EM and T_EM evolution for two positions on the linear cut-a (cf. Fig. 5). The red curve is data from a position passed by the SAD, while the black curve corresponds to a position outside of the SAD. Additional lines are used to highlight features in the red curves. Two vertical lines indicate the selected time interval (II), in which the temporary EM decrease occurs. Horizontal lines highlight the corresponding initial EM value (EM₁), minimum EM value (EM₂), initial temperature (T₁), average maximum temperature (T₂) during passage of the SAD, and the temperature (T₃) afterwards.
