Needle ice phenomena play a particularly significant role in patterned ground in periglacial environments. [8] The growth of needle ice lifts a detached, frozen soil crust riding on top of the layer of ice. When the crust and the ice melt, the soil surface settles back irregularly. This phenomenon is linked to erosion, particularly on ...
Laminations of ice in a sheet of aufeis. Aufeis (/ ˈ aʊ f aɪ s / OW-fysse) (German for "ice on top") is a sheet-like mass of layered ice that forms from successive flows of ground or river water during freezing temperatures. This form of ice is also called overflow, icings, [1] or the Russian term, naled (Russian: наледь).
This kind of dependence is called "grounding" to distinguish it from other kinds of dependence, such as the dependence of an effect on its cause. It is sometimes called metaphysical or ontological dependence. Grounding can be characterized as a relation between a ground and a grounded entity.
Photograph taken 21 March 2010 in Norwich, Vermont. Frost heaving (or a frost heave) is an upwards swelling of soil during freezing conditions caused by an increasing presence of ice as it grows towards the surface, upwards from the depth in the soil where freezing temperatures have penetrated into the soil (the freezing front or freezing boundary).
A type of solid precipitation which forms when relatively large drops of water are supercooled into a dense, transparent coating of ice without air or other impurities. It is similar to glaze and hard rime and, when formed on the ground, is often called black ice. clear-air turbulence climate
Types of frost flowers include needle ice, frost pillars, or frost columns, extruded from pores in the soil, and ice ribbons, rabbit frost, or rabbit ice, extruded from linear fissures in plant stems. [1] The term "ice flower" is also used as synonym for ice ribbons, but it may be used to describe the unrelated phenomenon of window frost as well.
An ice spike is an ice formation, often in the shape of an inverted icicle, that projects upwards from the surface of a body of frozen water. Ice spikes created by natural processes on the surface of small bodies of frozen water have been reported for many decades, although their occurrence is quite rare.
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.
