Abstract [en]

This review summarizes the current understanding of transpolar arcs. The following topics are covered: (1) transpolar arc (TPA) types, (2) influence of interplanetary magnetic field (IMF) B-y and B-z on shape and motion of TPAs, (3) temporal intensifications of TPAs, (4) substorms and TPAs, (5) solar wind energy coupling, (6) ionospheric convection and source regions of TPAs, (7) interhemispheric differences caused by IMF B-x, (8) interhemispheric differences caused by the Earth dipole tilt, and (9) magnetotail topology during TPAs.
