The small amplitude magnetohydrodynamic Riemann problem is studied using the Cohen–Kulsrud–Burgers equations. Unlike the coplanar Riemann problem, the evolution of noncoplanar Riemann problems is not self-similar and its flow structures could change in time. But its large-time behavior is very simple and a time-dependent 2→3 intermediate shock is always involved for the noncoplanar field rotations. The time-dependent 2→3 intermediate shock has a well-defined structure and exists for any degree of field rotation. [ABSTRACT FROM AUTHOR]
