  Cirrus fibratus intortus, Cirrus spissatus and Altocumulus

  Very irregularly curved white filaments of Cirrus fibratus dominate this image. The filaments are sufficiently irregularly curved and entangled to suggest a mild form of the variety intortus. The Cirrus fibratus appears to have evolved from Cirrus floccus, a few elements of which are low on the horizon. There is also a small line of Cirrus castellanus, a thin sheet of Altocumulus and, right on the horizon, two contrails. With a depression lying to the south-west of the British Isles and a trough extending over England, UK, the day was showery over south-west England, with a morning thunderstorm and extensive convective cloud. The extreme coastal areas remained mostly sunny during the afternoon.

  Cirrus fibratus, increasing

  Following a sunny and warm afternoon, Cirrus fibratus at 1 and 2 spread rapidly across the sky from the west in advance of an occluded front. Some dense entangled filaments of the variety intortus are seen in the centre and an aircraft condensation trail is visible to the lower left of the image.
