The chemical turbulence of the Belousov-Zhabotinsky reaction theoretically expected by Kuramoto and Yamada was experimentally studied. The turbulence is caused by the coupling between diffusion and nonlinear reaction, i.e., a diffusion induced chaos. Qualitative features of the turbulence are as follows: (1) the turbulence is characterized by frequent growth and decay of plural modes, (2) the alternation of modes corresponds to the irregular variation of the amplitude, (3) the extent of disorder varies gradually with controllable parameters and there seems to be no discontinuity between turbulent and ordered phases.
