Cloud distribution simulated by a Venus GCM
Abstract
A simple cloud model for a Venus general circulation model (GCM), which includes condensation, evaporation and sedimentation of sulfuric acid cloud particles and condensable gases (H2O and H2SO4 vapors), was constructed. The cloud distribution reproduced in the model is the thickest and thinnest in high- and mid-latitudes, respectively. The mixing ratio of H2O and H2SO4 vapor increase with latitude in the cloud and the sub-cloud levels, which are qualitatively consistent with previous measurements. In low-latitudes, the moderately thick cloud with zonal wavenumber 1 and 2 structures is formed and changes in time significantly. These structures would be associated with atmospheric waves in the cloud layer.
