Fig. 7From: Simulation of horizontal sporadic E layer movement driven by atmospheric tidesHorizontal distributions of a Mg\(^+\) density, b zonal winds (eastward positive), and c meridional winds (southward positive) at low-latitudes around Arecibo at 103 km and 6 LT. The Es structures correspond to the lower Es layer in Fig. 1d. The contours in Fig. 7a represent the geomagnetic zonal wind velocityBack to article page
