Composition and mechanisms of accumulation of ices over the Martian polar caps through analysis of PFS/MEX observations

The composition and the mechanisms of accumulation of ices over the Martian polar caps have been studied through the analysis of PFS/MEX observations. Circulation in the polar night is a result of complex dynamical processes, such as transient eddies and quasi-stazionary planetary waves, which force two distinct regional climates over the south polar region. New insights in the explanation of the South Residual Polar Cap asymmetry, a major Martian curiosity from many years, have been finally provided.
