Hoar frost. View across a river valley,showing trees covered in hoar frost. This type of frost forms when air with a dew point below freezing point is cooled by radiative heat loss - for example on a clear night in winter. As the air becomes saturated below its dew point,the water vapour will sublimate forming tiny interlocking ice crystals on any cold surface. Photographed in Northumberland,UK | |
