Spectacular Video of Thick Fog Rolling In Over Greece’s Ioannina

A timelapse video captured the city of Ioannina in northwestern Greece gradually being blanketed by a thick layer of fog on Monday.

The city and Lake Pamvotis, the largest lake in Epirus, are seen disappearing under the radiational fog.

This type of fog is most prevalent during the fall and winter, forming overnight as the air near the ground cools and stabilizes. When this cooling causes the air to reach saturation, fog forms.
