Waves may also form in dry air without cloud markers. [4] Wave clouds do not move downwind as clouds usually do, but remain fixed in position relative to the obstruction that forms them. Around the crest of the wave, adiabatic expansion cooling can form a cloud in shape of a lens (lenticularis). Multiple lenticular clouds can be stacked on top ...
Wind flow over a mountain produces oscillations (A), (B) etc. Mountain waves are formed when four requirements are met. When these factors coincide with jet streams, CAT can occur: A mountain range, not an isolated mountain; Strong perpendicular wind; Wind direction maintained with altitude; Temperature inversion at the top of the mountain range
Two generic types of wave turbulence should be distinguished: statistical wave turbulence (SWT) and discrete wave turbulence (DWT). In SWT theory exact and quasi-resonances are omitted, which allows using some statistical assumptions and describing the wave system by kinetic equations and their stationary solutions – the approach developed by Vladimir E. Zakharov.
Thin scattered wave-cloud resembling cirrocumulus. Low stratocumuliform Wave-cloud resembling stratocumulus, especially as a polar cap cloud over the winter pole which is mostly composed of suspended frozen carbon dioxide. [25] [26] Surface-based Morning fog of water and/or carbon dioxide commonly forms in low areas of the planet.
The Sierra Wave is a type of air current created by winds that lift off the Sierra Nevada mountain range of California. Known as lee waves , Sierra Waves form as winds hit the Sierra Nevada and are forced to rise, causing water vapor to condense as it cools and forming lenticular clouds on the leeward side of the mountain range.
Mountain wave turbulence, as the name suggests, happens when the wind hits a mountain and is forced upward off its blustery path. That's why it's common to hit some bumps when you're flying over ...
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.
A lee trough, also known as a dynamic trough, is "A pressure trough formed on the lee side of a mountain range in situations where the wind is blowing with a substantial component across the mountain ridge; often seen on United States weather maps east of the Rocky Mountains, and sometimes east of the Appalachians, where it is less pronounced."
