Icing Hazards - National Weather Service
The first structures to accumulate ice are the surfaces with thin leading edges: antennas, propeller blades, horizontal stabilizers, rudder, and landing gear struts. Usually the pencil-thin outside air temperature gauge is the first place where ice forms on an airplane.
Black ice - Wikipedia
Black ice, sometimes called clear ice, is a coating of glaze ice on a surface, for example on streets or on lakes. The ice itself is not black, but visually transparent , allowing the often black road below to be seen through it and light to be transmitted.
Freezing rain - Wikipedia
The resulting ice, called glaze ice, can accumulate to a thickness of several centimeters and cover all exposed surfaces. The METAR code for freezing rain is FZRA. A storm that produces a significant thickness of glaze ice from freezing rain is often referred to as an ice storm.
Weather & Atmosphere - Icing in the Aviation Environment
Glaze ice results from supercooled drops/droplets striking a surface but not freezing rapidly on contact. Glaze ice is denser, harder, and sometimes more transparent than rime ice. Factors, which favor glaze formation, are those that favor slow dissipation of the heat of fusion (i.e., slight supercooling and rapid accretion).

2022年3月22日 · At the early stage of the water film development in the unsteady model, the film is thin with a small runback region, leading to a small extent of the glaze ice. As the time goes by, the runback water region, as well as the glaze ice extent, gradually increases with the movement of the runback limits.

2024年1月1日 · Glaze Ice: Unlike its rime counterpart, glaze ice emerges under conditions of marginally elevated temperatures (Addy et al., 1997). Environments rich in sizeable water droplets, abundant liquid water, and propelled by high air speeds delay the immediate freezing of water droplets upon wing contact.
Sea Ice Glossary - Woods Hole Oceanographic Institution
As this soup thickens, a thin film of ice known as grease ice forms. This film is strong enough to support the weight of a seabird, and can ripple with the waves passing beneath. As the surface temperature continues to drop, the ice forms a solid layer and is then called pack ice.
Glaze (ice) - WikiMili, The Best Wikipedia Reader
2024年6月7日 · Glaze or glaze ice, also called glazed frost or verglas, is a smooth, transparent and homogeneous ice coating occurring when freezing rain or drizzle hits a surface. It is similar in appearance to clear ice, which forms from supercooled water droplets.

Weather Facts: Glaze and Black Ice | weatheronline.co.uk
Glaze is a thin coating of ice that forms when supercooled liquid precipitation, such as freezing rain or drizzle, fall onto exposed objects whose temperature is below or slightly above freezing. Although the droplets freeze almost instantly, they have sufficient time to spread out into a thin layer before doing so.
