The albedo of a surface under conditions of diffuse illumination.
Industry:Weather
That transition zone between earth and atmosphere within which most forms of terrestrial life are commonly found; the outer portion of the geosphere and inner or lower portion of the atmosphere.
Industry:Weather
That part of the stream discharge that is not attributable to direct runoff from precipitation or melting snow; it is usually sustained by groundwater.
Industry:Weather
That static instability in a system in which buoyancy or reduced gravity is the only restoring force on displacements. In general, a fluid is buoyantly unstable when the environmental lapse rate of density is greater than the process lapse rate of density. For an incompressible fluid this requires an increase of density with height; for the atmosphere, when lifting is assumed to be adiabatic, it requires the lapse rate (of temperature) to be greater than the adiabatic lapse rate.
Industry:Weather
Table or graph to facilitate compensation of the instrumental errors of a mercury barometer. The required compensation is generally very small and is normally included in the barometric reduction table. See compensation of instruments.
Industry:Weather
Table for the reduction of station mercury barometer readings in conditions of standard temperature and gravity and, if required, to a standard level (normally mean sea level). Compare station pressure.
Industry:Weather
Stratus clouds with tops that are warmer than the surrounding cloud-free ground. The name is derived from satellite imagery that is often displayed as black and white imagery with warmer temperatures portrayed in darker shades of gray. In this case, stratus can stand out as dark (warm) objects above a lighter (cooler) background.
Industry:Weather
Southward flowing current on the eastern side of Baffin Bay with speeds of 0. 2– 0. 4 m s−1. It is fed by low-salinity water from the Arctic Ocean, thus contributing to the freshwater budget between the Pacific and Atlantic, and by the West Greenland Current. It feeds the Labrador Current.
