Abstract A schematic bidimensional model has been developed to describe an extended stratus formed by warm, moist air in a frontal system. Parcel trajectories are followed through the cloud, and the formation of precipitation is considered on the basis of simple assumptions. To the dynamic description, a chemical module has been coupled, which includes the oxidation of SO2 in aqueous-phase (by H2O2, O2 and radicals scavenged from interstitial air) and that of NO and NO2 in gaseous phase with subsequent dissolution of HNO2 and HNO3. The pH of precipitation is calculated. Sensitivity tests have been run to study the influence of various dynamic, microphysical and chemical parameters, such as cloud base temperature, cloud thickness, vertical velocities, initiation temperature and distribution of precipitation in the cloud, and the initial concentrations of different chemical species.
