactions in Western Boundary Current Extensions

Western boundary currents as they extend eastward into the ocean basin (referred to here as WBCEs) are regions of intense air-sea interaction, where the ocean loses heat and moisture to the atmosphere and absorbs carbon dioxide. Air-sea interactions in WBCEs can affect weather and climate both locally and remotely, on time scales of days to decades. Thus significant societal benefit can be achi...

Josephson Current For a Graphene Nanoribbon Using a Lattice Model

A tight binding approach based on the Bogoliubov-de Gennes approach has been used to calculate the DC Josephson current for a lattice model for S-GNR-S junctions , for short junctions with respect to superconducting coherence length. We calculate the phase, length, width and chemical potential dependence at the Josephson junction and discuss the similarities and differences with regard to the t...

A Comparison of Paralle Lization Techniques for a Finite Element Quasigeostrophic Model of Regional Ocean Circulation

A barotropic quasigeostrophic nite element model of regional ocean circulation is implemented on three parallel architectures: a Multiple Instruction Multiple Data (MIMD) vector computer, a Single Instruction Multiple Data (SIMD) Hypercube and a network of workstations connected together using Fiber Distributed Data Interface (FDDI). Speci c computationintensive tasks are identi ed and alternat...

Impact of Wind Forcing, Bottom Topography, and Inertia on Midlatitude Jet Separation in a Quasigeostrophic Model

The persistence of unrealistic Gulf Stream separation in numerical models of the ocean has prompted many theories about possible mechanisms that influence the separation of a western boundary current from the coast. In this paper, the joint effects of (a) coastline orientation, (b) bottom topography, and (c) inertia on the midlatitude jet separation are explored in a wind-driven two-layer quasi...
