Fig. 8From: Transmission of the electric fields to the low latitude ionosphere in the magnetosphere-ionosphere current circuitGeomagnetic storm recorded at low latitude, Okinawa (OKI) and equator, Guam (GAM) and Yap, Micronesia (YAP) in the western Pacific region. The storm is enhanced at YAP with an enhancement ratio of 2.7, caused by combined effects of the main phase EEJ and recovery phase CEJ. (from Fig. 6 of Kikuchi et al. 2008)Back to article page
