The Osona region has once again become an ocean of seas of fog, quite a spectacle if viewed from the different viewpoints, such as Morro de la Miranda, as we see in these photographic reports in Las Fotos de los Lectores de La Vanguard.
In some areas, the popular "Pubilla de la Plana de Vic" is also known as "baixa joke". Basically, it's when a sea of fog comes down and covers everything.
It must be borne in mind that the Osona region is the place in Spain with the most foggy days, around a hundred a year.
The phenomenon of the Pubilla de la Plana, which can be accompanied by frost, can last days and even weeks if the conditions are favourable.
La Plana de Vic is an elongated depression in a north-south direction that constitutes the central core of the Osona region (Barcelona). When the cold air from the higher parts descends and stagnates in this sunken (flat) plain, the water vapor condenses into microscopic droplets. This is how a sea of fog is produced that is a characteristic part of the landscape, as can be seen in the photographs.
The River Ter and its tributaries, with their 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.
