Resonant excitation of coastal Kelvin waves in the two-layer rotating shallow water model
Resonant excitation of coastal Kelvin waves by free inertia–gravity waves impinging on the coast is studied in the framework of the simplest baroclinic model: two-layer rotating shallow water with an idealized straight coast. It is shown that, with respect to the previous results obtained with the one-layer model, new resonances leading to a possible excitation of Kelvin waves appear. The most ...
متن کاملInertia–gravity waves generated by near balanced flow in 2-layer shallow water turbulence on the β-plane
Using a fine resolution numerical model (40002 × 2 grid-points) of the two-layer shallow-water equations of the mid-latitude β-plane dynamics, it is shown that there is no sudden breakdown of balance in the turbulent enstrophy cascade but a faint and continuous emission of inertia–gravity waves. The wave energy accumulates in the equator-ward region of the domain due to the Coriolis parameter d...
متن کاملbalance and inertia–gravity waves in a two-layer baroclinic model
balance, breakdown of balance, and generation of inertia–gravity waves in vortical flows are fundamental topics of prime importance in geophysical fluid dynamics. this research aims to find the optimum balance relation as well as the rossby-number variation of the spontaneous generation of inertia–gravity waves in a baroclinic, two-layer, boussinesq model on a doubly-periodic f-plane geometry f...
متن کاملTwo-layer shallow water system and its applications
Abstract. The multi-layer shallow water system is derived by depth averaging the incompressible Navier-Stokes equations with the hydrostatic assumption within layers. While the single layer shallow water system is hyperbolic, the two-layer system is conditionally hyperbolic because of the coupling terms between the layers. The eigenstructure of the system cannot be found in closed form and the ...
متن کاملCentral-Upwind Schemes for Two-Layer Shallow Water Equations
We derive a second-order semi-discrete central-upwind scheme for oneand two-dimensional systems of two-layer shallow water equations. We prove that the presented scheme is wellbalanced in the sense that stationary steady-state solutions are exactly preserved by the scheme, and positivity preserving, that is, the depth of each fluid layer is guaranteed to be nonnegative. We also propose a new te...
