multimodemodel.linearised_SWE

multimodemodel.linearised_SWE(state, params)

Compute RHS of the linearised shallow water equations.

The equations are evaluated on a C-grid. Output is a state object forming the right-hand-side needed for any time stepping scheme. These terms are evaluated:

• pressure_gradient_i()

• pressure_gradient_j()

• coriolis_i()

• coriolis_j()

• divergence_i()

• divergence_j()

Parameters:

• state (State) – Present state of the system.

• params (Parameters) – Parameters of the system.

Returns:

State – Contains the sum of all tendency terms for all prognostic variables.
