Soft Rime


Definition: Soft rime: Fragile rime consisting mainly of thin needles or scales of ice.


Near the ground, soft rime is deposited under calm or low-wind conditions on all sides of exposed objects. Soft rime easily drops if an object is shaken. It mainly forms with ambient air temperatures lower than –8 °C. At temperatures well below –8 °C, the formation of soft rime does not necessarily require the presence of fog.
