Distributions of the model \(\Delta B_{x}=0.5\left (B_{x}^{(N)}-B_{x}^{(S)}\right)\) (proportional to the current per tail unit length) along the x-axis for four combinations of the interplanetary driving parameters. Black and green solid lines correspond to the tilted (Ψ=30°) and perpendicular (Ψ=0) orientation of the geodipole, respectively. Red and blue dashed lines show the southern and northern lobe field variation, respectively
