Abstract: A Lagrangian model is employed to study the characteristics of a horizontal cross-equatorial flow. The Coriolis force and the mean meridional pressure field assumed here render the dynamics of particle flow across the ...

Abstract: The linear instability of divergent perturbations that evolve on a cos2 mean steady zonal jet embedded in a zonal channel on the ? plane and on a rotating sphere is studied for zonally propagating wavelike perturbations ...

Abstract: The Lagrangian description of cross-equatorial flow under any steady, strictly meridional, pressure gradient forcing is shown to comprise an integrable two-degree-of-freedom Hamiltonian system. The system undergoes a ...

Abstract: The linear instability of a piecewise uniform shear flow is classically formulated for nondivergent perturbations on a 2D barotropic mean flow with linear shear, bounded on both sides by semi-infinite half-planes where the ...

Abstract: A hybrid Lagrangian?Eulerian model for calculating the trajectories of near-surface drifters in the ocean is developed in this study. The model employs climatological, near-surface currents computed from a spline fit of ...
