Last change on this file since 4299 was 1279, checked in by Laurent Fairhead, 15 years ago
Merged LMDZ4-dev branch changes r1241:1278 into the trunk Running trunk and LMDZ4-dev in LMDZOR configuration on local machine (sequential) and SX8 (4-proc) yields identical results (restart and restartphy are identical binarily) Log history from r1241 to r1278 is available by switching to source:LMDZ4/branches/LMDZ4-dev-20091210
Property svn:eol-style set to `native` Property svn:keywords set to `Author Date Id Revision`

40	c 3. retransformation des tendances physiques en tendances dynamiques
41	c
42	c remarques:
43	c ----------
44	c
45	c - les vents sont donnes dans la physique par leurs composantes
46	c naturelles.
47	c - la variable thermodynamique de la physique est une variable
48	c intensive : T
49	c pour la dynamique on prend T * ( preff / p(l) ) **kappa
50	c - les deux seules variables dependant de la geometrie necessaires
51	c pour la physique sont la latitude pour le rayonnement et
52	c l'aire de la maille quand on veut integrer une grandeur
53	c horizontalement.
54	c - les points de la physique sont les points scalaires de la
55	c la dynamique; numerotation:
56	c 1 pour le pole nord
57	c (jjm-1)*iim pour l'interieur du domaine
58	c ngridmx pour le pole sud
59	c ---> ngridmx=2+(jjm-1)*iim

62	c -------
63	c pucov covariant zonal velocity
64	c pvcov covariant meridional velocity
65	c pteta potential temperature
66	c pps surface pressure
67	c pmasse masse d'air dans chaque maille
68	c pts surface temperature (K)
69	c callrad clef d'appel au rayonnement
70	c
71	c Output :
72	c --------
73	c pdufi tendency for the natural zonal velocity (ms-1)
74	c pdvfi tendency for the natural meridional velocity
75	c pdhfi tendency for the potential temperature
76	c pdtsfi tendency for the surface temperature
