In Las Fotos de los Lectores de La Vanguardia we can see the spectacular sunrise with the fog covering the Plana de Vic, a phenomenon from which only the highest peaks of the mountains and the birds manage to escape.

As can be seen in the snapshots, the so-called Pubilla de la Plana covers the entire plain, while above this thick layer of fog the sky is clear, furrowed by flocks of birds.

In some areas, the popular Pubilla de la Plana de Vic, that is, the Osona fog, is also known as “baixa joke”. Basically, it’s when a sea of ​​fog comes down and covers everything. We can see it in detail in this photograph of the town covered in fog at ground level.

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. And we must bear in mind that the Osona region is the place in Spain with the most foggy days, a hundred a year.

The orange sky at dawn is due to the glare, a meteorological phenomenon in which the clouds in the sky show a wide palette of colors that goes from pink to the most intense orange.

As part of the phenomenon of scattering of sunlight, in the morning and afternoon hours, when the sun is closer to the horizon, the light that reaches Earth is soft tones, such as orange.
