Ionospheric electric field
WebAn ionospheric model is a mathematical description of the ionosphere as a function of location, altitude, day of year, phase of the sunspot cycle and geomagnetic … Web[8] In this paper, we present the observations of the ionospheric electric and magnetic fields during the passage of interplanetary shocks. The new phenomenon is the occurrence of simultaneous increases in the ionospheric ion velocity and in …

WebThe effect of an ionospheric dynamo electric field on the electron density and total electron content (TEC) perturbations in the F layer (150–600 km altitudes) is investigated at two arbitrarily selected locations (noted as 29° N and 60° N in latitudes) in the presence of seismic tsunami-excited gravity waves propagating in a stratified, nondissipative … Webminutes, of ionospheric electric field to variations in the interplanetary electric field. While the quiet day variations of the equatorial zonal electric field can be described with a climatological model [Scherliess and Fejer, 1999; Alken and Maus, 2010], the prediction of the disturbance electric field is more difficult.

WebAn introduction to the role of ionospheric-layer tilts in long-range HF and VHF radio propagation is given. Tilts in the reflecting layers can have a first-order effect on radio propagation as a consequence of the curvilinear geometry of the earth. Low-angle rays reflected from a properly oriented, sufficiently tilted F layer will propagate beyond the …
