Hoar frost on a wire fence. Hoar frost forms in a similar way to dew,in that water is deposited from air that is supersaturated with water vapour. This can occur when moist air cools rapidly. The difference here,is that the temperature of the surface on which the deposition occurs is below the freezing point of water. This results in the formation of many needle-like ice crystals. Hoar frost forms in still,clear and cold weather | |
