  2. Sublimation (phase transition) - Wikipedia

    en.wikipedia.org/wiki/Sublimation_(phase_transition)

    The sublimation that occurs at the solid-gas boundary (critical sublimation point) (corresponding to boiling in vaporization) may be called rapid sublimation, and the substance sublimes rapidly. The words "gradual" and "rapid" have acquired special meanings in this context and no longer describe the rate of sublimation. [citation needed]

  3. Alcove (landform) - Wikipedia

    en.wikipedia.org/wiki/Alcove_(landform)

    Annually in the North Pole region, alcove formation is most active during autumn and winter seasons and also form specific alcove-apron regions during springtime sublimation. This is when the alcoves start at the edge of dunes and deposit and end into an apron fan shape. [ 3 ]

  4. Wegener–Bergeron–Findeisen process - Wikipedia

    en.wikipedia.org/wiki/Wegener–Bergeron...

    The Wegener–Bergeron–Findeisen process (after Alfred Wegener, Tor Bergeron and Walter Findeisen []), (or "cold-rain process") is a process of ice crystal growth that occurs in mixed phase clouds (containing a mixture of supercooled water and ice) in regions where the ambient vapor pressure falls between the saturation vapor pressure over water and the lower saturation vapor pressure over ice.

  5. Water cycle - Wikipedia

    en.wikipedia.org/wiki/Water_cycle

    The strength of the water cycle and its changes over time are of considerable interest, especially as the climate changes. [26] The hydrological cycle is a system whereby the evaporation of moisture in one place leads to precipitation (rain or snow) in another place. For example, evaporation always exceeds precipitation over the oceans.

  6. Evapotranspiration - Wikipedia

    en.wikipedia.org/wiki/Evapotranspiration

    Evapotranspiration does not, in general, account for other mechanisms which are involved in returning water to the atmosphere, though some of these, such as snow and ice sublimation in regions of high elevation or high latitude, can make a large contribution to atmospheric moisture even under standard conditions.

  7. Snow science - Wikipedia

    en.wikipedia.org/wiki/Snow_science

    The following processes have the corresponding results: smooth—deposition without wind; wavy—wind deposited snow; concave furrows—melt and sublimation; convex furrows—rain or melt; random furrows—erosion. Snow covered area (SCA) describes the extent of snow-covered ground, usually expressed as a fraction (%) of the total.

  8. Polygonal patterned ground - Wikipedia

    en.wikipedia.org/wiki/Polygonal_patterned_ground

    Low center polygons are thought to develop from the high center polygons. The troughs along the edges of high center polygons may become filled with sediment. This thick sediment will retard sublimation, so more sublimation will take place in the center that is protected by a thinner lag deposit. In time, the middle becomes lower than the outer ...

  9. Water vapor - Wikipedia

    en.wikipedia.org/wiki/Water_vapor

    Dew point temperature and relative humidity act as guidelines for the process of water vapor in the water cycle. Energy input, such as sunlight, can trigger more evaporation on an ocean surface or more sublimation on a chunk of ice on top of a mountain. The balance between condensation and evaporation gives the quantity called vapor partial ...
