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:
“Yes, but I do not travel to find comfortable, rich, and hospitable people, or clear sky, or ingots that cost too much. But if there were any magnet that would point to the countries and houses where are the persons who are intrinsically rich and powerful, I would sell all, and buy it, and put myself on the road to-day.”
—Ralph Waldo Emerson (1803–1882)
“People in Stamps used to say that the whites in our town were so prejudiced that a Negro couldn’t buy vanilla ice cream. Except on July Fourth. Other days he had to be satisfied with chocolate.”
—Maya Angelou (b. 1928)
