	48	c ----------
	49	c
	50	c - les vents sont donnes dans la physique par leurs composantes
	51	c naturelles.
	52	c - la variable thermodynamique de la physique est une variable
	53	c intensive : T
	54	c pour la dynamique on prend T * ( preff / p(l) ) **kappa
	55	c - les deux seules variables dependant de la geometrie necessaires
	56	c pour la physique sont la latitude pour le rayonnement et
	57	c l'aire de la maille quand on veut integrer une grandeur
	58	c horizontalement.
	59	c - les points de la physique sont les points scalaires de la
	60	c la dynamique; numerotation:
	61	c 1 pour le pole nord
	62	c (jjm-1)*iim pour l'interieur du domaine
