C-- By default, the sea-ice package uses its own integrated bulk |
| 31 |
|
|
C formulae to compute fluxes (fu, fv, EmPmR, Qnet, and Qsw) over |
| 32 |
|
|
C open-ocean. When this flag is set, these variables are computed |
| 33 |
|
|
C in a separate external package, for example, pkg/exf, and then |

C modified for sea-ice effects by pkg/seaice. |

C-- By default, the sea-ice package uses 2-category thermodynamics. |

|
|
C When this flag is set, an 8-category calculation of ice |
| 39 |
|
|
C thermodynamics is carried out in groatb.F |

C from those generated with the default 2-category model. |

C-- By default cdm wind stress under sea-ice is set to the |
| 61 |
|
|
C same value as it would be if there was no sea-ice. |
| 62 |
|
|
C This is a placeholder until a more physically-sensible |
| 63 |
|
|
C stable solution is developed. Apparently ocean stress |
| 64 |
|
|
C that is based on sea-ice velocity can cause trouble in |
| 65 |
|
|
C Arctic Ocean configurations. This temporary solution |
| 66 |
|
|
C also corresponds to that adopted by CCSM-2. For the |
| 67 |

C-- By default the seaice model is discretized on a B-Grid (for |
| 73 |

C historical reasons). Define the following flag to use a new |
