| Abstract: | Ultraviolet albedo contrasts in the Venus atmosphere are probably large-scale atmospheric waves propagating slowly with respect to the rapid cloud-top zonal winds. Using a simple theoretical model and profiles of mean wind and thermal structure based on Pioneer Venus data, we find planetary-scale gravity waves with phase velocities matching the speeds of the uv markings. We propose an upward-propagating wave and waves trapped at cloud levels as candidates to explain the observed uv features. |
