Lenticular clouds have been said to be mistaken for UFOs, because many of them have the shape of a "flying saucer", with a characteristic "lens" or smooth, saucer-like shape. Lenticular clouds generally do not form over low-lying or flat terrain, so many people may have never seen one before and don't know that they can exist.
The list of cloud types groups all genera as high (cirro-, cirrus), middle (alto-), multi-level (nimbo-, cumulo-, cumulus), and low (strato-, stratus). These groupings are determined by the altitude level or levels in the troposphere at which each of the various cloud types is normally found. Small cumulus are commonly
Cirrocumulus lenticularis is a type of cirrocumulus cloud. The name cirrocumulus lenticularis is derived from Latin, meaning "like a lentil". [1] Cirrocumulus lenticularis are smooth clouds that have the appearance of a lens or an almond. They usually form at the crests of atmospheric waves, which would otherwise be invisible.
An Air Force investigation later concluded that what Arnold really saw were disc-shaped wave clouds called lenticular clouds, which are not. Lenticular Clouds Shrouding the Peaks of Mount McKinley ...
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.
The wind flows towards a mountain and produces a first oscillation (A) followed by more waves. The following waves will have lower amplitude because of the natural damping. Lenticular clouds stuck on top of the flow (A) and (B) will appear immobile despite the strong wind. Lenticular clouds. In meteorology, lee waves are atmospheric stationary ...
Type Ic clouds consist of metastable water-rich nitric acid in a solid phase. [8] Type II clouds, which are very rarely observed in the Arctic, have cirriform and lenticular sub-types [9] and consist of water ice only. [4] A stratiform type I PSC (white cloud above the orange tropospheric clouds), showing fine horizontal structures in the veil
See wave cloud. Orographic lift occurs when an air mass is forced from a low elevation to a higher elevation as it moves over rising terrain. [1]: 162 As the air mass gains altitude it quickly cools down adiabatically, which can raise the relative humidity to 100% and create clouds and, under the right conditions, precipitation. [1]: 472
