Blue iceberg observed by tourists along the coast of Alaska, 2010. A blue iceberg is visible after the ice from above the water melts, causing the smooth portion of ice from below the water to overturn. [1] [2] The rare blue ice is formed from the compression of pure snow, which then develops into glacial ice. [3] [4]
That is, any snow that falls in that area is counteracted by sublimation or other losses. Such areas are known as blue-ice areas. [3] These areas have been used as blue ice runways (e.g. Wilkins Runway, Novolazarevskaya, Patriot Hills Base Camp) due to their hard surface, which is suitable for aircraft fitted with wheels rather than skis.
A blue-ice area in the Miller Range with a meteorite. A blue-ice area is an ice-covered area of Antarctica where wind-driven snow transport and sublimation result in net mass loss from the ice surface in the absence of melting, forming a blue surface that contrasts with the more common white Antarctic surface.
But the science behind a blue sky isn't that easy. For starters, it involves something called the Rayleigh effect, or Rayleigh scattering. But that same phenomenon can also sometimes make skies ...
Snow can be compacted to form a snow road and be part of a winter road route for vehicles to access isolated communities or construction projects during the winter. [78] Snow can also be used to provide the supporting structure and surface for a runway, as with the Phoenix Airfield in Antarctica. The snow-compacted runway is designed to ...
Snow occurs when the atmosphere is "cold" all the way from the clouds to down here at the surface. And rain occurs when it's "warm" all the way from the clouds to the surface.
Conversely, in Russian and some other languages, there is no single word for blue, but somewhat different words for light blue (голубой, goluboy) and dark blue (синий, siniy). Other color names assigned to bodies of water are sea green and ultramarine blue. Unusual oceanic colorings have given rise to the terms red tide and black tide.
The most snow in a season in New Orleans is only 2.7 inches, which took place in 1963-64. In Houston, the highest seasonal snowfall total is 4.8 inches in 1973-73. 4) Don't Forget the Ice
