Extra Information Under clear frosty nights in winter soft ice crystals might form on
vegetation or any object that has been chilled below freezing point by
radiation cooling. This deposit of ice crystals is known as hoar frost and
may sometimes be so thick that it might look like snow. The interlocking
ice crystals become attached to branches of trees, leafs, hedgerows and
grass blades and are one of the most prominent features of a typical
'winter wonderland' day. However, the fine 'feathers', 'needles' and
'spines' might also be found on any other object that is exposed to
supersaturated air below freezing temperature. Your Available Options |
