The liquid content of solid precipitation that has accumulated on the ground (snow depth).
Water equivalent The depth of water that would result from the melting of a snow sample. Typically about 10 inches of snow will melt to 1 inch of water, producing a water equivalent of 10 to 1.
water equivalent—The depth of water that would result from the melting of snow or ice.
waterspout—See tornado.
water vapor—Water in the invisible gaseous form.
Water Equivalent- The liquid content of solid precipitation that has accumulated on the ground (snow depth).
Snow Water Equivalent The water content obtained from melting accumulated snow.
Liquid Water Equivalent - the amount of water estimated from a reflectivity signature on a radar. The liquid water equivalent is computed using an empirical mathematical equation.
Snow water equivalent (SWE)(8)
How much liquid water is contained in a volume of solid snow (in other words, the amount of water measured from melting a known amount of snow).
A snow water equivalent gage based on the absorption of gamma radiation by snow; this gage can measure up to 55 inches water equivalent with a 2 to 5 percent error.
Radiosonde ...
Liquid Water EquivalentSame as Water Equivalent; the liquid content of solid precipitation that has accumulated on the ground (snow depth).
Airborne Snow Water Equivalent Measurement Theory: A theory based on the fact that natural terrestrial gamma radiation is emitted from the potassium, uranium, and thorium radioisotopes in the upper eight inches of the soil.
RadiofaxAbbreviation for radiofacsimile Radioisotope Snow GageA snow water equivalent gage based on the absorption of gamma radiation by snow; this gage can measure up to 55 inches water equivalent with a 2 to 5 percent error.
in shape and about 2 to 5 mm in diameter. Same as graupel or small hail.Snow Pillow1) A window of snow deposited in the immediate lee of a snow fence or ridge.
or
2) In hydrologic terms, an instrument used to measure snow water equivalents.
Snow course An established line or transect of measurements of snow water equivalent across a snow field in representative mountainous terrain, where appreciable snow accumulates, to monitor seasonal snowpack.
It may be observed beneath cumulonimbus or towering cumulus clouds and is the water equivalent of a landspout. WATER VAPOR (H2O) Water in gaseous form. It is one of the most import constituents of the atmosphere.
Airborne Snow Survey ProgramIn hydrologic terms, Center (NOHRSC) program that makes airborne snow water equivalent and soil moisture measurements over large areas of the country that are subject to severe and chronic snowmelt flooding.
The mass balance of a glacier is calculated with the input/output relationships of ice, firn, and snow, usually measured in water equivalent.
While the depth of snow is normally measured in centimetres, the measurement of melted snow (water equivalent) is in millimetres. A estimate of the snow depth can be obtained by multiplying the water equivalent by ten.
Gauges can be adapted to collect snow for the determination of liquid water equivalent of snowfall. Recording rain gauges measure precipitation rates over fixed time intervals to provide an indication of rainfall intensity .
Probability of Precipitation - Probability forecasts are subjective estimates of the chances of encountering measurable precipitation at some time during the forecast period. Measurable means at least 0.2 mm of rain or the water equivalent of ...
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. (2) Reduction of the water equivalent of ...
It is generally weaker than a supercell tornado and is not associated with a wall cloud or mesocyclone. It may be observed beneath cumulonimbus or towering cumulus clouds and is the water equivalent of a landspout.
The more common term rainfall is also used in this total sense to include not only amounts of rain, but also the water equivalents of frozen precipitation. For obvious reasons, precipitation is the preferred general term.
