    In the present study, the dissipation processes of circularly polarized Alfvén waves in solar wind plasmas including beam components are numerically discussed by using a 2-D hybrid simulation code. Numerical results suggest that the parent Alfvén waves are rapidly dissipated due to the presence of the beam-induced obliquely propagating waves, such as kinetic Alfvén waves. The nonlinear wave-wave coupling is directly evaluated by using the induction equation for the parent wave. It is also observed both in the 1-D and 2-D simulations that the presence of large amplitude Alfvén waves strongly suppresses the beam instabilities.
