Local photographer, Chris Lyons, sent the Ross Gazette some photos he took of Ross-on-Wye on Wednesday, November 30th, covered in hoar frost.

A hoar frost is composed of tiny ice crystals and is formed by the same process as dew, but when the temperature of the surface is below freezing point.

The ’feathery’ variety of hoar frost forms when the surface temperature reaches freezing point before dew begins to form on it.

A ’white’ frost, composed of more globular ice, occurs when the dew forms first, then subsequently freezes.

The presence of fog tends to prevent the formation of hoar frost as it reduces the potential for radiational cooling of surfaces.
