A descent profile determined for vertical guidance during a final approach or landing of an aircraft. See instrument landing system.
Industry:Weather
A cloud species in which the cloud elements are irregular but generally small in size, and that presents a ragged, shredded appearance, as if torn. All of these characteristics change ceaselessly and often rapidly. Stratus fractus is distinguishable from cumulus fractus by its smaller vertical extent, darker color, and by the greater dispersion of its particles. Cumulus fractus actually looks like a ragged cumulus cloud. The species fractus occurs only in the genera mentioned above. See cloud classification, scud.
Industry:Weather
A collection of waves, the amplitudes of which have a Gaussian dependence on wavenumber about some central wavenumber.
Industry:Weather
A condensation cloud, typically funnel-shaped and extending outward from a cumuliform cloud, associated with a rotating column of air (a vortex) that may or may not be in contact with the ground. If the rotation is violent and in contact with the ground, the vortex is a tornado. Funnel clouds can occur through a variety of processes in association with convection. For example, small funnel clouds are infrequently seen extending from small, dissipating cumulus clouds in environments with significant vertical wind shear in the cloud-bearing layer.
Industry:Weather
A contraction of the words fume and cumulus, indicating water-droplet clouds that form within the top of rising plumes from smokestacks, cooling towers, or open fires.
Industry:Weather
A coordinate system with its origin at the earth's center, as distinct from one with an origin on the earth's surface.
Industry:Weather
A coordinate used in geomagnetism bearing the same relation to the geomagnetic dipole equator as geographic latitude does to the geographic equator. When meridional variations in phenomena closely related to the earth's magnetic field are plotted according to geomagnetic rather than geographic latitude, more clear-cut relations are usually depicted. Cosmic ray intensities and auroral frequencies are examples of quantities best studied as functions of this type of latitude.
