An Adjoint Method for Obtaining the Most Rapidly Growing Perturbation to Oceanic Flows
oceanic flows quasigeostrophic model Most Rapidly Growing Perturbation
2008/12/22
This work explores the formation and growth of waves on oceanic flows using a quasigeostrophic model. In particular, we consider flow regimes consisting of zonal oceanic jets, similar in fact to the w...
Rapid Perturbation Growth on Spatially and Temporally Varying Oceanic Flows Determined Using an Adjoint Method：Application to the Gulf Stream
Rapid Perturbation Growth Temporally Varying Oceanic Flows Gulf Stream
2008/12/19
The stability of the Gulf Stream flow predicted by a nonlinear quasigeostrophic model is examined by employing an iterative method, which uses both the tangent linear equations and the adjoint tangent...
The Effect of Current-Induced Stress Perturbation On Baroclinic Rossby Waves in a Continuously Stratified Model
Current-Induced Stress Perturbation Baroclinic Rossby Waves Continuously Stratified Model
2008/12/11
A shear stress at the air–sea interface is induced by the presence of surface currents. In the case of isotropic wind, a quadratic stress law leads to a stress curl proportional to and opposing the su...
