This scenario models the meteotsunami observed near Clearwater Beach, Florida, on 12 February 2010.
The solver advances the two-dimensional nonlinear shallow-water equations with bathymetry, atmospheric pressure gradients, Manning bottom friction, and Coriolis forcing. Bathymetry is taken from a GEBCO subset over the geographic window \( [-98^\circ,-70^\circ] \times [15^\circ,35^\circ] \) and reprojected to an Albers Equal Area (AEA) Cartesian grid.
The atmospheric forcing is prescribed analytically as an asymmetric crest-trough pressure footprint that is advected with constant speed along a path from \( A = (-85.107^\circ, 30.747^\circ) \) to \( B = (-81.562^\circ, 23.448^\circ) \). Clearwater Beach corresponds to the reference point \( C = (-82.83167^\circ, 27.9783^\circ) \). In the implementation, the pressure field is rotated and evaluated through the forward and inverse AEA projection operators so that the forcing remains consistent with the planar model grid.
