What shape characterizes lenticular clouds?

Lenticular clouds are characterized by a distinct lens shape, which arises when moist air encounters a mountain or a similar geographical obstruction. As the air flows over the top of the obstacle, it is forced upward, leading to cooling and condensation, forming these unique clouds. The lens-like shape of lenticular clouds resembles a saucer or a lens, typically appearing smooth and continuous, which sets them apart from other cloud formations that may have more chaotic or irregular outlines.

The distinctive form of lenticular clouds is a result of their formation process, where air currents create stable wave patterns. When conditions are right, these clouds can develop into dramatic and visually striking formations that often look like UFOs hovering in the sky. This lens shape is essential for identifying lenticular clouds and understanding their meteorological significance.
