Structure and evolution of time-dependent intermediate shocks

Abstract
A quantitative description of time-dependent intermediate shocks is formulated using the Cohen-Kulsrud-Burgers equations. In noncoplanar Riemann problems, time-dependent 2→3 intermediate shocks evolve in time as a localized self-similar structure whose strength decreases as 1/ √t , and whose width expands as √t . Time-dependent intermediate shocks offer a way of solving the noncoplanar MHD Riemann problem.
