Any physical process that is caused by the nonlinear terms in the expression of density as a function of S (salinity) and T (temperature) measured at constant pressure. The original meaning of cabbeling is described by considering the mixing of two fluids of similar density but different T and S. The volume of the mixture will generally be slightly smaller than the total volume of the two original fluids (contraction upon mixing). Therefore, the mixture will have a slightly higher density than the average density of the original fluids. This densification upon mixing is thought to cause the mixed fluid to flow downward, away from the zone of mixing, and so will allow new source fluids to come in contact. In situations where vertical mixing is occurring, the effects of nonlinearity are more subtle, leading to differential entrainment and upward migration of the mixing interface.

The value at a particular location in an image; an indication of “brightness” at that location.

Mercury barometer with a fixed cistern. Its scale graduations take account of the changes in the level of the free surface of the mercury in the cistern as a function of atmospheric pressure.
Industry:Weather
The surface drainage, such as the drainage toward the central part of an interior basin, whereby water does not reach the ocean.

Industry:Weather
Hydrograph resulting from storms with a sequence of rainfall events. The resulting hydrograph from one rainfall event continues during the hydrograph for the next rainfall event.

Scattering of x-rays and gamma radiation by matter in which the frequency of the scattered radiation is measurably less than that of the incident radiation (inelastic scattering). So named because Arthur Compton was the first to explain the observed frequency shift by applying the laws of energy and momentum conservation to scattering of a photon by a free electron. Compton's experimental and theoretical investigations established the validity of the quantum theory of radiation, showing that photons possess momentum (and hence can exert radiation pressure) as well as energy.

In fluid mechanics, a dimensionless group that arises in the study of compressible flow. The square of the Mach number, its physical interpretation is the ratio of inertia force (U2) to compressibility force (1/κ), where is density, U is a characteristic speed, and κ is compressibility.

Industry:Weather
The scale of the migratory high and low pressure systems (or cyclone waves) of the troposphere with wave lengths of 1000–4000 km. Terminology in the literature is confusing, chiefly because cyclonic-scale disturbances at low levels are frequently associated with large-scale disturbances in the high troposphere. See barotropic instability, baroclinic instability.
