Hoar frost, Lewis Pass

Hoar frost, Lewis Pass

In the winter, a cloudless anticyclone can also allow frost to develop. This occurs because the cold land causes the air to freeze. If water condenses onto vegetation at temperatures below freezing, then the moisture freezes and a hoar frost is created.
