tracer_2d_1l

TracerAdvection

Performs horizontal advection on tracers.

Corresponds to tracer_2D_1L in the Fortran code.

__call__(tracers, dp1, x_mass_flux, y_mass_flux, x_courant, y_courant)

Apply advection to tracers based on the given courant numbers and mass fluxes.

Note only output values for tracers are used, all other inouts are only such because they are modified for intermediate computation.

Parameters:

Name	Type	Description	Default
tracers	inout	tracers to advect according to fluxes during acoustic substeps	required
dp1	in	pressure thickness of atmospheric layers before acoustic substeps	required
x_mass_flux	inout	total mass flux in x-direction over acoustic substeps	required
y_mass_flux	inout	total mass flux in y-direction over acoustic substeps	required
x_courant	inout	accumulated courant number in x-direction	required
y_courant	inout	accumulated courant number in y-direction	required

apply_mass_flux(dp1, x_mass_flux, y_mass_flux, rarea, dp2)

Parameters:

Name	Type	Description	Default
dp1	in	initial pressure thickness	required
mfx	in	flux of (area * mass * g) in x-direction	required
mfy	in	flux of (area * mass * g) in y-direction	required
rarea	in	1 / area	required
dp2	out	final pressure thickness	required

divide_fluxes_by_n_substeps(cxd, xfx, mfxd, cyd, yfx, mfyd, n_split)
