LE IMMAGINI DELL'EUROPEAN METEOROLOGICAL CALENDAR 2014

COPERTINA Christmas-like ambience in Antarctica during mid-summer, on board the ”Polarstern“, Atka Bay, on route to Neumayer Station III, 21 December 2012 Photographer: Nina Machner Within minutes the weather showed its many sides, ranging from a radiant blue sky to a thick wall of fog. The wind swept across the sea with up to 11 Bft, and generated waves up to 8 metres in height. The temperature was mostly around the freezing point. The turbulent waters and melting processes have left their mark on the drifting iceberg, whose shape has considerably changed over time. The rough sea, for example, has carved cavities into it. The overall white appearance of icebergs is caused by light reflecting in air enclosed in the ice. Icebergs are also often streaked with veins of clear blue ice, which consist of meltwater that has seeped into glacier crevasses and has then frozen again.

GENNAIO Fairytale view, Tegelberghaus mountain hut, Eastern Allgäu, Bavaria (1,707-m altitude): View towards Füssen, Schwangau and Lake Forggensee, 24 January 2014 Photographer: www.foto-webcam.eu A blanket of high-lying fog lies over both the slopes of the mountain beneath the webcam’s position and Lake Forggensee somewhat to the north. Lying between them, the mostly illuminated valley between Füssen and Schwangau is almost free of fog. Particularly as a result of the patches of fog lit from below, this creates an almost fairytale-like landscape.

FEBBRAIO Solar storm, Kirkjufell, Snaefellsnes Peninsula, Iceland, 7 November 2012 Photographer: Dennis Polkläser Considerable Northern Lights activity was forecast for this night and, following previous attempts to observe them that, however, were less successful as a result of the weather, hopes were high that the weather forecast would prove to be correct. With increasing darkness, an initially faint glow in the starlight sky suddenly transformed into a brightly shimmering auroral band that extended right over the Kirkjufell, a pyramid-shaped mountain. During the course of the evening the aurora borealis continually increased in intensity and, after more than one hour, the band finally broke and illuminated the entire sky in an eerie green colour that was reflected in the snow.

MARZO Sea of clouds, near Malaga, Spain, 23 December 2012 Photographer: Juan Ortiz Rivas The evening before Christmas Eve 2012, the meteorological situation over the South of Spain was marked by the presence of stability. Low clouds appeared near the coast. From the mountains we could enjoy a great image of the sea of clouds, which fell from the mountains surrounding the city of Malaga.

APRILE Cloud curl, Gran Canaria, 1 May 1 2011 Foto: Fernando Bullón Miró Although it had been raining heavily the evening and night before, the first day of May began with an intensely blue sky, just a few clouds above the ocean and no clouds over the island. The heat from the sun caused sea breezes to blow inland, whereby several low clouds formed above the mountains. In the picture we can see one of these first clouds above the island’s interior, caused by currents of air ascending the mountains. When I saw the cloud vortex I took the picture as quickly as possible because I feared that it would only last for a very short time. And that’s exactly what happened: a few seconds after taking the picture the cloud had completely lost its amazing shape.

MAGGIO Lightning, Vicar, Almería, Spain, 19 June 2012 Photographer: José Miguel García García Numerous thunderstorms cells developed north of Vicar, whereby the thunderstorm activity lasted for seven hours! Although most of the cells were dry or with very little precipitation, they were accompanied by considerable lightning that was sometimes very intense and close to where I was standing. The lightning caused several fires in the mountains of Gador. The fire caused by this bolt of lightning lasted for one hour until one of the last cells crossed over the area. Fortunately this cell contained enough water to extinguish the fire.

GIUGNO  Painted clouds, near Barcelona, Spain, 21 December 2011 Photographer: Jordi Martín García Shortly after taking off from Barcelona Airport, Spain, we had the feeling that anyone who enjoys meteorology was about to experience an interesting day in terms of the weather. When we reached an altitude of 18,000 ft (around 6,000 m) our wishes came true: the first light of day illuminating these altocumuli lenticulari, plus the extra bonus of being able to see the contrail from another aeroplane that had just crossed our route to Madrid a few moments before, made us feel particularly privileged that we were able to enjoy such spectacular views during this early morning flight.

LUGLIO  Thunderstorm with anvil, near Barcelona, Spain, August 5, 2012 Photographer: Felipe G. Fuertes Rodríguez   As usual, the summer of 2012 was very hot in Spain. In particular, the hot air at ground level provided one of the ingredients for a very explosive cocktail. During the first weekend of August a cold front crossed the Iberian Peninsula giving us our second ingredient for our meteorological cocktail: high-level cold air. The formation of a low depression between Catalonia and the Balearic Islands then provided the third and decisive component: humid air from the Mediterranean Sea („Sistema Ibérico“). This combination resulted in the formation of clouds with a high vertical extent in the mountainous regions. This photograph was taken in front of a powerful cumulonimbus capillatus with extreme meteorological characteristics such as intense rain, hail and strong winds.

AGOSTO Summer sunset, Kirkjufellfoss, Snaefellsnes Peninsula, Iceland, 4 May 2012 Photographer: Dennis Polkläser After a short and icy night in the car with barely a moment’s sleep, and the thermometer showing a temperature just over the freezing point, I started to use the early light to take photographs at around 2:40 am. At this altitude there is no longer any complete darkness by the beginning of May. Following a prolonged and intensive sunset during the previous evening, a narrow strip of light remained on the horizon that increased in intensity again shortly after midnight. This photograph was taken around 3:00 am, roughly two hours before sunrise.

SETTEMBRE  Late-summer fair weather clouds, Erzgebirge mountains (Saxony), 26 August 2012 Photographer: Jan Oesen The contrast between the blue sky, pale blue clouds and the harvested yellow cornfield creates an ambiance typical of later-summer weather conditions. The sun is to the rear of the photographer so that the straw bales on the field cast short shadows to the left, i.e. towards the west from where the clouds are gathering. On this day the temperature increased further to around 23°C before a cold front eventually brought rain and cooler temperatures during the evening.

OTTOBRE    End of the earth, Cape Finisterre, Spain, 7 November 2012 Photographer: José Antonio Quirantes Calvo An extensive layer of altocumulus stratiformis approached Cape Finisterre from the southwest. Six hours later it rained over the area. The cape is a rocky peninsula on the Atlantic Coast of Spain in the province of Coruña. The name Cape Finisterre is derived from the Latin “Finis Terrae”, which means “end of the earth”. During the Roman Empire, the cape was believed to be the westernmost point of the Iberian Peninsula and thus the known world. This is not actually correct because “Cabo da Roca” in Portugal is about 16.5 km further to the west. Nevertheless the place has a magical and mysterious quality about it and is steeped in legend. At the foot of the cape, the Atlantic Ocean is always impressive and defiant.

NOVEMBRE Aurora borealis, Tromsø, Northern Norway, 4–5 September 2012, midnight Photographer: Hanneke Luijting This photo was taken around midnight, September 4-5, 2012. The days are getting shorter by then, but the twilight still lasts all night – resulting in a beautiful blue colour in the sky. It‘s a pleasure to watch the aurora on a mild night like this: the temperature was around 9 degrees Celsius! Later in the season, it‘s a challenge to stay warm when photographing the aurora on cold winter nights. These auroras were the result of a massive solar storm which caused active auroras for several days in a row.

DICEMBRE Iceberg in Disko Bay near Ilulissat (Greenland), 9 July 2009 Photographer: Jürgen Löffelsender Even in summer, a mirror-like ocean and a clear blue sky are very rare in southern Greenland. It looks as if you can also see the iceberg beneath the water surface, but that is actually a reflection of the upper part above the water, whereby seven times as much ice lies beneath the surface. The iceberg is bathed in the yellow glow of the low-lying sun. With its tapered surface, it has the typical shape of an Arctic iceberg. In the Antarctic, on the other hand, tabular icebergs predominantly occur that have broken off from ice shelves (see title image).
