Modules for simple dynamics, mostly for use in Energy Balance Models.
BudykoTransport is a relaxation to global mean.
Other modules are 1D diffusion solvers (implemented using implicit timestepping).
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.
