The parametric decay of a monochromatic Alfvén wave in a low beta plasma is found to decay into a forward propagating density mode and a backward propagating daughter Alfvén wave mode. In this paper, by performing one-dimensional (1-D) hybrid simulations, we detailedly analyze the parametric instabilities of the Alfvén waves with a spectrum in a low beta plasma. The results show that the parametric instabilities have two stages. In the first stage, the density wave modes are excited due to the modulation of the pump Alfvén waves, and then magnetic fluctuations appear after these density modes interact with the pump Alfvén waves. In the second stage, each pump Alfvén wave will decay into a density mode and a daughter Alfvén wave mode, as in the parametric decay of a monochromatic Alfvén wave.

Keywords:space physics; Alfvén wave; Parametric instability; spectrum; hybrid simulation
