MAGNETOSPHERE. “The solar wind motional electric field in the Earth’s frame of reference imposes a large-scale convection pattern within the magnetosphere and ionosphere. Dayside reconnection allows solar wind plasma and field entry to the dayside magnetosphere, from where the plasma convects across the polar cap and tail lobes to another reconnection location in the distant tail.”
