Abstract

Numerical experiments on two-dimensional compressible convection in the presence of a strong imposed vertical magnetic field reveal several different forms of time-dependent behaviour. As well as the familiar periodic oscillations (standing waves) there are travelling waves, vacillation following secondary instabilities, and streaming instabilities with reversal of the flow. These patterns of behaviour are relevant to sunspot umbrae and to intergranular magnetic fields.
