This reminds me of when I heard the phrase "lenticular cloud". I looked it up, hoping to learn something about how these clouds are formed, etc. It simply means "shaped like a lentil".
Perhaps this is autocorrect gone awry, but it has nothing to do with lentils.
Not a meteorologist, but from all I understand it means lens-shaped, and to me that immediately gives a strong clue as to how they form since lenses have focal points and can, to some degree, have shapes expressed as formulae about some origin. Which to me is suggestive of the relation to the mountains around which they form.
