That wave cloud pattern formed over the Île Amsterdam, in the lower left corner at the tip of the triangular formation, in the far southern Indian Ocean. A wave cloud is a cloud form created by atmospheric internal waves. Wave cloud pattern in Tadrart region. Unusual wave clouds over the Aral Sea, seen from NASA's Water satellite on March 12 ...
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.
A cap cloud is a special form of the lenticular cloud with a base low enough that it forms around and covers the peak, capping it. [3] A chinook arch cloud is an extensive wave cloud. It has this special name in North America where it is associated with the Chinook wind. It forms above the mountain range, usually at the beginning of a chinook ...
Another highly disturbed but more chaotic wave-like cloud feature associated with stratocumulus or altocumulus cloud has been given the Latin name asperitas. The supplementary feature cavum is a circular fall-streak hole that occasionally forms in a thin layer of supercooled altocumulus or cirrocumulus. Fall streaks consisting of virga or wisps ...
The wavy strips of clouds are generally near an inversion surface. Also referred to as billow clouds , wind row clouds , or wave clouds , variations of the undulatus can be elements that have merged or single elements that have stretched through the sky.
Atmospheric internal waves can be visualized by wave clouds: at the wave crests air rises and cools in the relatively lower pressure, which can result in water vapor condensation if the relative humidity is close to 100%. Clouds that reveal internal waves launched by flow over hills are called lenticular clouds because of their lens-like ...
The cloud quickly dissipates over land where the air is drier. [3] The cloud can also be described as a solitary wave or a soliton or an undular bore, which is a wave that has a single crest and moves without changing speed or shape. They have been called "the biggest waves on the planet". [6] The wave may occur without the appearance of any ...
Rotor clouds have ragged leeward edges and are dangerously turbulent. [4] A foehn wall cloud may exist at the lee side of the mountains, however this is not a reliable indication of the presence of lee waves. A pileus or cap cloud, similar to a lenticular cloud, may form above the mountain or cumulus cloud generating the wave.
