C !LOCAL VARIABLES: |

C === Local variables === |
| 61 |
C |
| 62 |
C unit/sign convention: |
| 63 |
C Within the thermodynamic computation all stocks, except HSNOW, |
| 64 |
C are in 'effective ice meters' units, and >0 implies more ice. |
| 65 |
C This holds for stocks due to ocean and atmosphere heat, |
| 66 |
C at the outset of 'PART 2: determine heat fluxes/stocks' |
| 67 |
C and until 'PART 7: determine ocean model forcing' |
| 68 |
C This strategy minimizes the need for multiplications/divisions |
| 69 |
C by ice fraction, heat capacity, etc. The only conversions that |
| 70 |
C occurs are for the HSNOW (in effective snow meters) and |
| 71 |
C PRECIP (fresh water m/s). |
| 72 |
C |
| 73 |
C HEFF is effective Hice thickness (m3/m2) |
| 74 |
C HSNOW is Heffective snow thickness (m3/m2) |
| 75 |
C HSALT is Heffective salt content (g/m2) |
| 76 |
C AREA is the seaice cover fraction (0<=AREA<=1) |
| 77 |
C Q denotes heat stocks -- converted to ice stocks (m3/m2) early on |
| 78 |
C |
| 79 |
C For all other stocks/increments, such as d_HEFFbyATMonOCN |
| 80 |
C or a_QbyATM_cover, the naming convention is as follows: |
| 81 |
C The prefix 'a_' means available, the prefix 'd_' means delta |
| 82 |
C (i.e. increment), and the prefix 'r_' means residual. |
| 83 |
C The suffix '_cover' denotes a value for the ice covered fraction |
| 84 |
C of the grid cell, whereas '_open' is for the open water fraction. |
| 85 |
C The main part of the name states what ice/snow stock is concerned |
| 86 |
C (e.g. QbyATM or HEFF), and how it is affected (e.g. d_HEFFbyATMonOCN |
| 87 |
C is the increment of HEFF due to the ATMosphere extracting heat from the |
| 88 |
C OCeaN surface, or providing heat to the OCeaN surface). |
