Lenticular clouds are known for their:

Lenticular clouds are indeed characterized by a lens-shaped structure, typically forming in a stable atmosphere downwind of mountains. This formation occurs when moist air flows over a mountain range and encounters a decrease in pressure around the peak. As the air rises, it cools, and if the conditions are right, it condenses into clouds. The distinctive appearance of lenticular clouds resembles a lens or saucer, which is a result of the airflow patterns around the mountains. They can often look very smooth and solid, creating a striking visual effect. This shape is key to identifying lenticular clouds, setting them apart from other types of cloud formations that may exhibit fluffy or more chaotic characteristics.
