MOC image of various types of clouds. (Malin Space Science Systems/NASA)	Viking 2 Orbiter image of wave clouds near the south pole of Mars. This complex pattern of clouds is caused by winds passing over the craters. (NASA)	Viking 1 Orbiter near Mars' northern polar cap showing a cyclonic weather system. (NASA)
This Viking 1 Orbiter image shows clouds to the north of Valles Marineris that look similar to cirrus clouds on Earth. (NASA)	This Viking 1 Orbiter image shows a low pressure cell near the north pole of Mars. These clouds are low in the atmosphere and most likely composed of water ice.
