    Barotropic coastal trapped wave modes with complex frequency: edge, shelf and Kelvin waves
    (Woods Hole Oceanographic Institution, 2020-08-01) Brink, Kenneth H.
    This set of Matlab mfiles (all with names beginning with “bwavesc”) can be used to calculate barotropic coastal wave properties in the absence of density stratification. The wave frequency is complex so that unstable or strongly damped modes can be treated. You are allowed to have a mean alongshore flow, if desired, and you can apply the rigid lid approximation. The model can be run in the non-rotating limit if desired. Once a wave’s frequency is found, the modal structure is displayed. The code can use an exact open boundary condition or a closed condition at either side of the domain.

    Coastal-trapped waves with stratification, topography, mean flow and bottom friction with complex frequency in Matlab
    ( 2018-08-17) Brink, Kenneth H.
    This set of Matlab mfiles (all having names that begin with “bigc”) can be used to calculate coastal-trapped wave modal structures and dispersion curves under very general circumstances. A complex frequency is allowed, so that instability and damping can be accounted for directly. Modal structures and energy diagnostics are provided. For most applications, the code is only useful for subinertial wave frequencies (i.e., the real part of wave frequency is smaller than the Coriolis parameter).

    Island-trapped waves with stratification, topography, mean flow and bottom friction in Matlab
    ( 2018-08-17) Brink, Kenneth H.
    This set of Matlab mfiles (all having names that begin with “bigi”) can be used to calculate island-trapped wave modal structures and dispersion curves under very general circumstances for a circular island. A complex frequency is allowed, so that instability and damping can be accounted for directly. Modal structures and energy diagnostics are provided. For most applications, the code is only useful for subinertial wave frequencies (i.e., the real part of wave frequency is smaller than the Coriolis parameter). For interpreting the model results, see Brink (1999), which deals with the case with no mean flow or finite bottom friction. The present code was developed independently of the Fortran code used in that publication.

    Seamount- or Lake/Basin-trapped waves with stratification, topography, mean flow and bottom friction in Matlab
    ( 2018-08-17) Brink, Kenneth H.
    This set of Matlab mfiles (all having names that begin with “bigs”) can be used to calculate seamount-trapped (or basin-trapped) wave modal structures and dispersion curves under very general circumstances. A complex frequency is allowed, so that instability and damping can be accounted for directly. Modal structures and energy diagnostics are provided. For most applications, the code is only useful for subinertial wave frequencies (i.e., the real part of wave frequency is smaller than the Coriolis parameter).

    Stable barotropic coastal trapped wave modes: edge, shelf and Kelvin waves
    (Woods Hole Oceanographic Institution, 2020-08-01) Brink, Kenneth H.
    This set of Matlab mfiles (all with names beginning with “bwavesp”) can be used to calculate barotropic coastal wave properties in the absence of density stratification. The wave frequency is taken to be entirely real (hence stable). You are allowed to have a mean alongshore flow, if desired, and you can apply the rigid lid and/or coastal long wave approximations. The model can be run in the non-rotating limit if desired. Once a wave’s frequency is found, the modal structure is displayed, and a perturbation (weak friction) imaginary correction to the wave frequency is found. The code can use an exact open boundary condition or a closed condition at either side of the domain.

    Stable coastal-trapped waves with stratification, topography and mean flow
    ( 2018-08-17) Brink, Kenneth H.
    This set of Matlab mfiles (all having names that begin with “bigr”) can be used to calculate stable, inviscid coastal-trapped wave modal structures and dispersion curves under very general circumstances. Only a real frequency is allowed, so that instability and damping cannot be accounted for directly, but computations are more efficient than for the general case, long-wave parameters can be computed for first order wave equation calculations (see Brink, 1989), and a more general perturbation decay time (Brink, 1990) can also be obtained. Modal structures and energy diagnostics are provided. Generally speaking, the code is only useful for subinertial wave frequencies.
