Cumulonimbus capillatus incus
The image shows a winter sky of air mass showers falling from a Cumulonimbus capillatus incus. In this example. the Cumulonimbus has almost entirely frozen, as evidenced by the fibrous structure extending almost to the base of the cloud. The cirriform fibrous upper part of this cloud cannot be identified as Cirrus spissatus cumulonimbogenitus as it still attached to the mother-cloud Cumulonimbus.
A Cumulonimbus capillatus cell can be seen in the left distance as well.
Patches of Stratocumulus formed from the spreading of parts of Cumulonimbus are also present.

The photo was taken in the south-westerly flow of a humid maritime modified polar air mass and at the south-eastern flank of a deep, wide and mature extratropical cyclone, 200 km to the rear of the occluded front.© Crown Copyright
The sounding, taken one hour earlier and 100 km north-west of the image location, indicates that the fibrous tops of Cumulonimbus can reach a level of approximately 6 000 m.

The cloud image was taken at the centre of the radar composite, a region where showers were arranged into lines along the prevailing south-westerly wind.© Finnish Meteorological Institute
The NOAA-18 image (a combination of channels 3, 4 and 5), taken 40 minutes before the cloud picture, reveals a small cluster of Cumulonimbus clouds in the middle of the image. The cloud in the later photo is part of the same cluster.

Cumulonimbus capillatus praecipitatio incus mamma praecipitatio
This photo shows a Cumulonimbus capillatus cell with a well-developed symmetrical anvil (supplementary feature incus). The under surface of the incus shows mamma forming. To the left and behind is another, slightly more recent cell. Precipitation is falling from both of these cells at 1 and 2.
On the left edge is another cumuliform cell identified as Cumulus congestus. This cell is just about to transition to Cumulonimbus calvus. More Cumulus in different stages of development can be seen in many areas.
Cumulonimbus are described as "cloud factories" that may produce patches of Cirrrus spissatus, Altocumulus, Altostratus or Stratocumulus.
