Radiation that has undergone one or more scattering processes. See'' also'' diffuse radiation, single-scattering, multiple-scattering.
Industry:Weather
Products of the degradation of atmospheric emissions resulting from photooxidation processes. Products include ozone, nitrogen dioxide, and peroxyacetyl nitrate, all of which contribute to the total oxidant concentration.
Industry:Weather
Prognostic chart for a given time, that is, 24 hours ahead of the surface synoptic situation.
Industry:Weather
Propagation of a shock front, a narrow region in a fluid over which its thermodynamic state changes markedly. The thickness of the front is of order a few mean free paths in the medium ahead of the wave.
Industry:Weather
Propagation of electromagnetic waves by irregularities in the refractive index of the propagation medium. See tropospheric scatter.
Industry:Weather
Property of an air mass that is typical of the air mass as a whole and thus may be used in airmass analysis.
Industry:Weather
Proportionate frequency per observation. If an event occurs ''N''′ times in ''N'' trials, its relative frequency is ''N''′/''N''. Relative frequency is the empirical counterpart of probability.
Industry:Weather
Pressure in head units, for example, meters of fluid, equal to the force per unit area divided by the product of the density of the fluid and the acceleration due to gravity. It is the depth of fluid that would exert an equivalent pressure.
Industry:Weather
Process by which cells containing chlorophyll in green plants convert incident light to chemical energy and synthesize organic compounds from inorganic compounds, especially carbohydrates from carbon dioxide and water, accompanied by the simultaneous release of oxygen.
