From: 3-D global hybrid simulations of magnetospheric response to foreshock processes
Case I: power spectra of the compressional and toroidal components from the foreshock into the magnetosphere as a function of X along the Sun–Earth line. Note that the spectrum of the self-consistently generated foreshock waves covers a wide frequency range including \(\sim ~\Omega _{{i0}} /2\). The average bow shock and magnetopause positions are marked by the vertical dashed lines
