45	! 2. calcul des termes physiques
46	! 3. retransformation des tendances physiques en tendances dynamiques
47	!
48	! remarques:
49	! ----------
50	!
51	! - les vents sont donnes dans la physique par leurs composantes
52	! naturelles.
53	! - la variable thermodynamique de la physique est une variable
54	! intensive : T
55	! pour la dynamique on prend T * ( preff / p(l) ) **kappa
56	! - les deux seules variables dependant de la geometrie necessaires
57	! pour la physique sont la latitude pour le rayonnement et
58	! l'aire de la maille quand on veut integrer une grandeur
59	! horizontalement.
60	! - les points de la physique sont les points scalaires de la
61	! la dynamique; numerotation:
62	! 1 pour le pole nord
63	! (jjm-1)*iim pour l'interieur du domaine
64	! ngridmx pour le pole sud
65	! ---> ngridmx=2+(jjm-1)*iim
66	!
67	! Input :
68	! -------
69	! pucov covariant zonal velocity
70	! pvcov covariant meridional velocity
71	! pteta potential temperature
72	! pps surface pressure
73	! pmasse masse d'air dans chaque maille
74	! pts surface temperature (K)
75	! callrad clef d'appel au rayonnement
76	!
77	! Output :
78	! --------
79	! pdufi tendency for the natural zonal velocity (ms-1)
80	! pdvfi tendency for the natural meridional velocity
81	! pdhfi tendency for the potential temperature
