The chaos can appear in internalowave dynamics (i. e. the deterministic aperiodic flow). The chaos are the results of the forcing factor and dissipative factor. The chaos do not appear because of the too weak dissipative factor when Prandtl number σ=1 in the Lorenz equation. The concept of chaos may explain the onset of turbulence.We argue that the chaotic motion can appear when the velocity shear damper is added to Lorenz equation for the Plandtl number σ=0.7. The atmosphere is stable at night. But we add a forcing heating source to the thermodynamic equation, and the chaos can appear similarly.
