Altocumulus (from Latin altus 'high' and cumulus 'heaped') [1] is a middle-altitude cloud genus that belongs mainly to the stratocumuliform physical category, characterized by globular masses or rolls in layers or patches – the individual elements being larger and darker than those of cirrocumulus and smaller than those of stratocumulus. [2] …

These elements usually are sharply outlined, but they may become partly fibrous or diffuse; they may or may not be merged; they generally have shadowed parts; and, by convention, when observed at an angle of more than 30° above the horizon, an altocumulus element subtends an angle between 1° and 5°. Small liquid water droplets invariably compose the major part of the composition of altocumulus.

The WMO International Cloud Atlas is the reference for the classification of clouds and meteorological meteors. It provides the definitions and descriptions of cloud types and meteors, and flow charts to help identify them.

White or grey, or both white and grey, patch, sheet or layer of cloud, generally with shading, composed of laminae (a layer or layers), rounded masses, rolls, etc., which are sometimes partly fibrous or diffuse and which may or may not be merged; most of the regularly arranged small elements usually...

Altocumulus and cirrocumulus clouds share many of the same cloud species, but cirrocumulus clouds are higher in altitude, so their cloudlets appear smaller. Cirrocumulus clouds are more often than not seen with cirrus and cirrostratus clouds in near proximity. Altocumulus clouds are also more commonly observed than cirrocumulus.

2019年7月23日 · An altocumulus cloud is a middle-level cloud that lives between 6,500 to 20,00 feet above ground and is made of water. Its name comes from the Latin Altus meaning "high" + Cumulus meaning "heaped."

Altocumulus most frequently occurs at altitudes between 2 km and 4 km (6 500 ft and 13 000 ft) in polar regions, between 2 km and 7 km (6 500 ft and 23 000 ft) in temperate regions and between 2 km and 8 km (6 500 ft and 25 000 ft) in tropical regions.

L'ampiezza di questo fenomeno nuvoloso può estendersi a tutto il cielo visibile oppure a grandi settori di questo, ben delineate e marcate rispetto ad un cielo sereno; in altri casi gli altocumuli si alternano ad altostrati, oppure a fenomeni nuvolosi di altitudine più elevata, quali cirrostrati o veli. Frequentemente l'altocumulo si presenta ...
