Fig. 2From: Simulation of horizontal sporadic E layer movement driven by atmospheric tidesHorizontal distributions at 112.5 km and 7 LT for a Mg\(^+\) density, b zonal winds (eastward positive), and c meridional winds (southward positive) at mid-latitudes around Japan. The contours in Fig. 2a represent the geomagnetic zonal wind velocityBack to article page
