Clear ice refers to a solid precipitation which forms when air temperature is between 0 °C (32 °F) and -3 °C (27 °F) and there are supercooled, relatively large drops of water (from freezing fog). A rapid accretion and a slow dissipation of latent heat of fusion favor the formation of a transparent ice coating, without air or other impurities.
A similar phenomenon occurs when freezing rain or drizzle hit a surface and is called glaze.
Clear ice, when formed on the ground, is often called black ice, and can be extremely hazardous.
Clear ice is denser and more homogeneous than hard rime; like rime, however, clear ice accumulates on branches and overhead lines, where it is particularly dangerous due to its relative high density.
Famous quotes containing the words clear and/or ice:
“Earthly minds, like mud walls, resist the strongest batteries: and though, perhaps, sometimes the force of a clear argument may make some impression, yet they nevertheless stand firm, and keep out the enemy, truth, that would captivate or disturb them. Tell a man passionately in love, that he is jilted; bring a score of witnesses of the falsehood of his mistress, it is ten to one but three kind words of hers shall invalidate all their testimonies.”
—John Locke (1632–1704)
“She has been man’s slave. He has been educated at her expense. If he bought the ice cream, she was expected to pay for all his luxuries in reduced wages. She has done the drudgery and borne the insults of those who wronged her, assuming to be her protector.”
—Caroline Nichols Churchill (1833–?)
