The angle between any given ray of scattered radiation and the incident ray. Convention varies as to whether this angle is measured with respect to the direction in which the incident radiation was advancing or with respect to the direction from scatterer to radiation source. See scattering.
Industry:Weather
The smallest root-mean-square sound pressure that can be perceived by an average person without special aids. Usually specified as 0 dB, it corresponds to 2 x 10<sup>−5</sup> N m<sup>−2</sup> or 0. 0002 microbar.
Industry:Weather
The speed of propagation of the wave crest or trough. An alternative definition, useful for linear waves if many wave spectral components are involved, is the frequency multiplied by the wavelength, or the angular frequency divided by the wavenumber.
Industry:Weather
The water content of a soil when an indicator plant (or common agricultural crop) can no longer draw water from the soil, even if atmospheric water demand is zero (near saturated atmosphere and plant and atmosphere at uniform temperature); often estimated as a soil water potential at 15 bars (or atmospheres). For many agricultural soils, this represents a loss of about half the total water-holding capacity of a soil.
Industry:Weather
The upwind direction from a point, for example, westward in the case of a west wind.
Industry:Weather
The time of flow of a parcel or packet of water, contaminant, or tracer from one point to another.
Industry:Weather
The process of measuring a quantity or quantities, transmitting the measured value to a distant station, and there interpreting, indicating, or recording the quantities measured. Typically, spacecraft telemetry includes parameters, such as spacecraft temperature, power supply, and orbital information, that are transmitted to earth to monitor the status of spacecraft.
Industry:Weather
The change in shape of a fluid mass by spatial variations in the velocity field, specifically by stretching or shearing.
A linear analysis of the two-dimensional velocity field can express this field in terms of divergence, vorticity, and deformation (or, more strictly, the rate of deformation)

Industry:Weather
The tendency to build up the mass or density of a given water type (of temperature ''T'' and salinity ''S'' characteristics) due to air–sea fluxes or mixing.
