Magnetic-field-aligned mapping from the ionosphere to the current sheet using the Tsyganenko 1989 field model is employed to investigate the relationship between the auroral and tail processes during the substorm growth phase. The dynamical changes in the field and current distributions are modeled by stepwise modification of the field model to include the current sheet thinning and enhancement of the tail current. The field signatures of a current meander suggested to form in the tail are demonstrated. These signatures are compared with a model where line currents are added to represent the effects of the current wedge forming at substorm onset. If the observed motion of the arc is interpreted to be entirely due to the stretching of the tail field during the growth phase, the enhancement of the cross-tail current and the changes in the field configuration can be estimated.
