Rime ice also forms when ice forms on the surface of an aircraft, particularly on the leading edges and control surfaces when it flies through a cloud made of supercooled water liquid droplets. Rime ice is the least dense, milky ice is intermediately dense and clear ice is the most dense. All forms of ice can spoil lift and may have a ...
Rime ice is rough and opaque, formed by supercooled drops rapidly freezing on impact. Forming mostly along an airfoil 's stagnation point , it generally conforms to the shape of the airfoil. Mixed ice is a combination of clear and rime ice, having both properties.
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 relatively high density .

Rime is a type of ice deposition that occurs quickly, often under heavily humid and windy conditions. [8] Technically speaking, it is not a type of frost, since usually supercooled water drops are involved, in contrast to the formation of hoar frost, in which water vapour desublimates slowly and directly.
Oct. 31—The crisp scrape of steel on a turquoise surface. Towering snow-dusted mountains bathed in golden light. Frozen water clear enough to spot fish and boulder gardens underfoot.
Most Americans believe President-elect Donald Trump will push the U.S. government deeper into debt in his new term, though most Republicans do not share Democrats' concerns over his fiscal ...
Ice loads are a major cause of catastrophic failures of overhead electrical power lines, as power lines can break under the sheer weight of accumulated ice. Therefore, estimation of maximum potential ice load is crucial in the structural design of power line systems to withstand ice loads, [ 4 ] and this can be done with numerical icing models ...
