Formation of lenticularis-like cloud as spotted over the southwestern side of Malta. These normally form in mountainous terrains. However, Malta itself does not have any mountains being elevated at only about 210 metres on the western side in which case might have been enough to trigger such cloud conditions in otherwise perfect weather conditions for such clouds to form. The largely inactive cold front passing over the Islands might have acted as a trigger for such clouds formation. The air being stable, the clouds were quickly layered into such a formation after passing over the cliffs. The first thumbnail shows a cloud photo that could have been a developing altocumulus or simply altostratus clouds taken at the same time on that evening. The second thumbnail shows the weather sounding at the time, the third thumbnail shows the surface pressure chart and the fourth thumbnail shows the surface wind field over the Mediterranean Sea at that time. The cloud formation explanation is subjective in this case and subject to interpretation. Of course, any cloud expert seeing this page, could give his or her interpretation of cloud formations.
