Fig. 6: Schematic of the interaction of foreshock waves with the shock.

Summary of our findings and the scenario we propose for the interaction of foreshock waves with the shock and the resulting waves and structures in the magnetosheath. The wave propagation is shown from left to right, from the foreshock away from the shock (light purple) to the magnetosheath (green). The relevant properties of the 30 s waves are indicated in the foreshock (left) and just upstream of the shock (second from the left). The processes occurring upon their interaction with the shock are marked in the third box (dark purple). The resulting waves and structures in the magnetosheath are listed in the rightmost box (green).
