Hoar frost (3 o 3)

Hoar frost

This hoar frost on the Manorburn dam in Central Otago is caused by freezing fog. If the air temperature of a fog is below 0° C then the tiny water droplets remain in a liquid form. But if they come into contact with objects such as trees and leaves they freeze, covering surfaces with rime – known as a hoar frost.
