c   1. rearrangement des tableaux et transformation
c      variables dynamiques  >  variables physiques
c   2. calcul des termes physiques
c   3. retransformation des tendances physiques en tendances dynamiques
c
c   remarques:
c   ----------
c
c    - les vents sont donnes dans la physique par leurs composantes 
c      naturelles.
c    - la variable thermodynamique de la physique est une variable
c      intensive :   T 
c      pour la dynamique on prend    T * ( preff / p(l) ) **kappa
c    - les deux seules variables dependant de la geometrie necessaires
c      pour la physique sont la latitude pour le rayonnement et 
c      l'aire de la maille quand on veut integrer une grandeur 
c      horizontalement.
c    - les points de la physique sont les points scalaires de la 
c      la dynamique; numerotation:
c          1 pour le pole nord
c          (jjm-1)*iim pour l'interieur du domaine
c          ngridmx pour le pole sud
c      ---> ngridmx=2+(jjm-1)*iim
c
c     Input :
c     -------
c       ecritphy        frequence d'ecriture (en jours)de histphy

c       pvcov           covariant meridional velocity 
c       pteta           potential temperature
c       pps             surface pressure
c       pmasse          masse d'air dans chaque maille
c       pts             surface temperature  (K)

! Introduction du splitting (FH)
! Question pour Yann :
! J'ai été surpris au début que les tableaux zufi_omp, zdufi_omp n'co soitent
! en SAVE. Je crois comprendre que c'est parce que tu voulais qu'il
! soit allocatable (plutot par exemple que de passer une dimension
! dépendant du process en argument des routines) et que, du coup,
! le SAVE évite d'avoir à refaire l'allocation à chaque appel.
! Tu confirmes ?
! J'ai suivi le même principe pour les zdufic_omp
! Mais c'est surement bien que tu controles.
