Defined traditionally as the mean height of the highest third of the waves, but now usually defined as four times the root-mean-square of the surface elevation (or equivalently as four times the square root of the first moment of the wave spectrum).
Industry:Weather
Day length or duration of daily exposure to light and dark periods, either natural or artificially manipulated.
Industry:Weather
Data or observations for which the reporting or recording of events is nearly simultaneous with their occurrence. It is distinguished from archival retrieval of the data.
Industry:Weather
Current of air in which the ground-relative motion does not have any significant curvature. Used in the context of surface winds that inflict damage; to be distinguished from winds in tornadoes, which have significant curvature.
Industry:Weather
Cross-valley winds that are driven up or down sloping terrain by buoyant forces. Examples are anabatic (upslope) winds caused by rising warm air during daytime and katabatic (downslope) winds caused by descending cold air at night. Compare slope flows.
Industry:Weather
Critical liquid water content for growth by accretion of a hailstone or other object in a supercooled cloud such that for a given temperature and air speed all the accreted water is frozen and the surface temperature is above 0°C. Above this limit more water is accreted than can be frozen and either is shed as liquid or is retained as spongy ice.
Industry:Weather
Conventional pattern for the plotting of symbols around a station location on a synoptic chart.
Industry:Weather
Conventional ideograms on a meteorological chart or in a message that represent various meteorological observations.
Industry:Weather
Conjectural; in statistical analysis, a synonym for random.
Industry:Weather
Concentration of dissolved salts in a body of water.
