Cc stratiformis

Actually this is a rare formation of cirrocumulus clouds known as “Cirrocumulus stratiformis undulatus cavum”. From the panoramic photo, the cavum subspecies is hard to identify but a closeup photo of the cirrocumulus clouds as seen on the first thumbanil was taken and it became clear that there was a gap in this cloud cover which might or might not have been caused by an aeroplane. This gap in the clouds indicate that the cloud droplets were actually supercooled water, in a liquid state, at a temperature well below 0°C. Once these found dirt molecules to bind on, they seemed to become arranged in an undulatus formation due to the strong winds of 120kmh in the cloud’s altitudes. At that level, lots of wind shear was found in the weather sounding on the third thumbnail. Both of the photographed clouds were distinguished from the approaching altocumulus clouds in the second thumbnail by the cloud’s elements having an apparent width of less than 1° when to compared to lower cloud levels. A low pressure system was still present over North Africa bringing yet another mild day over the Islands. Hence it was ascertained that the photographed clouds (main photo and first thumbnail) could be found at altitudes of between 250mb and 200mb whilst the second thumbnail of altocumulus clouds were formed at the 450mb altitude.
