A very beautiful and colourful sunset due to the setting sun shining on the back of altocumulus catellanus clouds and illuminated further by high clouds. The mid-level cloud formation was induced by a line of bad weather (solid black line) associated with a young low pressure system that was moving towards the Maltese Islands as per fourth thumbnail. The first thumbnail shows the same sunset photo as the sun had set further giving the same clouds a completely different colour to violet unlike the yellow earlier on. The second thumbnail shows cirrocumulus or most probably upper-level altocumulus undulatus clouds that was taken an hour before this sunset. This wave-like (undulation) formation was due to lots of wind shear in the atmosphere (increasing wind speed with height) as can be seen in the weather sounding on the third thumbnail. Varying wind speed above and below this cloud layer caused the clouds to rotate in itself and therefore bunching up in parallel ridges. Rapidly increasing wind speed with height (Wind speed shear) was the result of an overhead strong jet stream running above the Maltese Islands as per fifth thumbnail. The explained weather conditions have therefore combined together to produce this spectecular sunset which was quite unique for the Islands.
