Water vapour is an important greenhouse gas whose distribution has a strong impact on climate. We study the dynamics of atmospheric moisture using an advection-condensation model. The transport of moist parcels is modelled as a large-scale circulating motion with small-scale Brownian fluctuation. Condensation of moisture occurs when the specific humidity of a parcel exceeds a prescribed local saturation value. We consider both the initial-value and the steady-state problem of this stochastic model and derive the probability distribution of the moisture field. Theoretical predictions are verified by Monte Carlo simulations.
