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.

2082! parameterization of ice for boundary
2083! layer mixed-phase clouds assuming a stationary system
2084!
2085! Note that vapor deposition on ice crystals and riming of liquid droplets
2086! depend on the ice number concentration Ni
2087! One could assume that Ni depends on qi, e.g.,  Ni=beta*(qi*rho)**xi
2088! and use values from Hong et al. 2004, MWR for instance
2089! One may also estimate Ni as a function of T, as in Meyers 1922 or Fletcher 1962
2090! One could also think of a more complex expression of Ni;
2091! function of qi, T, the concentration in aerosols or INP ..
2092! Here we prefer fixing Ni to a tuning parameter
2093! By default we take 2.0L-1=2.0e3m-3, median value from measured vertical profiles near Svalbard
2094! in Mioche et al. 2017
