Lenticular clouds over Mt Cook in New Zealand in late February (summer time). Lenticular clouds are often wonderful and interesting to look at. They are sharply defined due to the motion of the air that is rushing through them. Usually forming over or near mountain peaks they are caused by wavelike undulations in the air that is moving over the ground. As the air is forced to rise it cools and its relative humidity increases. If it increases to the saturation point the vapour can condense and form a cloud. But remember, the air is rushing through the cloud at all times.
