part of has quality has member composed primarily of object aggregate liquid water water droplet altocumulus cloud Ac Altocumulus-Wolke Grobe Schäfchenwolke A cloud which 1) has been shaped into laminae, rounded masses or rolls, 2) is exclusively composed of water droplets, 3) is located in the middle level of the atmosphere (middle étage). Altocumulus clouds are sometimes fibrous or diffuse and may or may not be merged. When present in aggregates, individual altocumulus clouds are organised in patches, sheets or layers. Most of the regularly arranged small elements in this cloud type often have an apparent width of between one and five degrees. When well-illuminated by sunlight (excluding during sunrise and sunset) altocumulus clouds appear white, grey, or both white and grey, often with shading. The composition of altocumulus clouds leads to low transparency and sharp outlines of the elements. Absence of any precipitation. This definition is very odd, it seems to allow for such a wide range of variation that the boundaries of this class become suspect.
