The relation between velocity and pressure gradient in Poiseuille flow.
Industry:Weather
The region of the outer atmosphere in which the dominant gas is hydrogen.
Industry:Weather
The region of the magnetosphere in which the plasma (composed of electrons and positive ions) rotates with the earth. Beyond the plasmapause, magnetospheric convection driven by the interaction of the solar wind with the outer magnetosphere dominates the motion.
Industry:Weather
The reciprocal ''Lg''/''M''<sup>2</sup> of the Froude number, where ''g'' is the acceleration of gravity, ''L'' a characteristic length, and ''M'' a characteristic speed.
Industry:Weather
The region between the subantarctic front and the subtropical front.
Industry:Weather
The region characterized by a convergence of the current in the surface mixed layer (Ekman layer convergence) where water is subducted into the permanent or oceanic thermocline as a result. This region reaches typically from 15°–20° latitude to 45° latitude. Historically, the term subtropical convergence has also been used for the subtropical front.
Industry:Weather
The ratio of the volume of meltwater that can be derived from a sample of snow to the original volume of the sample; strictly speaking, this is the specific gravity of the snow sample. Freshly fallen snow usually has a snow density of 0. 07 to 0. 15; glacial ice formed from compacted snow (or firn) has a maximum density of about 0. 91. Values as low as 0. 004 have been measured. Compare water content, water equivalent.
Industry:Weather
The ratio, expressed as a percentage, of the amount of electromagnetic radiation reflected by the earth's surface to the amount incident upon it. Value varies with wavelength and with the surface composition. For example, snow and ice vary from 80% to 85% and bare ground from 10% to 20%. Compare albedo.
Industry:Weather
The ratio of the volume of water that an initially saturated porous-medium sample retains after being drained by gravity to the volume of the porous medium.
