Nacreous clouds that form in the lower stratosphere sometimes have lenticular shapes. There are three main types of lenticular clouds: altocumulus standing lenticular (ACSL), stratocumulus standing lenticular (SCSL), and cirrocumulus standing lenticular (CCSL), varying in altitude above the ground.
Clouds of the genus nimbostratus tend to bring constant precipitation and low visibility. This cloud type normally forms above 2 kilometres (6,600 ft) [10] from altostratus cloud but tends to thicken into the lower levels during the occurrence of precipitation. The top of a nimbostratus deck is usually in the middle level of the troposphere.
A pileus (/ ˈ p aɪ l i ə s /; Latin for 'cap'), also called scarf cloud or cap cloud, is a small, horizontal, lenticular cloud appearing above a cumulus or cumulonimbus cloud. Pileus clouds are often short-lived, appearing for typically only a few minutes, [ 1 ] with the main cloud beneath them rising through convection to absorb them.

Lenticular clouds. Northern California photographer Robert Renick took this photo of a lenticular cloud over Mt. Shasta in Northern California during a wet winter on Jan. 22, 2023.
The peculiar cigar-shaped cloud is called an altocumulus standing lenticular cloud (ASLC) and is created when winds encounter a steep barrier such as a mountain range, Nasa explained in a statement.
Lenticular clouds are stationary lens-shaped clouds that are formed downwind of mountains by lee waves if the air mass is close to the dew point. [3] They are normally aligned at right-angles to the wind direction and are formed at altitudes up to 12,000 metres (39,370 ft).
Stratocumulus lenticularis is an uncommon cloud type that belongs to the stratocumulus cloud type, its appearance is that of a flat lens or almond. It forms as a result of atmospheric waves [ 1 ] caused by wind passing over obstacles; for example, a mountain or a building.
