The equatorial horizontal component actually reversed in sign from the normal westward value and, simultaneously, the electro­jet then flowing over the dayside hemisphere (at Trivandrum, India, fer example) was greatly depressed. These results show that intense auroral current systems can grossly affect both the normal dynamo current patterns at low latitudes en the dayside and the polarization fields responsible fer the worldwide low latitude zonal electric field component.application/pdfenginfo:eu-repo/semantics/openAccessAuroral areasMeasurementsElectric fieldsinfo:eu-repo/semantics/conferenceObjecthttp://purl.org/pe-repo/ocde/ford#1.05.01
