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 meteorology, the point of intersection of a trough and a ridge in the pressure pattern of a weather map. It is the point of relatively lowest pressure between two highs and the point of relatively highest pressure between two lows.

A wave for which the primary restoring force is surface tension; generally taken to be one of less than 1. 7-cm wavelength, this being the wavelength for which the theoretical phase speed is a minimum, and marking the transition from gravity to surface tension as the dominant restoring force at the sea surface. Compare gravity wave.

Any scheme for the unique identification of each point of a given continuum. These may be points in space (Eulerian coordinates) or parcels of a moving fluid (Lagrangian coordinates). Newton's laws of motion do take different forms in different systems (see inertial coordinate system, relative coordinate system). The geometry of the system is a matter of convenience determined by the boundaries of the continuum or by other considerations (see Cartesian coordinates, curvilinear coordinates).

In popular terminology, any sudden and heavy fall of rain, almost always of the shower type. An unofficial criterion sometimes used specifies a rate of fall equal to or greater than 100 mm (3. 94 inches) per hour. See excessive precipitation.
