Moisture Forecast EquationTime changes in moisture are related to Horizontal advection of moisture Vertical advection of moisture Evaporation of liquid water or sublimation of ice crystals Condensation (precipitation). Models have many complicatedformulations for estimating condensation and subsequent precipitation.Note that conservation of moisture means that precipitation predictedby the model reduces the amount of moisture in the model atmosphere.Thus, when a model incorrectly forecasts precipitation, the amount ofmoisture downstream is affectedNote the importance of the vertical velocity determined from the windforecast and continuity equations. There is also interdependencybetween the forecast temperature equation and the amount ofevaporation that can be expected from the earth's surface.
