The major component of Mars' atmosphere, carbon dioxide, freezes out as dry ice every winter, forming a huge but very thin polar cap.  But in the opposite hemisphere, that cap is subliming back into the atmosphere, creating a high pressure area above it.  With the changing seasons, the atmosphere "flip-flops" from pole to pole, with great barometric pressure changes and hurricane force winds and dust storms observable from earth.
Would you know my name, if I saw you in heaven?
