Huurre syntyy lakimäntyyn - Frozen dew in Scots pine

When the supercool clouds sweep in minus temperatures over the fell top, a remarkable layer of frozen dew is formed onto the trees that are growing as scattered near to the top. In a weather situation like this there is not enough water and condensation nuclei in the air for formation of snow. Instead, upon colliding the tree top the supercool water in the clouds condenses into frozen dew, like in the case of Scots pine in the photo. The photo was taken on top of Varrio I fell, towards north-west.
