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:
“It is only too clear that man is not at home in this universe, and yet he is not good enough to deserve a better.”
—Perry Miller (1905–1963)
“We may prepare food for our children, chauffeur them around, take them to the movies, buy them toys and ice cream, but nothing registers as deeply as a simple squeeze, cuddle, or pat on the back. There is no greater reassurance of their lovability and worth than to be affectionately touched and held.”
—Stephanie Martson (20th century)
