    ! 1. R\'earrangement des tableaux et transformation des variables
    ! dynamiques en variables physiques

    ! 2. Calcul des termes physiques
    ! 3. Retransformation des tendances physiques en tendances dynamiques

    ! Remarques:

    ! - Les vents sont donn\'es dans la physique par leurs composantes 
    ! naturelles.

    ! - La variable thermodynamique de la physique est une variable
    ! intensive : T.
    ! Pour la dynamique on prend T * (preff / p(l))**kappa

    ! - Les deux seules variables d\'ependant de la g\'eom\'etrie
    ! n\'ecessaires pour la physique sont la latitude (pour le
    ! rayonnement) et l'aire de la maille (quand on veut int\'egrer une
    ! grandeur horizontalement).
