Evolution of the potential map over the north polar cap, showing the pattern of convection cells. The maps are based on six years of Cluster EDI data and show the variation of the potential in the ionosphere at 400 km altitude as a function of the orientation of the interplanetary magnetic field (IMF). The potential strength is colour coded and the maximum and minimum values, as well as the total potential difference, are stated at the top. The orientation of the IMF is indicated at top right with the yellow cone (45° wide).
