• Nonlinear magnetosonic waves in a turbulent plasma, characterized by an effective electrical conductivity σ_eff due to micro-instabilities, are governed by the Burgers type equation, which has a shock-like stationary solution. It is shown that initial magnetic pulses of gaussian and solitary wave forms first decay due to dissipation, and subsequently form a shock front whose steepness is determined by the opposing effects of nonlinearity and dissipation. This process is thought to be important in connection with shock formation in space plasmas.
