C-- By default, pkg/seaice defines forcing variable internally, in |
| 29 |
|
|
C SEAICE_FFIELDS.h, and reads them in from files. When CPP option |
| 30 |
|
|
C SEAICE_EXTERNAL_FORCING is defined, the above forcing variables |
| 31 |
|
|
C are defined and provided by an external package. At present this |
| 32 |
|
|
C option is hardwired for pkg/exf and the variables are passed using |
| 33 |
|
|
C include file exf_fields.h. |

C-- By default, the sea-ice package uses its own integrated bulk |
| 40 |
|
|
C formulae to compute fluxes (fu, fv, EmPmR, Qnet, and Qsw) over |
| 41 |
|
|
C open-ocean. When this flag is set, these variables are computed |
| 42 |
|
|
C in a separate external package, for example, pkg/exf, and then |
| 43 |
|

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

C-- By default, the sea-ice package uses 2-category thermodynamics. |
| 47 |

C When this flag is set, an 8-category calculation of ice |
| 48 |

C thermodynamics is carried out in groatb.F |

C Note the pickup_seaice.* generated by this option differ |

C Therefore it is not possible to switch between the two |

C-- By default cdm wind stress under sea-ice is set to the |
| 56 |
|
|
C same value as it would be if there was no sea-ice. |
| 57 |
|
|
C This is a placeholder until a more physically-sensible |
| 58 |
|
|
C stable solution is developed. Apparently ocean stress |
| 59 |
|
|
C that is based on sea-ice velocity can cause trouble in |
| 60 |
|
|
C Arctic Ocean configurations. This temporary solution |
| 61 |
|
|
C also corresponds to that adopted by CCSM-2. For the |
| 62 |
