Glacier

Meteorology GlaciationGlacier winds

glacier ice"Any ice that is or was once a part of a glacier. It has been consolidated from firn by further melting and refreezing and by static pressure.

 


Glacier: A large mass of freshwater ice originally of atmospheric origin that forms on land over many years.

Glacier - a large body of ice moving slowly down a slope or valley or spreading outward on a land surface
Glaciation - the condition that exists when land is covered with glaciers ...

GLACIER WINDS
Air flow that descends from glaciers, occasionally at a high rate of speed.

Glacier Dammed Lake The lake formed when a glacier flows across the mouth of an adjoining valley and forms an ice dam.
Glaze Ice formed by freezing precipitation covering the ground or exposed objects.

Glacier Wind
A shallow downslope wind above the surface of a glacier, caused by the temperature difference between the air in contact with the glacier and the free air at the same altitude.

glacier: a large mass of ice (at least .1km^2) set in motion by the Earth's gravity, which is a result of accumulated snowfall with little snow melt.

Glacier A multi-year surplus accumulation of snowfall in excess of snowmelt on land and resulting in a mass of ice at least 0.1 km2 in area that shows some evidence of movement in response to gravity. A glacier may terminate on land or in water.

Glaciers are recognized as being among the most sensitive indicators of climate change, advancing substantially during climate cooling (e.g., the Little Ice Age) and retreating during climate warming on moderate time scales.

Glacier - A large piece of ice that survives for many years, slowly carving out the face of earth.
Glaze - A coating of ice, usually clear and smooth, formed on exposed objects by the freezing of rain, drizzle, or fog.

Glacier(2)
River of ice that under pressure can deform and flow plastically.

A piece of a glacier which has broken off and is floating in the sea.

GlacierIn hydrologic terms, bodies of land ice that consist of recrystallized snow accumulated on the surface of the ground, and that move slowly downslope.

Firn (Snow)In hydrologic terms, old snow on top of glaciers, granular and compact and not yet converted into ice. It is a transitional stage between snow and ice. Also called Neve.

In this period, glaciers and ice sheets receded greatly, and the melt-water raised sea level by about 3 meters. cloud A visible mass of condensed water vapor particles or ice suspended above the Earth's surface.

Nieve PenitenteA spike or pillar of compacted snow, firn or glacier ice, caused by differential melting and evaporation.

and on the earth's surface in forms such as hoarfrost, rime, glaze, sea ice, glacier ice, ground ice, frazil, anchor ice, etc.

Katabatic and Anabatic Winds Katabatic winds (taken from the Greek word "katabatikos," meaning "to go down") are sometimes called "gravity winds," "drainage winds," "mountain winds," or "glacier winds.

Erosion: Wearing away of the lands by running water, glaciers, winds, and waves, can be subdivided into three process: Corrasion, Corrosion, and Transportation.

If it falls as snow it can spend some time in a snow or ice-field before moving off as a glacier and perhaps eventually becoming part of an iceberg. Or it might melt and join a river.

Ice ages- Cold time periods in Earth's history, during which glaciers covered large parts of the surface.
Infrared radiation- A form of energy with wave-lengths that are longer than visible light.

Ablation (1) Combined processes (such as sublimation, fusion or melting, evaporation) which remove snow or ice from the surface of a glacier or from a snow-field. Also used to express the quantity lost by these processes.

A chunk of fresh water ice "calved" from a glacier. Icebergs are harder than pack ice.
Intertropical Convergence Zone ...

Little Ice Age The period from about 1550 to 1850 when average global temperatures were lower, and alpine glaciers increased in size and advanced down mountain valleys.
M ...

A local wind which develops due to cool, dense air flowing downhill. The cooler air is generally a result of night time radiational cooling in the lower layers of the atmosphere, but katabatic winds also occur over snow fields and glaciers.

When this air is warm, it may be called a foehn wind, and regionally it may be known as a Chinook or Santa Ana. When this air is cold or cool, it is called a drainage wind, and regionally it may be known as a mountain breeze or glacier wind.
