lmdz_cloudth.F90 @ 5260

Last change on this file since 5260 was 5208, checked in by Laurent Fairhead, 2 months ago

Louis d'Alencon modifications:
Il s'agit des modifs permettant de choisir de calculer la variance dans les thermiques par le nouveau modèle (iflag_ratqs = 10) ou de
continuer à calculer cette variance par la param d'Arnaud ce qui fait une version hybride avec variance pronostique dans l'environnement mais
variance diagnostique dans les thermiques (iflag_ratqs = 11). Le iflag_ratqs = 4 version standard continue de faire toutes les variances de façon
diagnostique.
