A mountain top is sometimes capped by a more or less smooth cloud. This cap cloud is related to lenticularis, but forms directly over the mountaintop as opposed to lenticularis, that may form at middle altitudes above the mountain. A cap cloud is formed when humid air (maybe moistened by the mountain terrain) is forced to flow over the mountain, condensing into a cloud.
