Structural analysis of various types of magnetohydrodynamic shocks demonstrates that current instability can develop at the shock front. As the energy of the plasma waves excited by the instability is absorbed, streams of high-energy electrons are produced ahead of and behind the front. The Langmuir waves generated by these streams will be transformed into type II solar radio emission at irregularities in the shock front. The splitting observed in type II bursts in attributed to the MHD effect of shock splitting.
