From page 9...
... The air-earth current varies with magnetic latitude because of the magnetic variations in cosmic-ray fluxes. The current is generally enhanced over orographic features such as mountain ranges because of the decreased columnar resistance (mountains are closer to the ionosphere than the near-sealevel surface)
