Abstract The rate of amplification of a discontinuity in the slope of the field variables (velocity, pressure, etc.) at the head of a disturbance is evaluated for propagation through a homogeneous exploding atmosphere. The calculation is first performed using a linear theory, with rather general chemistry. The effects of non-linearity are then identified and calculated, and this leads to some general results for planar, cylindrical and spherical wave fronts. By adopting a simple model for the chemical reaction the problem of calculating the details of planar wave-head behaviour is overcome and it becomes possible to see how an exothermic explosive event expedites the formation of shock waves at a wave head.
