A High-level cloud portrait, cirrus, arranged in a parallel band that appears to converge towards the sky between the plant and a smaller tree. Whilst the photographed cloud variety look certain, the cloud species is more subjective looking like a hybrid between spissatus due to the cloud looking thick in the centre but still missing a grey base or shading and vertebratus in the outer edges especially on the right with some fish bone arrangement. The weather sounding on the second thumbnail indicated that this cloud developed at a height of between 8.6km and 12.3km, though certainly not covering all that height with some wind shear present. Analyzing the visible satellite image and surface pressure chart respectively on the following thumbnails, it was evident that the high clouds formed on the outer edges of a developing low pressure system over North Africa caused by strong sunshine. Such low pressure systems are normal for the Spring months. The first thumbnail is another photo of the high-level clouds taken at the end of the day showing cumuliform development probably due to daytime heating, also known as cirrus spissatus castellanus, some having a small anvil could be very small upper-level cumulonimbus cloud.
