Rhea Orographic Model
For a layer forced up or down by terrain.
-keeps track of condensation
-part of condensate precipitates (based on empirical Precipitation Efficiency Factor)
-the rest moves downstream with the parcel
-Part of imported condensate precipitates along with additional condensate produced by additional orographic lift
-the rest moves downstream with the parcel
-Partial or total evaporation occurs
-if the parcel becomes supersaturated, saturation deficit is computed
-precipitation into a dry layer will partially or totally evaporate
