The departure of an element from its long-term average for the location concerned.
Climatic elements include precipitation, temperature, humidity, sunshine and wind velocity and phenomena such as fog, frost, and hail storms.
Sometimes it is confused with altocumulus, however, it has smaller individual masses and does not cast a shadow on other elements.
StratocumulusLow-level clouds, existing in a relatively flat layer but having individual elements. Elements often are arranged in rows, bands, or waves.
ParameterA subset of the group of evaluations that constitute each element of an observation.
A part of the National Weather Service which provides nationwide computerized and manual guidance to Warning and Forecast Offices concerning the forecast of basic weather elements.
capping inversionAn elevated inversion layer that caps a convective boundary layer, keeping the convective elements from rising higher into the atmosphere.
carbon pool The reservoir containing carbon as a principal element in the geochemical cycle. carbon sink A pool (reservoir) that absorbs or takes up released carbon from another part of the carbon cycle.
cumulus - (Abbreviated Cu.) A principal cloud type (cloud genus) in the form of individual, detached elements that are generally dense and posses sharp nonfibrous outlines.

Cirrocumulus(Cc) They are thin clouds, the individual elements which appear as small white flakes or patches of cotton, usually sowing brilliant and glittering quality suggestive of ice crystals.
CELL - A precipitation element, usually associated with convective precipitation such as thunderstorms. The term is also applied to an individual storm or weather system component as a low-pressure (or high-pressure) cell.
Photons: Particles of light, the elementary quantity of radiant energy.
Potential energy: The energy an object has by virtue of its position.
Power: The rate of change of energy over time, often expressed in watts.
