The nonlinear behavior of whistler waves coupled to either fast magnetosonic waves (FMS) or slow magnetosonic waves (SMS) is investigated in two spatial dimensions. For each branch our investigation is based on a numerical solution of a reduced set of equations consisting of two partial differential
Transverse amplitude modulations of fast magnetosonic waves propagating perpendicular to the background magnetic field are shown to be unstable on a time scale z-~ 211/V, ep, if the wave amplitude ~0 exceeds a critical value, tpc = Cs/V a. The slow modes generated by the modulational instability und
