static

Computes the moving atmospheric pressure disturbance for the Gulf of Mexico test case.

The pressure field is modelled as an asymmetric Gaussian pulse that travels along a great-circle–like path between two geographic points (A,B), defined in lon/lat. The function takes Cartesian model coordinates (x,y) in the Albers Equal-Area projection, maps them back to lon/lat, aligns the (A,B) path with a local x-axis, and evaluates the pressure profile in this rotated coordinate system.

Template Parameters

pointLonA	Longitude of path start point A [deg].
pointLatA	Latitude of path start point A [deg].
pointLonB	Longitude of path end point B [deg].
pointLatB	Latitude of path end point B [deg].

Parameters

x	Cartesian x-coordinate in projected space [m].
y	Cartesian y-coordinate in projected space [m].
t	Physical time [s].
projectionFunctionForward	Callable that maps (lon,lat) → (x,y) in the chosen projection.
projectionFunctionInverse	Callable that maps (x,y) → (lon,lat) in the chosen projection.

Returns

Atmospheric pressure perturbation at (x,y,t) [Pa].
