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] .

The altocumulus undulatus is a mid-level cloud (about 8,000–20,000 ft or 2,400–6,100 m), usually white or grey with layers or patches containing undulations that resemble "waves" or "ripples" in water.

Dec 20, 2024 · Altocumulus clouds are mid-level clouds that appear as patches, clumps, or layers of small, rounded formations in various shapes and colors between 6,561 (2,000 meters) and 22,966 (7,000 meters) feet above Earth’s surface.

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.

Rather than a layer of cloudlets, this Altocumulus is in the form of large, smooth individual clouds. Altocumulus clouds produce the most dramatic and beautiful cloudscapes, especially in the rays of a low sun.

Altocumulus lenticularis are lens shaped wave clouds which form in areas of undulating air movement. Where the air is rising and cooling, when the dew point is reached, the cloud develops. Where the air is falling and warming, the cloud evaporates, usually leaving a clear area.

Jul 25, 2023 · Welcome to the captivating world of Altocumulus clouds, where the sky becomes a canvas painted with fluffy, white or gray globules. Prepare to uncover the secrets of how Altocumulus clouds...

Altocumulus clouds are composed primarily of water droplets and are located between 6,500 and 20,000 feet (2,000 to 6,000 meters) above the ground. Altocumulus may appear as parallel bands (top photograph) or rounded masses (bottom photograph).

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.
