Hard rime is a white ice that forms when the water droplets in fog freeze to the outer surfaces of objects. It is often seen on trees atop mountains and ridges in winter, when low-hanging clouds cause freezing fog.

2021年1月5日 · Rime ice can be classified as either hard or soft and will generally depend on the wind strength. Hard rime ice is very dense and trees appear to be flocked with the crystals. This occurs due to freezing fog when wind speeds are high, and temperatures range between 17-28°F.

Hard rime is a white colored ice caused by water droplets in fog freezing to the outer surfaces of objects. It occurs when low clouds cause freezing fog, and can be found on trees, atop mountains and high ridges in winter.

2018年12月11日 · When supercooled droplets freeze and attach onto an exposed surface, you get rime ice. It can be classified as either hard or soft. All objects impacted need to be at 32°F or below causing the liquid to freeze instantly.

Definition: Hard rime: Granular rime, usually white, adorned with crystalline branches of grains of ice. Hard rime is formed by the rapid freezing of supercooled water so that the droplets freeze more or less individually, leaving air gaps. Near the ground, it is deposited mainly on objects exposed to at least moderate wind.

• Hard rime, which is whiter, denser, and brittle, also forms from freezing fog, but usually only in high winds of the sort that pummel WNC’s high mountain peaks. • Rime has been referred to by other names, including “frozen fog” and “frost feathers.”

2018年3月15日 · Hard rime usually freezes along the sides facing the wind among trees, buildings, and any other solid objects. For hard rime to form, it requires an air temperature that is less than 29 degrees Fahrenheit. In most cases higher than 17 degrees Fahrenheit will cause it.

Hard rime is more compact and amorphous than soft rime and may build out into the wind as glazed cones or ice feathers. The icing of ships and shoreline structures by supercooled spray from the sea usually has the characteristics of hard rime.

Hard rime is a white ice that forms when the water droplets in fog freeze to the outer surfaces of objects. It is often seen on trees atop mountains and ridges in winter, when low-hanging clouds cause freezing fog.

2018年2月25日 · From AMS, rime ice is defined as “a white or milk and opaque granular deposit of ice formed by the rapid freezing of super-cooled water drops as they impinge upon an exposed object.” Opposed to glaze ice, rime tends to be much lighter and fluffier.
