Modeling seasonal variations of auroral particle precipitation in a global-scale magnetosphere-ionosphere simulation
[1] A variety of observations have shown strong seasonal variations in a vast array of magnetosphere-ionosphere parameters, including field-aligned currents, cross polar cap potential, and precipitating electron energy flux. In this paper we examine how these variations are modeled in the Lyon-Fedder-Mobarry (LFM) global-scale magnetohydrodynamic simulation of the coupled solar wind-magnetosphe...
متن کاملThe Chemical Effects of Auroral Oxygen Precipitation
Energetic oxygen precipitation is one possible explanation for the auroral molecular hydrogen emissions observed by the Voyager ultraviolet spectrometer. These ions deposit their energy in the Jovian thermosphere by means of ionization, dissociation, excitation, and heating processes. The photochemistry of both the neutral gas and the ionosphere is altered by the influx of atomic oxygen. The au...
متن کاملStudy of auroral forms and electron precipitation with the IRIS, DASI and EISCAT systems
Simultaneous observations with the IRIS, DASI and EISCAT systems are employed in the study of the spatial distribution and temporal evolution of auroral forms and precipitation regions during substorm activity. The evolution of the spectrum of precipitating electrons above Tromsø during the various phases of substorms is discussed. The flux-energy spectrum in the 1–320 keV range is derived from...
متن کاملEvaluation of seasonal variation in acne vulgaris
Background and Aim: Acne vulgaris is one of the most common skin diseases in adolescents and young adults. Although acne do not physically disable the patient, it can cause significant psychological morbidities. The disease etiology is not fully understood; however, there are several factors involved in the pathogenesis. The aim of this study is to investigate the seasonal variation of acne vul...
متن کاملResonant scattering of plasma sheet electrons leading to diffuse auroral precipitation: 1. Evaluation for electrostatic electron cyclotron harmonic waves
[1] Using statistical wave power spectral profiles obtained from CRRES and the latitudinal distributions of wave propagation modeled by the HOTRAY code, a quantitative analysis has been performed on the scattering of plasma sheet electrons into the diffuse auroral zone by multiband electrostatic electron cyclotron harmonic (ECH) emissions near L = 6 within the 0000–0600 MLT sector. The results ...
