Web(EEJ) currents. At the lower portion of the ionosphere, known as the E-region (90-120 km altitude), near the equator these currents can be enhanced even further by the horizontal geometry of the geomagnetic main field in addition to the zonal electric field component. The zonal electric field near the equator drives verti- Webcurrents flowing to the ionosphere. Electric fields are also induced in the ionosphere by the winds blowing there, and polarization fields are pro- duced when electric currents in the ionosphere flow through regions of varying conductivity a In the theories by COLE ( 1960) and SWIFT ( 1963) the ionospheric winds have been how much outstanding student loan debt
