Abstract
- Abstract: We used Poynting fluxes and densities to investigate the stormtime thermosphere on November 10, 2004. Thermospheric energy, E th which is derived from , consists of two sources, solar ultraviolet radiation (E th UV) and the solar wind (E th SW). Responses of E th SW to interplanetary driving suggest that the thermosphere can be described by the equation dE th SW/dt=αε VS−(E th SW/τ), where ε VS represents the electric field; α and τ are constants. We show that: (1) E th SW is three times the ring-current energy; (2) αε VS is comparable with model predictions; (3) signatures of equatorward propagating disturbances were detected in neutral density profiles.
