The photograph shows small detached shreds of Cumulus cloud. It is identified as the species fractus due to the very ragged, fuzzy and indistinct edges at 1 and 2. The cloud shapes and outlines undergo continual changes that can be quite rapid. In the distance, a few Cumulus humilis can be seen at 3 and 4; the edges are more distinct, the bases are horizontal and the cloud is of small vertical extent with a flattened appearance.

Cumulus are detached clouds, generally dense and with sharp outlines, developing vertically in the form of rising mounds, domes or towers, with mostly brilliant white sunlit parts. In this photograph, we see two species of Cumulus. Towards the top of the image (nearer the camera), the cloud has the ragged, irregular edges of Cumulus fractus, the outlines of which usually change quickly and constantly. These are most likely the initial stages of the development of Cumulus. In the distance we note cloud with sharp outlines, of very limited vertical growth and seemingly flattened; this defines Cumulus humilis.

This image shows small detached Cumulus clouds on a breezy day on the coast of Cornwall, UK. The ragged and indistinct edges of the cloud at 1 and 2 identify the species as fractus. When viewed looking away from the Sun, as in this case, fractus has a bright white appearance. The shapes and outlines of fractus undergo continual changes that can be quite rapid.

This photograph shows the initial phase of formation of Cumulus fractus. It is an excellent example of water vapour condensing and almost immediately evaporating. The small water droplets are visible long enough to appear as a nebulous milky sheen at 1 and 2. Two small white spots at 3 and 4 are the first sign that a cloud is forming; it is probably the beginning of Cumulus humilis.

This Cumulus humilis and fractus followed the cessation of daytime convective cloud within the north-east trades region in the Caribbean. Grand Anse Beach, Grenada at 1811 local time on 26 Sept 1978.

The photograph shows small detached shreds of Cumulus cloud trying to form in a post-cold front airstream that remained quite moist. The cloud edges are ragged and diffuse at 1, 2 and 3, identifying the species as fractus. The outline and shape of the Cumulus was constantly changing.

Most of these clouds are typical Cumulus humilis. They have distinct horizontal bases, generally shaded; their outlines are not very ragged, their tops are flattened as a whole and only slightly rounded in places. There are some Cumulus fractus at 1 and 2.
The sky was observed in the western portion of a weak anticyclone which covered Finland and Sweden.
