Med Cyclone cumuliform

Swirling cumuliform clouds as the eye of a Mediterranean cyclone passed directly over the Maltese Islands as depicted by the visible satellite image. Such cyclones unlike truly tropical cyclones form due to incursions of cold air following a cold front (as depicted by the surface pressure chart) passing over a relatively warm sea. Wind shear needs to be as low as possible while the air must be very humid at great depths of the atmosphere in order for the cyclone to form. The weather sounding showed that the latter two conditions were satisfied as days of continuous precipitation around the Maltese Islands led to a pool of very moist air over the Maltese Islands while the cold front had lessened wind shear from earlier in the day as it veered winds towards the SW at great depths of the atmosphere. Hence, a cyclone was formed. Note that such cyclones are warm-core in the sense that warm, light air in the centre is surrounded by colder, swirling winds with gusts measuring up to 120kmh (Force 12) in this case. Such cyclone was a very first for Malta as the eye had never passed directly over the Islands. According to some research, the Mediterranean Sea might begin to expirience tropical-like cyclones by the year 2100 if the sea continues to warm up at its current pace though this would still be a rare meteorological phenomena. This link will direct you to a small video of the very bad weather taken by me. The first thumbnail shows the weather as the cyclone was approaching Malta from the west (in this case the background is showing heavy clouds) and was taken sideways in order to depict as much of the sky as possible. A search using the keywords `7 November 2014 Mediterranean Cyclone` will provide further information. Further weather charts than those shown in the thumbnails herewith are available upon request. These include a visible satellite image taken at 1600 CET and a close-up satellite image of the eye of the cyclone, two different 500mb charts, cloud top temperature chart, an 850mb chart depicting cold pool of air in the Mediterranean, a Rain radar image and sea-level pressure from Malta`s Met Office during the cyclone.
