From the Greek “nephele,” cloud, usually applied to measurement of the angular dependence of scattering of electromagnetic radiation by a suspension of particles.
Industry:Weather
In nephanalysis, a line bounding a significant portion of a cloud system that permits the analyst to extract information. Examples are clear-sky lines, precipitation lines, cloud-type lines, ceiling-height lines. Compare isoneph.
Industry:Weather
The analysis of a synoptic chart focusing on the types and amount of clouds and precipitation. Cloud systems (or nephsystems) are identified both as entities and in relation to analysis features determined from other information. A chart of this type is sometimes termed a neph chart. See isoneph, nephcurve.
Industry:Weather
A sequence of interactions that damps or reduces the response to an initial perturbation. For example, consider a surface that is subjected to an increase in incoming radiation. This change in the energy balance produces an increase in temperature which, by virtue of the Stefan– Boltzmann law, results in an increase in the radiation emitted by the surface. Thus, the interaction by temperature and radiation acts to partially counteract the original perturbation. Compare positive feedback.
Industry:Weather
The advection of negative vorticity along an isothermal surface.
Industry:Weather
(Symbol Ne. ) An inert gas that is the second member of the noble gas family, atomic number 10, atomic weight 20. 183. It is a colorless, odorless, monatomic element found in the atmosphere to the extent of about 0. 0018% by volume of dry air.
Industry:Weather
A characteristic of a system in which momentum is transferred from a region of lower velocity toward a flow of higher velocity, increasing the mean wind shear. Compare viscosity.
