In addition to the dramatic orographic clouds, Mars exhibited many localized discrete clouds.
However, recent advancements in instrumentation, better understanding of cloud dynamical and microphysical processes, and new and improved numerical modeling capabilities have laid the foundation to evaluate the potential of cloud seeding to enhance orographic precipitation in ways not possible in the past decades (Tessendorf et al.
