Message:

Modification pour éviter de faire des calculs avec un q négatif qui peut entraîner
des calculs de t2m irréalistes (raison du plantage avec ORCHIDEE en mode debug a priori)

---

Modifications to prevent calculations with a negative humidity that would lead to
unrealistic calculations for temperature
