cloudth.F90 @ 4219

Last change on this file since 4219 was 1399, checked in by idelkadi, 14 years ago

Modifications relatives a l'inclusion des nouveaux nuages d'Arnaud Jam

calltherm.F90 : remontee de variables suplementaires.

Passage de ztv, zpspsk, zthla, zthl en argument

fisrtilp.F : le programme de nuages avec appel a cloudth

Ajout des arguments : zqta, fraca, ztv, zpspsk, ztla, ztlh,
iflag_cldcon

physiq.F : appel modifie a calltherm et fisrtilp
thermcell_main.F90 : changement dans les flag_thermals_ed
thermcell_plume.F90 : version modifiee entrainement et detrainement

(on retrouve la precendente pour iflag_thermals_ed=10)
