The extraordinary meteorological event known as Caligo has once again made its presence felt in the Cinque Terre.
The spring-like temperatures, which soared above 15 degrees Celsius last Sunday in mid-February, have rejuvenated one of the region's most fascinating weather phenomena.
This event occurs when a flow of warmer air moves over the sea surface, which, at this time of year, has cooler temperatures around 13-14 degrees Celsius. The interaction between the warmer air and the cooler seawater causes evaporation, which then condenses quickly, forming tiny droplets of vapor.
When the air temperature reaches the dew point, the temperature at which air must be cooled at constant pressure for condensation to take place, fog is produced. This fog is then pushed toward the coast by sea breezes.S
This phenomenon are infrequent in the Cinque Terre, happening only two or three times a year, and each event leaves onlookers in awe.
