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:
“The mayor and Montaigne have always been two, with a very clear separation. For all of being a lawyer or a financier, we must not ignore the knavery there is in such callings. An honest man is not accountable for the vice or stupidity of his trade, and should not therefore refuse to practice it.”
—Michel de Montaigne (1533–1592)
“Not to like ice cream is to show oneself uninterested in food.”
—Joseph Epstein (b. 1937)
