AB: We use global hybrid simulations to study the formation and evolution of density cavities and ultra low frequency (ULF) waves in the foreshock. We also study the effects that these structures can have on processing the solar wind in the foreshock, on bow shock structure and ultimately on solar wind coupling with the magnetosphere. Global hybrid simulations give a collective picture of processes taking place in the foreshock, bow shock and magnetosheath. Because ions are treated as particles, these codes also give information on ion-scale microphysics allowing us to understand how kinetic phenomena modulate global characteristics. Simulation results are compared with observations.
