The Osona region is a compendium of meteorological phenomena that draw the winter landscape through its roads and highways of fog and frost, as can be seen in this photographic report captured in Torelló for La Vanguardia Readers’ Photos.
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.
Osona is the area of ??Spain with the most days of fog per year (at least a hundred). In this region this phenomenon is called the Pubilla de la Plana de Vic or “baixa joke”.
Another phenomenon that appears in the winter landscape is frost, which consists of a drop in ambient temperature to levels below the freezing point of water and causes the water or vapor in the air to freeze, depositing in form of ice on the surfaces, as seen in Torelló’s snapshots.
The extreme case of frost is the black frost, which is when a frost occurs with greater pressure and even causes the plants to be completely destroyed.
