Osona is a land of fog, as seen in The Readers' Photos of La Vanguardia. And this morning it shined again, although the star of the landscape was the parhelion, a rare luminous phenomenon that consists of the simultaneous appearance of several images of the sun reflected in the clouds and generally arranged symmetrically on a halo.
The day started with fog in Les Masies de Voltregà, as if he had woken up with sleep, but it became less so when the sun came out and the parhelion occurred.
Another phenomenon that has been seen has been a rainbow-style iridescence in the sky. Iridescence is caused by multiple reflections of light from multiple semitransparent surfaces, where subsequent phase changes and interference of the reflections modulate the light by amplification or attenuation of different wavelengths.
Depending on the angle at which the surface is illuminated, it will look different colors. Iridescence is very common in nature, we can easily see it in insects, birds and fish, and even in plants.
Iris, in Greek mythology, is the personification of the rainbow and messenger of the gods, who left a trail of luminous colors behind her.
Fog is a meteorological phenomenon that consists of the suspension of very small water droplets in the atmosphere or of moist hygroscopic particles, which reduce horizontal visibility to a distance of one kilometer or more.
If the meteorological phenomenon gives a vision of 1 km or less, it is considered fog; and if it allows you to see more than 1 km, the phenomenon is fog.
Furthermore, due to the phenomenon of thermal inversion we can observe that the smoke cannot rise higher than the fog and there comes a point when the smoke column is deflected downwards.
Fog, the Pubilla, the "baixa joke" are common in the Plana de Vic. Not in vain is Osona the area with the most days a year with this atmospheric phenomenon (at least a hundred). From the Pedronet de Bellmunt, at 1246 meters, there are also good views of this meteorological phenomenon.
From the sanctuary of Bellmunt you can also see a series of mountain ranges, among which stand out, in the north, the Rasos de Peguera massif, the Sierra del Cadí and the peaks of Pedraforca and Puigmal.
