I would speculate that dry perchlorates in dust clouds soak
up some atmospheric water and dry rain falls to the ground.
In the beginning and end of each day the perchlorate enters
a dew phase and passes from ice to liquid to chrystaline
to liquid and to ice. In summer some water is liberated from
the pole. That would describe a complete water cycle.
