The story of the paper could be: |
Recommendations |
| 5 |
B-grid ice model + C-grid ocean model does not work properly for us, |
\begin{itemize} |
| 6 |
therefore C-grid ice model with advantages: |
\item use the LSOR or another implicit solver, because EVP tends to |
| 7 |
\begin{enumerate} |
have too weak ice, and is much slower for the recommended time step |
| 8 |
\item stress coupling simpler (no interpolation required) |
choices ($\frac{1}{120}$ of the model time step). Linearization does |
| 9 |
\item different boundary conditions |
not appear to be an issue for the short time steps used in this |
| 10 |
\item advection schemes carry over trivially from main code |
study ($\Delta{t} = 20\text{\,min}$), and the LSOR-solver converges |
| 11 |
\end{enumerate} |
quickly (only a few iterations) at each time step, because the |
| 12 |
LSR/EVP solutions are similar with appropriate bcs, evp parameters as |
forcing changes only slowly within 20\,min. |
| 13 |
a function of forcing time scale (when does VP solution break |
\item thermodynamics appears to thave the second largest effect (after |
| 14 |
down). Same for LSR solver, provided that it works (o: |
EVP vs.\ LSOR) |
| 15 |
Which scheme is more efficient for the resolution/time stepping |
\item use a flux limited scheme without explicit diffusion for |
| 16 |
parameters that we use here. What about other resolutions? |
advecting thermodynamic variables |
| 17 |
|
\item use no slip boundary conditions, they make more sense |
| 18 |
|
\item TEM has little effect on the solution, other rheologies that |
| 19 |
|
differ more from the elliptic yield curve may have bigger effects |
| 20 |
|
\item the effects of \citet{hibler87}'s stress formulation on both ice |
| 21 |
|
and ocean model need further exploration |
| 22 |
|
\end{itemize} |
