Winterhalter, D. and Kivelson, M.G. (1988). Observations of the earth’s bow shock under high mach number/high plasma beta solar wind conditions. Geophysical Research Letters 15: doi: 10.1029/88GL03373. issn: 0094-8276.

Using 221 observations of the earth's bow shock by ISEE-1 we investigate the magnetic field characteristics of the shock as a function of Mach number and plasma beta. We find that immediately behind the overshoot of the shock large amplitude waves develop preferentially with increasing Alfv¿n Mach number and/or plasma beta. Their probability of occurrence is very high in the parallel regime (&thgr;BN≤10¿), and declines to near zero probability when &thgr;BN reaches 75¿. It is estimated that approximately 10% of the total solar wind energy density is dissipated by these waves. ¿ American Geophysical Union 1988
