Fluid motion having a velocity field characterized by the presence of velocity shear.
Industry:Weather
Flow with a celerity greater than that of a gravity wave. Equivalently, flow for which the Froude number is greater than 1.
Industry:Weather
Flood used to design a dam spillway; also, maximum flow that could pass through a spillway without causing serious structural damage.
Industry:Weather
Fine particulate mass, mostly carbon, that is emitted as a result of incomplete fuel combustion.
Industry:Weather
Extremely unreactive gas, formula SF<sub>6</sub>, which is of entirely anthropogenic origin. It is used as a dielectric insulator or to provide a chemically inert atmosphere. Due to its inertness, SF<sub>6</sub> has a very long atmospheric lifetime (>1000 years) and has been used to estimate the age of stratospheric air. It is also used as a chemical tracer in tropospheric field experiments.
Industry:Weather
Extensive region of the earth's surface characterized by essentially uniform surface conditions, and so located with respect to the general atmospheric circulation pattern that a volume of air remains in contact with the surface long enough to acquire properties that distinguish it as an air mass (e.g., central Canada for continental polar air). See airmass source region.
Industry:Weather
Energy emitted by the sun at wavelengths detected by radio receivers; in particular, radio noise produced by solar disturbances, especially solar flares.
Industry:Weather
Emission of subatomic particles (and/or photons) stimulated by primary radiation, for example, cosmic rays impinging on other particles and causing them, by disruption of their electron configurations or even of their nuclei, to emit particles and/or photons in turn.
