Modules for simple dynamics, mostly for use in Energy Balance Models.
BudykoTransport is a relaxation to global mean.
Other modules are 1D advection-diffusion solvers (implemented using implicit timestepping).
AdvectionDiffusion is a general-purpose 1D
advection-diffusion process. It can be used out-of-the-box for models with
Cartesian grid geometry, but also accepts weighting functions for the
divergence operator on curvilinear grids.
MeridionalAdvectionDiffusion implements the
1D advection-diffusion process on the sphere (flux in the north-south direction).
Subclass MeridionalHeatDiffusion is the appropriate class
for the traditional diffusive EBM, in which transport is parameterized as a
meridional diffusion process down the zonal-mean surface temperature gradient.
MeridionalMoistDiffusion implements the moist EBM,
with transport down an approximate gradient in near-surface moist static energy.
