| Abstract: | It is shown that the pattern of convection at high latitudes when the IMF is northward is the sum of two types of convection: (a) four-vortex convection completely closed in high latitudes and (b) homogeneous sunward convection across all high-latitude regions including the auroral zone. The decay of the three-dimensional current system which existed before the turning of IMF northwards may maintain the homogeneous sunward convection. |
