orographic precipitation

[¦ȯr·ə¦graf·ik prə‚sip·ə′tā·shən]
(meteorology)
Precipitation which results from the lifting of moist air over an orographic barrier such as a mountain range; strictly, the amount so designated should not include that part of the precipitation which would be expected from the dynamics of the associated weather disturbance, if the disturbance were over flat terrain.

Through the process known as orographic precipitation, when moist air rises up a mountain and cools to the point of condensation which leads to rain or snow, could explain the creation of valley networks which would appear on one side of a Martian mountain but not on the other side.
