| 11 |
|
| 12 |
! Purpose: |
| 13 |
|
| 14 |
! Calcule la différence d'enthalpie et de masse d'eau entre deux |
| 15 |
! appels et calcule le flux de chaleur et le flux d'eau |
| 16 |
! nécessaires à ces changements. Ces valeurs sont moyennées sur la |
| 17 |
! surface de tout le globe et sont exprimées en W/m2 et |
| 18 |
! kg/s/m2. Outil pour diagnostiquer la conservation de l'énergie |
| 19 |
! et de la masse dans la physique. Suppose que les niveaux de |
| 20 |
! pression entre les couches ne varient pas entre deux appels. |
| 21 |
|
| 22 |
! Plusieurs de ces diagnostics peuvent être faits en parallèle : |
| 23 |
! les bilans sont sauvegardés dans des tableaux indices. On |
| 24 |
! parlera "d'indice de diagnostic". |
