Here's why:
* Orographic Lift: As moist air is forced upward by mountains, it cools. This cooling causes the moisture in the air to condense, forming clouds.
* Stable Air: Lenticular clouds form in stable air. This means the air is not prone to vertical mixing, allowing the cloud to maintain its distinct shape.
* Wave Formation: The rising and sinking air over mountains can create wave patterns in the atmosphere. Lenticular clouds often form at the crest of these waves.
Other factors:
* Wind: Lenticular clouds are most common when winds are strong and consistent.
* Moisture: The presence of enough moisture is necessary for cloud formation.
While they are commonly seen near mountains, lenticular clouds can also form near other topographic features, such as islands or isolated hills, as long as the necessary conditions are met.
