Sentences with phrase «as snow grains»

Smaller - sized graupels are generally referred to as snow grains.

Not exact matches

At the same time, as the snow melts and refreezes, the grains of snow get larger.

Two properties dominate reflectivity in dry snow — the size of snow grains, which become larger and more absorbent as they melt, and the presence of dark impurities that absorb the sun's energy, predominantly black carbon and mineral dust, which also cause the snow to melt faster.

«When snow first falls, snow grains are quite small, and as snowpack ages, and particularly for warmer snowpack, you get consolidation of those grains into larger clumps,» said Sarah Doherty, a researcher at the University of Washington who co-authored the paper.

Two possible ways that the inner solar system received water are: water molecules sticking to dust grains inside the «snow line» (as shown in the inset) and carbonaceous chondrite material flung into the inner solar system by the effect of gravity from protoJupiter.

When firn is buried beneath subsequent snow accumulations, density increases as air spaces between the crystals are reduced by mechanical packing and plastic deformation until... interconnected air passages between grains are sealed off into individual air bubbles (Herron and Langway, 1980).

The data include soluble ions (sodium and non-sea-salt sulfate) and dust particle concentrations, as well as major oxide geochemistry of tephra grains isolated from snow samples.

Green foods include dark green vegetables such as spinach, kale, chard, lettuces, green beans, snap peas, snow peas, broccoli; green herbs such as parsley; sea vegetables such as spirulina, seaweed, blue green algae; sprouted grains and seeds, such as alfalfa and sunflower sprouts; cereal grasses such as wheatgrass and barley grass.

Freshly fallen snow reflects up to 84 percent of incoming sunlight, but during the warm season the reflectivity declines as the ice grains within the snowpack change shape and size.

When firn is buried beneath subsequent snow accumulations, density increases as air spaces between the crystals are reduced by mechanical packing and plastic deformation until... interconnected air passages between grains are sealed off into individual air bubbles (Herron and Langway, 1980).

Poorly characterized mechanisms driving both production and destruction of GEM in the interstitial air of snowpacks depend on environmental conditions (irradiation, temperature, and presence of water layer around snow grains) and the chemical composition of snow (e.g., presence of halogens or divalent mercury species as a consequence of surface deposition)(25).

The more soot, the more darkening, but as little as a few parts per billion by weight reduces the albedo of pure snow (that is, collections of grains of ice) by a few per cent in the visible part of the spectrum.

Even though the TV signal has been captured as cleanly as possible, there will still be some flaws in the image such as snow or noise (think film grain).
