The fog, far from disappearing, persists and resists in the Osona region, where day after day it is being noticed. It is known as the Pubilla de la Plana, but in some areas it is also known as the "baixa joke", when it is low and covers everything.
The Osona region is, in fact, the place in Spain with the most days of fog, a hundred a year. And lately the weather conditions are being created for it to persist.
The Pubilla de la Plana phenomenon, which can be accompanied by frost, can last for days and even weeks if conditions are favorable.
La Plana de Vic is an elongated depression in a north-south direction that constitutes the central nucleus of the Osona region (Barcelona). When cold air from higher altitudes descends and pools on this sunken plain, water vapor condenses into microscopic droplets. This is how a sea of fog is produced that is a characteristic part of the landscape, as seen in these photographs in La Vanguardia's Readers' Photos.
The city of Vic, located in its center, is the most important town in this area, which arose in this way: the Ter river and its tributaries, with its erosive action, much deeper in the eastern part than in the western part. , originated the Plana de Vic.
This depression has a total surface of 600 km2. It is completely surrounded by mountains, those of Ripollès and Garrotxa in the north; the Guilleries to the east; Montseny to the southeast; the Moianès and the Lluçanès towards the west. Therefore, it is closed by a ring of saws.
La Plana de Vic is a part of the valley of the Ter river at its exit from the Pyrenees, which moves from north to south for a stretch and turns east at Manlleu to head to Roda de Ter and cross the massif of the Guilleries, where the Sau reservoir is located.
Being a depression surrounded by mountains of more than a thousand meters high, it usually suffers from frequent fog in winter, especially in the low areas (Vic, Roda de Ter, Manlleu) and severe frosts when an invasion of air masses occurs. Arctic or Siberian storms followed by a calm meteorological situation.
This series of photographs were taken this past morning from Sant Bartomeu del Grau. You can see the fog of the Plana de Vic at sunrise.
The sanctuary of the Mare de Déu de Cabrera is located on a cliff in the heart of Collsacabra, very close to the town of Cantonigrós. It's winter, but it was a spring day when I captured these images of the seas of fog.
