Fig. 207. Schematic representation of the oceanic structure in a cross-section normal to the 

 Agulhas Current and the West Wind Drift south of Africa. Shaded, heavier water masses; 

 non-shaded, lighter water masses; dashed lines, isobaric surfaces of this system; thin full 

 arrows in A and A', corresponding currents, in A from west towards east, in A' from east 

 towards west. Superimposed the pressure field of a water-"stau" in the central region; thin 

 full lines in the cross-section: isobaric surfaces, dashed in A, B and A', B': corresponding 

 currents, in A and B from east towards west, in A' and B' from west towards east. Thick full 

 lines in the section: resulting pressure field of the final current system. Thick full arrows 

 underneath: direction and speed of the resulting currents; in A and B from east towards 

 west, in A' and B' from west towards east.
