Lenticular Clouds are lens-shaped clouds, and are usually formed at a very high altitude. These clouds can be divided into three categories: altocumulus standing lenticular (ACSL), cirrocumulus standing lenticular (CCSL), and stratocumulus standing lenticular (SCSL). These clouds are usually formed perpendicular to the direction of the wind. The lens shape of the cloud is often mistaken by people as a ‘UFO’ or unidentified flying object.
