Generally, the C-EVP solutions have highest maximum (export out of the |
| 301 |
|
Artic) and minimum (import into the Artic) fluxes as the drift |
| 302 |
|
velocities are largest in this solution. In the extreme, both B- and |
| 303 |
|
C-grid LSOR solvers have practically no ice transport through the |
| 304 |
|
Nares Strait, which is only a few grid points wide, while the C-EVP |
| 305 |
|
solutions allow up to 500\,km$^3$\,y$^{-1}$ in summer. |
