Water in the atmosphere can exhibit complex phenomena. In this thesis, we investigate some possible behaviors of atmospheric water in the mid-lattitudes. This is done in a saturated setting using the Precipitating Quasi-geopstrophic (PQG) equations. The main results include the following: the scale dependence of atmospheric water on rainfall, the presence and characteristics of Atmospheric Rivers (AR) in PQG, and also the relation between the meridional water flux and rainfall. These results lead to a better understanding of the PQG model in a single phase and also as a precursor for the full PQG model with phase changes.
