Lifting Due To Topography
produces orographic clouds

When air is confronted by a mountain, it is lifted up and over the mountain, cooling as it rises. If the air cools to its saturation point, the water vapor condenses and a cloud forms.

These types of clouds are called "orographic clouds", which develop in response to lifting forced by the topography the earth.
