Short summary
Carbon dioxide (CO2) clouds have been frequently observed in the Martian middle atmosphere. There are still uncertainties concerning the formation of the clouds. Using an atmospheric model for Mars, including a gravity wave parameterization, we assess the role of gravity waves in cloud formation. Simulations suggest that gravity wave processes constitute a necessary physical mechanism for CO2 cloud formation in the Martian upper atmosphere during all seasons.
