Cumulus fractus
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.

At 1200 UTC, low pressure of 998 hPa was centred near Shetland, Scotland, UK with an anticyclone of 1 032 hPa west of Ireland. Anticyclonic curvature in the isobars over south-west England resulted in brisk northerly winds at the location of the photograph.

The nearby Camborne, England, UK (WMO 03808) sounding from 1200 UTC shows a very sharp temperature inversion of 4 °C at 900 hPa/1 100 m. The inversion, due to anticyclonic subsidence, helped to limit any cloud development to the unstable boundary layer.

The 1304 UTC satellite image, taken close to the time of the photograph, shows a cold front over northern France. The post-cold front air stream over south-west England, UK appears nearly clear, the resolution not being sufficient to reveal the presence of small amounts of Cumulus fractus.

Cumulus fractus
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.
