This commit updates the slab ocean module to a parallelisable dynamic slab ocean module. This is particularly relevant if you want to be able to use oceanic heat transport in parallel mode.
It has the following features:
(a) Computes sea ice creation and evolution.
(b) Snow has thermodynamic properties.
(c) Computes oceanic horizontal transport (diffusion & surface-wind driven Ekman transport).
(d) Can be used in parallel mode.
Required callphys.def flags:
The slab ocean and its dependencies can be activated with the following flags (already added to deftank):
## Ocean options
##
# Model slab-ocean (Main flag for slab ocean)
ok_slab_ocean = .true.
# The following flags can only be set to true if ok_slab_ocean is true
# Ekman transport
slab_ekman = .true.
# Ekman zonal advection
slab_ekman_zonadv = .true.
# Horizontal diffusion (default coef_hdiff=25000., can be changed)
slab_hdiff = .true.
# Slab-ocean timestep (in physics timesteps)
cpl_pas = 1
# Gent-McWilliams? Scheme (can only be true if slab_ekman is true)
slab_gm = .true.
Notes:
In the current state, the model crashes if moistadjustment = .true. Unsure whether this is due to the slab or is an inherent issue with moistadj (under investigation).
