Cirrocumulus lacunosus and Cirrus fibratus
The image shows Cirrus fibratus and Cirrocumulus, which were spreading quickly from the south-west at the time of the photograph in a strong jet stream (wind >100 kt). Very small elements such as at 1 and 2, typical of Cirrocumulus, can be seen in several parts of the image. In the lower left of the image are several holes in the cloud (seen at 3 and 4), which identify it as the variety lacunosus.

At 1800 UTC, low pressure of 1 001 hPa was centred west of Ireland. The associated weakening occluded front had cleared the area that morning. The cloud was associated with an unusually strong summer jet stream (>100 kt).

The 1200 UTC ascent from Camborne, England, UK (WMO 03808), taken six hours earlier in the post-frontal air stream, shows a moist layer at Cirrus and Cirrocumulus levels and the strong summer jet stream.

The satellite image, captured 2.5 hours after the photograph, shows bands of upper cloud over south-east England, UK that had passed over southern England earlier in the evening.

Cirrocumulus lenticularis lacunosus
The image shows Cirrocumulus cloud at the zenith of the sky on an otherwise clear day. The cloud is a bright white without shading and is composed of small elements. It has an overall lens shape, indicative of the species lenticularis, with rather diffuse edges. The variety lacunosus with its fine-scale honeycomb structure can be seen in detail towards the top of the image. A sounding representative of the airstream suggests a cloud height of about 7 000 m.

Cirrocumulus lenticularis lacunosus
This zoomed-in image is of a section of Cirrocumulus cloud. It illustrates the typical structure of the variety lacunosus, with more or less regularly distributed round holes like a net or honeycomb.
