Abstract
The upper atmosphere is strongly influenced by the convergence of energy, mass, and momentum flux from coupled but distant regions. In the polar regions, these sources include not only wave fluxes from the lower atmosphere and vacuum ultraviolet fluxes from the sun, but also fluxes of electromagnetic and kinetic energy of magnetospheric origin. Magnetospheric fluxes can constitute the dominant energy fluxes received by the polar atmosphere above 80 km . The way that the upper atmosphere responds to these sources depends on the upper atmospheric state, the type of energy source impacting the upper atmosphere, and the source's spatial and temporal scale. Furthermore, the upper atmosphere and ionosphere are electrodynamically and intertially coupled to the magnetospheric energy sources, such that the source type, its magnitude, and its structure can be altered by the condition and response of the polar upper atmosphere. It is the intention of this paper to elaborate on this complex interplay between the magnetosphere and the polar regions, with an emphasis on the polar aeronomic behavior and its influence on the magnetospheric sources.
