! Remarques: |
| 20 |
|
| 21 |
! - Les vents sont donn\'es dans la physique par leurs composantes |
| 22 |
! naturelles. |
| 23 |
|
| 24 |
! - La variable thermodynamique de la physique est une variable |
| 25 |
! intensive : T. |
| 26 |
! Pour la dynamique on prend T * (preff / p)**kappa |
| 27 |
|
| 28 |
! - Les deux seules variables d\'ependant de la g\'eom\'etrie |
| 29 |
! n\'ecessaires pour la physique sont la latitude (pour le |
| 30 |
! rayonnement) et l'aire de la maille (quand on veut int\'egrer une |
| 31 |
! grandeur horizontalement). |
