  2. Accumulation zone - Wikipedia

    en.wikipedia.org/wiki/Accumulation_zone

    The accumulation zone is found at the highest altitude of the glacier, where accumulation of material is greater than ablation. On a glacier , the accumulation zone is the area above the firn line, where snowfall accumulates and exceeds the losses from ablation , ( melting , evaporation , and sublimation ).

  3. Snow - Wikipedia

    en.wikipedia.org/wiki/Snow

    Extreme snow accumulation on building roofs. Snow is an important consideration for loads on structures. To address these, European countries employ Eurocode 1: Actions on structures - Part 1-3: General actions - Snow loads. [85] In North America, ASCE Minimum Design Loads for Buildings and Other Structures gives guidance on snow loads. [86]

  4. Snow line - Wikipedia

    en.wikipedia.org/wiki/Snow_line

    The climatic snow line is the boundary between a snow-covered and snow-free surface. The actual snow line may adjust seasonally, and be either significantly higher in elevation, or lower. The permanent snow line is the level above which snow will lie all year.

  5. Snow hydrology - Wikipedia

    en.wikipedia.org/wiki/Snow_hydrology

    Snow Depth-This is a measurement from the snow surface to the ground in meters. It is commonly does over a large time span using immobile graduated stakes. Snow Water Equivalency- A measuring tool which represents the vertical depth of water that would accumulate in an area, if all the snow and ice were melted in that given area.

  6. Glacier mass balance - Wikipedia

    en.wikipedia.org/wiki/Glacier_mass_balance

    This definition means that the accumulation rate is greater than the ablation rate during the accumulation season, and during the ablation season the reverse is true. [11] A "balance year" is defined as the time between two consecutive minima in the glaciers mass—that is, from the start of one accumulation season through to the start of the next.

  7. Glaciology - Wikipedia

    en.wikipedia.org/wiki/Glaciology

    This is caused mainly due to a long lasting accumulation period on subpolar glaciers frozen to the ground in the accumulation area. When the stress due to the additional volume in the accumulation area increases, the pressure melting point of the ice at its base may be reached, the basal glacier ice will melt, and the glacier will surge on a ...

  8. Snow science - Wikipedia

    en.wikipedia.org/wiki/Snow_science

    Snow water equivalent (SWE) is the depth of water that would result if the snow mass melted completely, whether over a given region or a confined snow plot, calculated as the product of the snow height in meters times the vertically-integrated density in kilograms per cubic meter.

  9. Classifications of snow - Wikipedia

    en.wikipedia.org/wiki/Classifications_of_snow

    Snow accumulation on ground and in tree branches in Germany Snow blowing across a highway in Canada Spring snow on a mountain in France. Classifications of snow describe and categorize the attributes of snow-generating weather events, including the individual crystals both in the air and on the ground, and the deposited snow pack as it changes over time.
